Policy Adopted by NFPA Board of Directors on December 3, 1982 The Board of Directors reaffirms that the National Fire Protection Association recognizes that the toxicity of the products of combustion is an important factor in the loss of life from fire. NFPA has dealt with that subject in its technical committee documen'ts for many years. •There is a concern that the growing use of synthetic materials may produce more or additional toxic products of combustion in a fire environment. The Board has, therefore, asked all NFPA technical committees to review the documents for which they are responsible to be sure that the documents respond to this current concern. To assist the committees in meeting this request, the Board has appointed an advisory committee to provide specific guidance to the technical committees on questions relating to assessing the hazards of the products of combustion.

NFPA 72E Standard on

A u t o m a t i c Fire D e t e c t o r s 1990 Edition

This edition of NFPA 72E, Standard on Automatic Fire Detectors, was prepared by the Technical Committee on Detection Devices, released by the Correlating Committee on Signaling Systems, and acted on by the National Fire Protection Association, Inc. at its Annual Meeting held May 21-24, 1990 in San Antonio, TX. It was issued by the Standards Council on July 20, 1990, with an effective date of August 17, 1990, and supersedes all previous editions. T h e 1990 edition of'this document has been approved by the American National Standards Institute. Changes other than editorial are indicated by a vertical rule in the margin of the pages on which they appear. These lines are included as an aid to the user in identifying changes from the previous edition.

Origin and Development of NFPA 72E This standard was written to assist in the proper use of automatic fire detectors. Technology has produced a large n u m b e r of devices that respond to some p h e n o m e n o n of fire. To operate effectively, these devices must be located properly within the protected space. There are various types of fires - - fast or slow, flaming or smoldering -- but each is a specific product of the type and form of fuel on which it feeds and the physical size and shape of the space in which it starts. An automatic fire detector should be selected after identification of both the type and size of fire to be detected and the response required. These detectors should be located in that space so that they are properly responsive to these fires. The Committee recognizes the need for additional fire research. The Fire Detection Institute (FD1) is expected to perform these needed tasks. The current edition of this standard is based on the best information known to date. The standard will be refined as results and additional information are received and studied. The first edition of this standard was submitted and adopted as a tentative standard in May 1972. The standard was adopted as an official standard in 1974. The 1978 edition contained a complete revision of Chapter 4, "Smoke Sensing Fire Detectors," a new Chapter 6, "Gas Sensing Fire Detectors," and other revisions. In 1982, a new table, "Fable 3-5.1.2, addressing spacing of heat detectors on. high ceilings, was added. In the 1984 edition, Chapter 9 was completely revised to cover the use of detectors in air duct systems and to provide guidance in correlation with NFPA 90A, Standard for the hlstallation of Air Conditioning and Ventilating Systems, on the use of detectors for control of smoke spread. Also, NFPA 72E-M was incorporated into NFPA 72E as new AppendiX C.

The new material is the result of data developed by the Fire Detection Institute as a guide to spacing of heat detectors on other than 15-ft ceilings. The 1987 edition was a complete rewrite of the standard. Many of the changes were for clarification. Appendix C was expanded to include tables used to analyze an existing heat detection system. The 1990 edition of NFPA 72E is a partial revision of this standard. The major change was a total revision and expansion of Chapter 5, "Flame Sensing Fire Detectors."

Chapter 1

Introduction

1-1 Purpose. 1-1.1 T h e purpose of this standard is to provide basic m i n i m u m requirements for the performance of automatic fire detectors to ensure timely warning for the purposes of life safety and property protection. 1-1.2 This standard is intended for use by persons knowledgeable in the application of fire detection as part of fire protection systems.

1-2 Scope. 1-2.1 This standard covers m i n i m u m performance, location, mounting, testing, and maintenance requirements of automatic fire detectors for protection of the occupant, building, space, structure, area, or object to be protected in accordance with the stated purpose. 1-2.2 This standard is intended to be used with other NFPA standards that deal specifically with fire alarm, extinguishment, or control. Automatic fire detectors add to fire protection by initiating emergency action, but only where used in conjunction with other equipment. 1-2.3 The interconnection of detectors, the control conf i g u r a t i o n s , the power supply, or the o u t p u t systems r e s p o n d i n g to a u t o m a t i c fire d e t e c t o r a c t u a t i o n are J detailed in NFPA 71, Standard for the Installation, Mainte-

Common Requirements

2-1 General. Fire is a p h e n o m e n o n that occurs when a substance reaches a critical temperature and reacts chemically with oxygen (for example) to produce heat, flame, light, smoke, water vapor, carbon monoxide, carbon dioxide, or other products and effects. An automatic fire detector is a device designed to detect the presence of fire and initiate action. 2-1.1 Definitions.

Approved. Acceptable to the "authority having jurisdiction." NOTE: The National Fire Protection Association does not approve, inspect or certify any installations, procedures, equipment, or materials nor does it approve or evaluate testing laboratories. In determining the acceptability of installations or procedures, equipment or materials, the authority having jurisdiction may base acceptance on compliance with NFPA or other appropriate standards. In the absence of such standards, said authority may require evidence of proper installation, procedure or use. The authority having jurisdiction may also refer to the listings or labeling practices of an organization concerned with product evaluations which is in a position to determine compliance with appropriate standards for the current production of listed items.

Authority Having Jurisdiction. The "authority having j u r i s d i c t i o n " is the o r g a n i z a t i o n , office or i n d i v i d u a l responsible for "approving" equipment, an installation or a procedure. NOTE: The phrase "authority having jurisdiction" is used in NFPA documents in a broad manner since jurisdictions and "approval" agencies vary as do their responsibilities. Where public safety is primary, the "authority having jurisdiction" may be a federal, state, local or other regional department or individual such as a fire chief, fire marshal, chief of a fire prevention bureau, labor department, health department, building official, electrical inspector, or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company representative may be the "authority having jurisdiction." In many circumstarices the property owner or his designated agent assumes the role of the "authority having jurisdiction"; at government installations, the commanding officer or departmental official may be the "authority having jurisdiction." Ceiling. The upper surface of a space, regardless of height. Areas with a suspended ceiling would have two ceilings, one visible from the floor and one above the sus= pended ceiling.

nance, and Use of Signaling Systemsfor Central Station Service, NFPA 72, Standard for the Installation, Maintenance and Use of Protective Signaling Systems, NFPA 74, Standard for the Installation, Maintenance, and Use of Household Fire Warning Equipment, and others.

Ceiling Height. The height from the continuous floor of the room to the continuous ceiling of a room or space.

1-2.4 Nothing in this standard is intended to prevent the use of new methods or devices provided sufficient technical data are submitted to the authority having jurisdiction to demonstrate that the new method or device is equivalent in quality, effectiveness, durability, and safety to that prescribed by this standard.

Combination Detector. A device that either responds to more than one of the fire p h e n o m e n a classified i n 2-2.1.1 through 2-2.1.5, or employs more than one operating principle to sense one of these p h e n o m e n a . Typical examples are a combination of heat detector with smoke detector or a combination rate-of-rise and fixed temperature heat detector.

AUTOMATIC FIRE DETECTORS

Labeled. Equipment or materials to which has been attached a label, symbol or other identifying mark of an organization acceptable to the "authority having jurisdiction" and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials and by whose labeling the manufacturer indicates compliance with a p p r o p r i a t e standards or performance in a specified manner. Listed. Equipment or materials included in a list published by an organization acceptable to the "authority having jurisdiction" and concerned with p r o d u c t evaluation, that maintains periodic inspection of production of listed equipment or materials and whose listing states either that the equipment or material meets a p p r o p r i a t e standards or has been tested and found suitable for use in a specified manner. NOTE: The means for identifying listed equipment may vary for each organization concerned with product evaluation, some of which do not recognize equipment as listed unless it is also labeled. The "authority having jurisdiction" should utilize the system employed by the listing organization to identify a listed product. Shall.

2-2.2.2 Spot-type Detector. A device whose detecting elem e n t is c o n c e n t r a t e d at a p a r t i c u l a r location. Typical examples are bimetallic detectors, fusible alloy detectors, certain p n e u m a t i c rate-of-rise detectors, certain smoke detectors, and thermoelectric detectors. 2-2.2.3 Air Sampling-type Detector. A s a m p l i n g - t y p e detector consists of piping or tubing distribution from the detector unit to the area(s) to be protected. An air p u m p draws air from the protected area back to the detector through the air sampling ports and piping or tubing. At the detector, the air is analyzed for fire products.

2-2.3 Operating Modes. 2-2.3.1 Nonrestorable Detector. A device whose sensing e l e m e n t is designed to be d e s t r o y e d by the process of detecting a fire. 2-2.3.2 Restorable Detector. A device whose sensing element is not ordinarily destroyed by the process of detecting a fire. Restoration may be manual or automatic.

AUTOMATIC FI RE DETECTORS

Heat Sensing Fire Detectors

3-1 Heat is a d d e d energy that causes substances to rise in t e m p e r a t u r e as well as the energy p r o d u c e d by a b u r n i n g substance.

3-1.1 General. 3.1.1.1 T h e p u r p o s e and scope of this chapter are to provide standards for location and spacing of fire detectors that sense heat p r o d u c e d by b u r n i n g substances. T h e detectors are usually refei'red to as heat detectors. 3-1.1.2 Heat detectors, shall be installed in all areas where required either by the a p p r o p r i a t e NFPA standard or the authority having jurisdiction.

3-2 Operating Principles.

3-2.2 Rate Compensation Detector. 3-2.2.1 A rate compensation detector is a device that will respond when the t e m p e r a t u r e of the air s u r r o u n d i n g the device reaches a p r e d e t e r m i n e d level, regardless of the rate of t e m p e r a t u r e rise. 3-2.2.2 A typical example is a spot-type detector with a tubular casing of a metal that tends to e x p a n d lengthwise as it is heated and an associated contact mechanism that will close at a certain point in the elongation. A second metallic element inside the tube exerts an opposing force on the contacts, tending to hold them open. T h e forces are balanced in such a way that, on a slow rate of t e m p e r a t u r e rise, there is more time for heat to penetrate to the inner element, which inhibits contact closure until the total device has been heated to its rated t e m p e r a t u r e level. However, on a fast rate of t e m p e r a t u r e rise, there is not as much time for heat to penetrate to the inner element, which exerts less of an inhibiting effect so that contact closure is obtained when the total device has been heated to a lower level. This, in effect, compensates for thermal lag.

3-2.1 Fixed Temperature Detector. 3-2.3 Rate.of-Rise Detector. 3-2.1.1 A fixed t e m p e r a t u r e detector is a device that will respond when its operating element becomes heated to a p r e d e t e r m i n e d level. 3-2.1.2 T h e r m a l Lag. When a fixed t e m p e r a t u r e device operates, the t e m p e r a t u r e of the s u r r o u n d i n g air will always be higher than the operating t e m p e r a t u r e of the device itself. This difference between the o p e r a t i n g temperature of the device and the actual air t e m p e r a t u r e is commonly spoken of as thermal lag, and is proportional to the rate at which the t e m p e r a t u r e is rising. 3-2.1.3 Typical examples of fixed t e m p e r a t u r e sensing elements are: (a) Bimetallic. A sensing element comprised of two metals having different coefficients o f t h e r m a l e x p a n s i o n arranged so that the effect will be deflection in one direction when heated and in the opposite direction when cooled. (b) Electrical Conductivity. A line-type or spot-type sensing element whose resistance varies as a function of temperature. (c) Fusible Alloy. A sensing element of a special compo, sition (eutectic) metal, which melts rapidly at the rated temperature. (d) Heat-Sensitive Cable. A line-type device whose sensing element comprises, in one type, two current-carrying wires held separated by a heat-sensitive insulation that softens at the rated temperature, thus allowing the wires to make electrical contact. In another type, a single wire is centered in a metallic tube and the intervening space is filled with a substance that, at a critical t e m p e r a t u r e , becomes conductive, thus establishing electrical contact between the tube and the wire.

(e) Liquid Expansion. A sensing element comprising a liquid capable of marked expansion in volume in response to temperature increase.

3-2.3.1 A rate-of-rise detector is a device that will respond when the t e m p e r a t u r e rises at a rate exceeding a predetermined amount. 3-2.3.2 Typical examples are: (a) Pneumatic Rate-of-Rise Tubing. A line-type detector comprising small diameter tubing, usually copper, which is installed on the ceiling or high on the walls t h r o u g h o u t the detected area. T h e tubing is terminated in a detector unit containing d i a p h r a g m s and associated contacts set to actuate at a p r e d e t e r m i n e d pressure. T h e system is sealed except for calibrated vents that compensate for normal changes in temperature. (b) Spot-type Pneumatic Rate-of-Rise Detector. A device consisting of an air chamber, d i a p h r a g m , con.tacts, and compensating vent in a single enclosure. T h e principle of operation is the same as that described in 3-2.3.2(a). (c) Thermoelectric Effect Detector. A device whose sensing element comprises a thermocouple or thermopile unit that produces an increase in electric potential in response to an increase in temperature. This potential js monitored by associated control equipment, and an alarm is initiated when the potential increases at an abnormal rate. (d) Electrical Conductivity Rate-of-Change Detector. A linetype sensing element whose resistance changes due to a change in temperature. T h e rate of change of resistance is monitored by associated control equipment, and an alarm is initiated when the rate of increase exceeds a preset value.

3-3 Temperature Classification. 3-3.1 Heat detectors of the f i x e d - t e m p e r a t u r e or ratecompensated spot-pattern type shall be classified as to the t e m p e r a t u r e of operation and marked with the a p p r o p r i ate color code. (See Table 3-3.1.) 3-3.1.1 Where the overall color of a detector is the same as the color code marking required for that detector, either one of the following arrangements, applied in a contrasting color and visible after installation, shall be employed:

[See 3-2.3.2(c).] In these cases, the manufacturer's recommendations shall be followed for appropriate alarvn point and spacing. NOTE: Table 3-5.1.2 provides for spacing modifications to take into account different ceiling heights for generalized fire conditions. An alternative design method, which allows a designer to take into account ceiling height, fire size, and ambient temperature, is provided in Appendix C.

3-5.2* Solid Joist Construction. T h e spacing of heat detectors, when measured at right angles to the solid joists, shall not exceed 50 percent of the smooth ceiling spacing allowable u n d e r 3-5.1 and 3-5.1.1. (See Figure A-3-5.2.) 3-5.3* Beam Construction. It shall be t r e a t e d as a smooth ceiling if the beams project no more than 4 in. (100 mm) below the ceiling. If the beams project more than 4 in. (100 ram) below the ceiling, the spacing of spot-type heat detectors at right angles to the direction of beam travel shall be not more than two-thirds the smooth ceiling spacing allowable u n d e r 3-5.1 and 3-5.1.1.

tosensitive sensor. When smoke particles enter the light path, some of the light is scattered by reflection and refraction onto the sensor, causing the detector to respond. 4-2.2.1 Photoelectric light scattering detection is more responsive to visible (size more-than one micron) particles produced by most smoldering fires. It is somewhat less responsive to the smaller particles typical of most flaming fires. It is also less responsive to black smoke. 4-2.2.2 Smoke detectors utilizing the light scattering principle are usually of the spot type.

4-1.1" The purpose of this chapter is to provide information to assist in the design and installation of reliable early warning smoke detection systems for protection of life and property.

4-2.3* Photoelectric Light Obscuration Smoke Detection. In a photoelectric light obscuration smoke detector, the loss of light transmission between a light source and a photosensitive sensor is monitored. When smoke particles are introduced in the light path, some of the light is scattered and some absorbed, thereby reducing the light reaching the receiver, causing the detector to respond.

4-1.2 This chapter covers general area application of smoke detectors in ordinary indoor locations.

4.2.3.1 The response of photoelectric light obscuration smoke detectors is usually not affected by the color of smoke.

4-1.2.1 For information on use of smoke detectors for control of smoke spread, refer to Chapter 9 of this standard.

4-2.3.2 Smoke detectors utilizing the light obscuration principle are usually of the line type. These detectors are commonly called projected beam smoke detectors.

4-1.2.2 For additional guidance in the application of smoke detectors for flaming fires of various sizes and growth rates in areas of various ceiling heights, refer to Appendix C, Section C-5.

4-2.4 Cloud Chamber Smoke Detection. A smoke detector utilizing the cloud chamber principle is usually of the sampling type. An air p u m p draws a sample of air from the protected areas into a high humidity chamber within the detector. After the humidity of the sample has been raised, the pressure is lowered slightly. If smoke particles are present, the moisture in the air condenses on them, forming a cloud in the chamber. The density of this cloud is then measured by a photoelectric principle. When the density is greater than a predetermined level, the detector responds.

4-1 General.

4-1.3" Smoke detectors shall be installed in all areas where required either by the appropriate NFPA standard or by the authority having jurisdiction.

4-2 Principles of Detection. 4-2.1 Ionization Smoke Detection. An ionization smoke detector has a small amount of radioactive material that ionizes the air in the sensing chamber, thus rendering it conductive and permitting a current flow through the air between two charged electrodes. This gives the sensing chamber an effective electrical conductance. When smoke particles enter the ionization area, they decrease the conductance of the air by attaching themselves to the ions, causing a reduction in mobility. When the conductance is less than a predetermined level, the detector responds. 4-2.1.1 Ionization detection is more responsive to invisible (size less than one micron) particles produced by most flaming fires. It is somewhat less responsive to the larger particles typical of most smoldering fires. 4-2.1.2 Smoke detectors utilizing the ionization principal are usually of the spot type.

4-2.2* Photoelectric Light Scattering Smoke Detection. In a photoelectric light scattering smoke detector, a light source and a photosensitive sensor are so arranged that the rays from the light source do not normally fall on the pho-

4-3 Classification. 4-3.1 Spot-type Smoke Detectors. S p o t - t y p e s m o k e detectors shall be marked with their normal production sensitivity (percent per foot obscuration), measured as required by the listing. The production tolerance around the normal sensitivity shall also be indicated. 4-3.1.1 Smoke detectors that have provision for field adjustment of sensitivity shall have an adjustment range of not less than 0.6 percent/ft obscuration, and the adjusting means shall be marked to indicate its nominal factory calibration position.

4-4 Location and Spacing. 4-4.1" General. T h e location and spacing o f smoke detectors shall result from an evaluation based on engineering j u d g m e n t supplemented by the guidelines detailed in this standard. Ceiling shape and surfaces, ceiling height, configuration of contents, burning characteristics of combustible material present, and ventilation are some of the conditions that shall be considered.

If the projected light beams of line-type detectors run p e r p e n d i c u l a r to the joists, no spacing reduction is necessary; however, if the projected light beanas are parallel to the.joists, thc spacing between light beams shall be reduced. Spot-type dctcctors shall be m o u n t e d on the bottom of the joists. (Also see

AUTOMATIC FIRE DETECTORS

4-4.8.2 Shed. Detectors shall first be spaced and located within 3 ft (0.9 m) of the high side of the ceiling, measured horizontally. T h e n u m b e r and spacing of additional detectors, if any, shall be based on the horizontal projection of the ceiling. (See Figure A-3-5.4.2.) 4-4.9 Raised Floors and Suspended Ceilings. In underfloor spaces and above ceiling spaces that are not HVAC plenums, detector spacing shall be in accordance with Seeuon 4-4. 4-4.10 Partitions. W h e r e partitions extend u p w a r d to within 18 in. (460 ram) of the ceiling, they will not influence the spacing. Where the partition extends to within less than 18 in. (460 ram) of the ceiling, the effect of smoke travel shall be considered in reduction of spacing. 4-5 Heating, Ventilating, and Air Conditioning (HVAC). 4-5.1" In spaces served by air handling systems, detectors shall not be located where air from supply diffusers could dilute smoke before it reaches the detectors. Detectors shall be located to intercept the air flow toward the return air opening(s). This may require additional detectors, since placing detectors only near return air openings may leave the balance of the area with inadequate protection when the air handling system is shut down. T h e detector manufacturer shall be consulted before installation of detectors. 4-5.2 In spaces u n d e r floors and above ceiling spaces that are used as HVAC plenums, detectors shall be listed to be compatible with air velocities present. Detector spacings and locations shall be selected based upon anticipated airflow patterns and fire type. 4-5.2.1 Detectors placed in environmental air ducts or plenums shall not be used as a substitute for open area I detectors. (See Chapter 9 and "FableA-4-6.1.4.) Smoke may not be drawn into the duct or plenums when the ventilating system is shut down. Further, when the ventilating system is operating, the detector(s) may be less responsive to a fire condition in the room of fire origin due to dilution by clean air.

4-6 Special Considerations. 4-6.1 General. T h e selection and installation of smoke detectors shall take into consideration both the design characteristics of the detector and the areas into which the detectors will be installed so as to prevent false operation or nonoperation after installation. Some of the considerations are as follows. [4-6.1.1" T h e installation of smoke detectors shall take into consideration the e n v i r o n m e n t a l condition of the area(s). Smoke detectors are intended for installation in areas where the normal ambient conditions are not likely to: (a) Exceed 100°F (38°C) or fall below 32°F (0°C); or (b) Exceed 93 percent relative humidity; or (c) Exceed air velocity of 300 fpm (1.5 mps).

Exception: Detectors .specifically designed for use in ambients exceeding the above limits and listed for the temperature, humidity, and air velocity conditions expected. 14-6.1.2" T o avoid u n w a n t e d a l a r m s , the location o f smoke d e t e c t o r s shall take into c o n s i d e r a t i o n n o r m a l sources of smoke, moisture, dust or fumes, and electrical or mechanical influences. 4-6.1.3 Detectors shall not be installed until after the construction cleanup of all trades is complete and final.

Exception: Where required by the authority having jurisdiction for protection during construction. Detectors that have been installed prior to final cleanup by all trades shall be cleaned or replaced p e r Section 8-4.

4-6.2 Spot-type Detectors. 4-6.2.1 Smoke detectors having a fixed t e m p e r a t u r e element as part of the unit shall be selected in accordance with Table 3-3.1 for the m a x i m u m ceiling t e m p e r a t u r e that can be expected in service. 4-6.2.2* ered by shall be or from entry of

Air holes in the back of a detector shall be cova gasket, sealant, or equivalent, and the detector m o u n t e d so that air-flow from inside the housing the p e r i p h e r y of the housing will not prevent the smoke d u r i n g a fire or test condition.

4-6.3 Projected Beam-type Detectors. 4-6.3.1 Projected beam-type detectors and mirrors shall be firmly m o u n t e d on stable surfaces, so as to prevent false or erratic operation due to movement. T h e beam shall be so designed that small a n g u l a r movements of the light source or receiver do not prevent operation due to smoke and do not cause false alarms. Ordinarily, movement of I/4 degree shall be tolerated (1/2 degree circular included angle). 4-6.3.2 Since the projected beam-type unit will not operate for alarm but will give a trouble signal (see A-4-2.3) when the light-path to the receiver is abruptly i n t e r r u p t e d or obscured, the light-path shall be kept clear of opaque obstacles at all times. 4-6.4* H i g h Rack Storage. (See Figures A-4-6.4(a) and A-4-6.4(b).) Detection systems are often installed in addition to suppression systems. Where smoke detectors are installed for early warning in high rack storage areas, it shall be necessary to consider installing detectors at several levels in the racks to ensure quicker response to smoke. W h e r e detectors are installed to actuate a suppression system, see NFPA 231C, Standard for Rack Storage of Materials.

4-6.5 High Air Movement Areas. 4-6.5.1 General. T h e p u r p o s e and scope of this section are to provide location and spacing guidance for smoke detectors in high air movement areas for early warning of fire.

FLAMESENSING FIRE DETECTORS

Exception: Detectorsprovided for the control of smoke spread are covered by the requirements of Chapter 9. [4-6.5.2 A c c e p t a n c e Criteria. Detector response shall be determined by the authority having jurisdiction, which may utilize the detector manufacturer's recommendations. 4-6.5.3 Location. Smoke detectors shall not be located directly in the air stream of supply registers. (See A-4-5.1.) I 4-6.5.4 Spacing. Smoke detector spacing depends upon the movement of air within the room (including both supplied and recireulated air), which can be designated as minutes per air change or air changes per hour. Except where otherwise accepted by the authority having jurisdiction, spacing shall be in accordance with Figures 4-6.5.4(a) and (b). A projected beam smoke detector may be used in place of each row of spot detectors at the reduced spacing.

AUTOMNI'IC FIRE DETECTORS

5-2.1.5 Flame Detector Sensitivity. T h e d i s t a n c e at which the detector will detect a fire of specified size and fuel within a given time frame. 5-2.1.6" Spark.

A moving ember.

5-2.1.7 Spark/Ember Detectors. R a d i a n t e n e r g y fire detectors that are designed to detect sparks, embers, or both. These devices are normally intended to operate in dark environments and operate in the infi'ared part of the spectrum. 5-2.1.8 Spark/Ember Detector Sensitivity. T h e n u m b e r of watts (or fractions of watts) of radiant power from a point source radiator, applied as a unit step signal at the wavelength of maximum detector sensitivity, that are necessary to produce an alarm signal from the detector within the specified response time.

5-2.1.9"

W a v e l e n g t h . All r a d i a n t e n e r g y can be described as a wave having a wavelength, the distance between the peaks of a sinusoidal wave. Wavelength is analogous to color in the visible part of the spectrum and serves as the unit of measure for distinguishing between different parts of the spectrum. Wavelengths are measured in microns (p.), nanometers (nM), or angstroms (~). 5-2.2 Operating Principles of Flame Detectors. 5-2.2.1 Ultraviolet flame detectors typically use a vacuum p h o t o d i o d e Geiger-Muller tube to detect the ultraviolet radiation that is p r o d u c e d by a flame. T h e p h o t o d i o d e allows a burst of c u r r e n t to flow for each ultraviolet photon that hits the active area of the tube. When the n u m b e r of current burst per unit time reaches a p r e d e t e r m i n e d level, either the detector or its control initiates an alarm. 5-2.2.2 A single wavelength infrared flame detector uses one of several different types of photocells to detect the infrared emissions in a single narrow wavelength band that are produced by a flame. These detectors generally include provisions to minimize alarms from commonly occurring infrared sources such as incandescent lighting or sunlight. 5-2.2.3 An ultraviolet/infrared (UV/IR) flame detector senses ultraviolet radiation using a vacuum p h o t o d i o d e tube and a selected wavelength of infrared radiation (usually the 4.35 micron, carbon dioxide band) using a photocell and uses the combined signal to indicate a fire. These detectors require both types of radiation to be present before an alarm signal is rendered.

5-2.2.4 A m u h i p l e wavelength infrared (IR/IR) flame detector senses radiation at two or more narrow bands of wavelengths in the infrared spectrum, using at least one wavelength as a background or reference band (usually the 3.8 micron or 5.6 micron band) and at least one wavelength to sense the flame emissions (usually the 4.35 micron, carbon dioxide band). These detectors compare the emissions between the reference band and the sample band electronically and r e n d e r a signal when the relationship between the two bands indicates a fire.

5-2.3 Operating Principles of Spark/Ember Detectors. 5-2.3.1 A s p a r k / e m b e r sensing detector usually uses a solid state p h o t o d i o d e or phototransistor to sense the radiant energy emitted by embers, typically between 0.5 and 2.0 microns in the visible and infrared portion of the spectrum, in normally dark environments. These detectors can be m a d e e x t r e m e l y sensitive (microwatts), a n d t h e i r response times can be made very short (microseconds).

5-3 Fire Characteristics and Detector Selection. 5-3.1" T h e type and quantity of radiant energy-sensing fire detectors will d e p e n d upon the hazard including the burning characteristics of the fuel, the fire growth rate, the environment, the ambient conditions, and the capabilities of the extinguishing m e d i a and equipment.

5-4 Spacing Considerations. 5-4.1 General Rules. 5-4.1.1" Radiant energy-sensing fire detectors shall be employed consistent with the listing or approval and the inverse square law which defines the fire size vs distance curve for the detector. 5-4.1.2 Detectors shall be used in sufficient quantity and positioned such that no point requiring detection in the hazard area is obstructed or outside the field of view of at least one detector. 5-4.1.3 T h e environment and ambient conditions anticipated in the area to be protected will impact on the choice of detector. All detectors have limitations on the range of ambient temperatures over which they will r e s p o n d consistent with t h e i r tested or a p p r o v e d sensitivities. T h e designer should make certain that the detector is compatible with the range of ambient t e m p e r a t u r e s anticipated in the area in which it is installed. In addition, rain, snow, and ice are all optically opaque at both uhraviolet and infrared wavelengths. Where applicable, provisions should be made to protect the detector from accumulations of these materials on the optical surfaces.

5-4.2 Spacing Considerations for Flame Detectors. 5-4.2.1" T h e location and spacing of detectors shall be the result of an engineering evaluation, taking into consideration: (a) T h e size of the fire that is to be detected. (b) T h e fuel involved. (c) T h e sensitivity of the detector. (d) T h e distance between the fire and the detector. (e) T h e radiant energy absorption of the atmosphere. (t) T h e presence of extraneous sources of radiant emissions. (g) T h e purpose of the detection system. 5-4.2.2 T h e designer shall define the size of the flaming fire of given fuel that is to be detected.

5-5 Field of View Considerations. 5-5.1 Since flame detectors are essentially line-of-sight devices, special care shall be taken to ensure that their ability to respond to the required area of fire in the zone that is to be protected will not be unduly compromised by the p r e s e n c e of i n t e r v e n i n g s t r u c t u r a l m e m b e r s o r o t h e r opaque objects or materials. 5-5.2 T h e overall situation shall be reviewed fi'equently to ensure that changes in structural or usage conditions that could interfere with fire detection capabilities are r e m e d i e d promptly.

5-6 Other Considerations. 5-6.1 Flame detectors shall have such spectral and optical response capabilities that they will initiate action from the specific spectral emission that occurs when the particular fuel(s) of the protected hazard is afire. 5-6.2 Detectors shall be designed, protected, or serviced so that interference with reception of radiation will not Occur, preventing operation. 5-6.3 Where necessary, detectors shall be shielded or otherwise a r r a n g e d to prevent action fi'om unwanted radiant energy. 5-6.4 Where used in o u t d o o r applications, detectors shall be shielded in a fashion to prevent diminishing sensitivity by rain, snow, etc., and yet allow a clear field of vision of the hazard area.

AUTOMATIC FIRE DETECTORS

6-2 Operating Principles.

6-3.6 Beam Construction.

6-2.1 Semiconductor. Fire-gas detectors of the semiconductor type respond to either oxidizing or reducing gases by creating electrical changes in the semiconductor. T h e s u b s e q u e n t conductivity c h a n g e of the s e m i c o n d u c t o r causes actuation.

6-3.6.1 Ceiling construction where beams are 8 in. (200 mm) or less in depth shall be considered equivalent to a smooth ceiling. (See also A-4-4.1.2.)

6-2.2 Catalytic Element.

Fire-gas detcctors of the catalytic element type contain a material that, in itself, remains unchanged but accelerates the oxidation of combustible gases. T h e resulting t e m p e r a t u r e rise of the element causes actuation.

6-3.6.2 If beams are over 8 in. (200 mm) in depth, the spacing of spot-type detectors in the direction p e r p e n d i c u lar to the beams shall be reduced. (See also A-4-4.1.2.) 6-3.6.3* If the beams exceed 18 in. (460 mm) in depth and are more than 8 ft (2.4 m) on centers, each bay shall be treated as a separate area requiring at least one spottype detector.

6-3 Location and Spacing. 6-3.7 Sloped Ceilings. 6-3.1" G e n e r a l . T h e location a n d spacing of fire-gas detectors shall result from an evaluation based on engineering j u d g m e n t s u p p l e m e n t e d by the guidelines detailed in this standard. Ceiling shape and surfaces, ceiling height, configuration of contents, burning characteristics of combustible material present, and ventilation are some of the conditions that shall be considered.

6-3.7.1 P e a k e d . D e t e c t o r s shall first be s p a c e d a n d located within 3 ft (0.9 m) of the peak, measured horizontally. T h e n u m b e r and spacing of additional detectors, if any, shall be based on the horizontal projection of the ceiling. (See Figure A-3-5.4.1.)

6-3.1.1 Where the intent is to provide protection from a specific hazard, the detector(s) may be installed closer to the hazard in a position where the detector will readily intercept the fire gases.

6-3.7.2 Shed. Detectors shall first be spaced and located within 3 ft (0.9 m) of the high side of the ceiling, measured horizontally. T h e n u m b e r and spacing of additional detectors, if any, shall be based on the horizontal projection of the ceiling. (See Figure A-3-5.4.2.)

6-3.1.2 Stratification. T h e possible effect of gas stratification at levels below the ceiling shall also be considered. (See

6-3.8 Suspended Ceilings.

(See 2-7.4.)

A-4-4.1.2.) 6-3.2 Spot-type fire-gas detectors shall be located on the ceiling not less than 4 in. (100 mm) from a sidewall to the near edge, or if on a sidewall, between 4 in. and 12 in. (100 mm and 300 mm) down from the ceiling to the top of the detector. (See Figure A-3-4.1.)

Exception No. 1: See 6-3.1.2. Exception No. 2: In the case of solid joist construction, detectors shall be mounted at the bottom of the joists. Exception No. 3: In the case of beam construction where beants are less than 12 in. (300 ram) in depth and less than 8 ft (2.4 m) on center, detectors may be installed on the bottom of beams. 6-3.3* Each sampling p o r t of a sampling-type fire-gas detector shall be treated as a spot-type detector for the purpose of location and spacing.

6-3.4 Smooth Ceiling Spacing. 6-3.4.1 Spot-type Detectors. On smooth ceilings, spacing of 30 ft (9.1 In) may be used as a guide. In all cases, the manufacturer's recommendations shall be followed. Other spacing may be used d e p e n d i n g on ceiling height, varying conditions, or response requirements. 6-3.5 Solid Joist Construction.

(SeeA-4-4.6.)

6-3.9 P a r t i t i o n s . W h e r e partitions e x t e n d u p w a r d to within 18 in. (460 mm) of the ceiling, they will not influence the spacing. Where the partition extends to within less than 18 in. (460 mm) of the ceiling, the effect on gas travel shall be considered in reduction of spacing.

6-4 Heating, Ventilating, and Air Conditioning (HVAC). 6-4.1" In spaces served by air handling systems, detectors shall not be located where air from supply diffusers could dilute fire gases before they reach the detectors. Detectors shall be located to intercept the airflow toward the return air opening(s). 6-4.2 In spaces u n d e r floors and above ceiling spaces used as HVAC plenums, detectors shall be listed to be compatible with air velocities present. Detector spacings and locations shall be selected based on anticipated air-flow patterns and fire types. 6-4.2.1 Detectors placed in environmental air ducts or plenums shall not be used as a substitute for open area detectors. Fire gases may not be drawn into the duct or plenums when the ventilating system is shut down. Further, when the ventilating system is operating, the detector(s) may be less responsive to a fire condition in the room of fire origin due to dilution by clean air. (See Chapter 9 and

6-3.5.1 Ceiling construction in which joists are 8 in. (200 mm) or less in depth shall be considered equivalent to a smooth ceiling. (See also A-4-4.1.2.)

OTHER FIRE DETECTORS/INSPECTIONS,TESTS, AND MAINTENANCE be installed to prevent false operation or n o n o p e r a t i o n after installation. Some of the considerations are as follows. 6-5.1.1 Fire-gas detectors may alarm in nonfire situations due to certain h u m a n activities.

A-5-3.1 T h e radiant energy from a flame or spark/ember Is comprised of emissions in various bands of the ultraviolet, visible, and infrared portions of the spectrum. T h e relative quantities of radiation emitted in each part of the spectrum are d e t e r m i n e d by the fuel chemistry, the temperature, and the rate of combustion.

l e n g t h o f light b e i n g e m i t t e d from a flame a n d the combustion chemistry producing the flame. Specific subatomic, atomic, and molecular events yield radiant energy of specific wavelengths. For example, uhraviolet photons are emitted as the result of the complete loss of electrons or very large changcs in electron energy levels. During combustion, molecules are violently torn a p a r t by the chemical reactivity of oxygen, and electrons are released in the process, recombining at drastically lower energy levels, thus giving rise to ultraviolet radiation. Visible radiant energy is generally the result of smaller changes in electron energy levels within the molecules of fuel, flame intermediates, and p r o d u c t s of combustion. I n f r a r e d radiation comes fi'om the vibration of molecules or parts of molecules when they are in the superheated state associated with combustion. Each chemical c o m p o u n d exhibits a g r o u p of wavelengths at which it is resonant. These wavelengths constitute the chemical's IR spectrum, which is usually unique to that chemical.

A-5-2.1.1 Class A and D combustibles will burn as embers under conditions where the typical flame associated with fire does not necessarily exist. This "glowing combustion" yields radiant emissions in radically different parts of the radiant energy spectrum than does flaming combustion. Specialized detectors, specifically designed to detect those emissions, should be used in applications where this type of combustion is expected. In general, flame detectors are not intended for the detection of embers: A-5-2.1.6 T h e o v e r w h e l m i n g majority of a p p l i c a t i o n s involving the detection of Class A and D combustibles using radiant energy sensing detectors involve the transport of particulate solid materials t h r o u g h pneumatic conveyance ducts or mechanical conveyors. It is c o m m o n in the industries that include such hazards to call a moving piece of burning material a "spark" and systems for the detection of such fires "spark detection systems." A-5-2.1.9 T h e concept of wavelength is extremely important in selecting the p r o p e r detector for a particular application. T h e r e is a precise interrelation between the wave-

Almost all materials that participate in flaming combustion will emit ultraviolet radiation to some degree d u r i n g flaming combustion, whereas only carbon-containing fuels will emit significant radiation at the 4.35 micron (carbon dioxide) band used by many detector types to detect a flame. The radiant energy emitted from an e m b e r is determined primarily by the fuel t e m p e r a t u r e (Plank's Law o f Emissions ) and the emissivity of the fuel. Radiant energy from an e m b e r is p r i m a r i l y i n f r a r e d a n d , to a lesser degree, visible in wavelength. In general, embers do not emit ultraviolet energy in significant quantities (0.1 percent of total emissions) until the e m b e r achieves t e m p e r a t u r e s of 2000 K (1727°C or 3240°F). In most cases, the emissions will be included in the band of 0.8 to 2.0 microns, corresponding to t e m p e r a t u r e s of approximately 750°F (398°C) to 1830°F (1000°C). Most radiant energy detectors have some form of qualification circuitry within them that uses time to help distinguish between spurious, transient signals and legitimate fire alarms. These circuits become very i m p o r t a n t when one considers the anticipated fire scenario and the ability of the detector to r e s p o n d to that anticipated fire. For example, a detector that utilizes an integration circuit or a timing circuit to respond to the flickering light from a fire may not respond well to a deflagration resulting from the ~gnition of accumulated combustible vapors and gases, or where the fire is a spark that is traveling up to 100 meters ~er second past the detector. U n d e r these circumstances, a

APPENDIX A detector that has a high speed response capability would be most a p p r o p r i a t e . On the o t h e r hand, in applications where the d e v e l o p m e n t of the fire will be slower, a detector that utilizes time for the confirmation of repetitive signals would be appropriate. Consequently, the fire growth rate should be considered in selecting the detector. T h e detector performance should be selected to respond to the anticipated fire: T h e radiant emissions are not the only criterion to be considered. T h e medium between the anticipated fire and the detector is also very important, Different wavelengths of radiant energy are absorbed with varying degrees of efficiency by materials suspended in the air or by those that may accumulate on the optical surfaces of the detector. Generally, aerosols and surface deposits reduce the sensitivity of the detector. T h e detection technology utilized should take into account those normally occurring aerosols and surface deposits to minimize the reduction of system response between maintenance intervals. Note that the smoke evolved from the combustion of middle and heavy fraction petroleum distillates is highly absorptive in the ultraviolet end of the spectrum. Where using this type of detection, the system should be designed to minimize the interference of smoke on the response of the detection system. T h e environment and ambient conditions anticipated in the area to be protected will impact on the choice of detector. All detectors have limitations on the range of ambient temperatures over which they will respond consistent with their tested or a p p r o v e d sensitivities. T h e designer should make certain that the detector is compatible with the range of ambient temperatures anticipated in the area in which it is installed. In addition, rain, snow, and ice are all optically o p a q u e at both u l t r a v i o l e t a n d i n f r a r e d wavelengths. Where applicable, provisions should be made to protect the detector from accumulations of these materials on the optical surfaces. A-5-4.1.1 All optical detectors respond pursuant to the following theoretical equation:

T h e curve defines the maximum distance at which the detector consistently detects a fire of defined size and fuel. Detectors should only be employed in the shaded area beneath the curve. U n d e r the best of conditions, with no a t m o s p h e r i c absorption, the radiant power reaching the detector is reduced by a factor of 4 if the distance between the detector and the fire is doubled. For the consumption of the atmospheric extinction, the exponential term, Zeta (~) is a d d e d to the equation. Zeta (~) is a measure of the clarity of the air at the wavelength u n d e r consideration. Zeta (~) will be affected by humidity, dust, and any other contaminants in the air that are absorbant at the wavelength in question. Zeta (~) generally has values between -.001 and -.1. A-5-4.2.1 Extraneous sources of radiant emissions that have been identified as interfering with the stability of flame detectors include: (a) sunlight (b) l i g h t n i n g .

A°5-4.2.4 Virtually all radiant energy sensing detectors exhibit some kind of "fuel specificity." Different fuels when b u r n e d at uniform rates (joules/sec or watts) will emit different levels of radiant power in the ultraviolet, visible, and infrared portions of the spectrum. U n d e r free-burn conditions, a fire of given surface area but of different fuels will burn at different rates (joules/sec or watts) and emit varying levels of radiation in each of the major portions of the spectrum. Most r a d i a n t e n e r g y d e t e c t o r s d e s i g n e d to detect flame are qualified based upon a defined fire u n d e r specific conditions. Where employing these detectors for fuels other than the defined fire, the designer should make certain that the a p p r o p r i a t e adjustments to the m a x i m u m distance between the detector and the fire are made consistent with the fuel specificity of the detector. A-5-4.2.6 T h e means by which this requirement has been satisfied include: (a) lens clarity monitoring and cleaning when a contaminated lens signal is r e n d e r e d , or (b) lens air purge. A-5-4.3.1 Spark/ember detectors are installed primarily to detect sparks and embers that may, if allowed to continue to burn, precipitate a much larger fire or explosion. S p a r k / e m b e r detectors are typically m o u n t e d on some form of conveyor monitoring the fuel as it passes by. Usually, it is necessary to enclose the portion of conveyor where the detectors are located as these devices generally require a dark environment. Extraneous sources of radiant emissions that have been identified as interfering with the stability of spark/ember detectors include: (a) ambient light (b) radio frequency interference (c) electrostatic discharge in the fuel stream

A-6-1.1.1 Many gases may be p r o d u c e d by a fire. Fire-gas detectors are instruments that are triggered into alarm by one or more fire gases. Fire-gas detectors need not be able to differentiate a m o n g the various fire gases. D e p e n d i n g on the material being b u r n e d and the oxygen supply available, the quantity and composition of gases given off can vary greatly. If o r d i n a r y cellulosic material such as wood or p a p e r is b u r n e d with an abundance of oxygen, the gases given off are primarily carbon dioxide and water vapor. If, however, the same material is b u r n e d or smolders with a limited supply of oxygen, a host of additional gases will be evolved. A-6-3.1 Fire-gas detectors d e p e n d on fire gases reaching the sensing element. W h e n sufficient c o n c e n t r a t i o n is present, operation is obtained. Since the detectors are usually m o u n t e d on o r n e a r the ceiling, r e s p o n s e time d e p e n d s on the nature of the fire. A hot fire will drive fire gases up to the ceiling more rapidly. A smoldering fire produces little heat and, therefore, the detection time will be increased.

APPENDIX A

A-6-3.3 Gas transport to the sensor of a fire-gas detector may occur by diffusion where migration results fi'om concentration gradients or by sampling if pumps, fans, or aspirators are employed. A-6-3.6.3 Location and spacing of fire-gas detectors should consider beam depth, ceiling height, beam spacing, and anticipated fire type and location. For ceiling configurations where mixing of air into beam pockets is inhibited by ventilation systems, detectors will perform better if installed on the bottom of beams. To detect flaming fires (strong plumes), detectors should be installed as follows: (a) If the ratio of the beam depth, D, to ceiling height, H, (D/H) is greater than 0.10 and the ratio of beam spacing, W, to ceiling height (W/H) is greater than 0.40, detectors should be located in each beam pocket. (b) If either ratio of beam depth to ceiling heigl-it (D/H) is less than 0.10, or the ratio of beam spacing to ceiling height (W/H) is less than 0.40, detectors should be installed on the bottom of the beams. To detect smoldering fires (weak or no plumes), detectors should be instfilled as follows: (c) If air mixing into beam pockets is good (e.g. air-flow parallel to long beams) and condition (a) exists as above, a detector should be located in each beam pocket. (d) If air mixing into beam pockets is limited, or condition (b) exists as above, detectors should be located on the bottom of the beams. A-6-4.1 Detectors should not be located in a direct airflow nor closer than 3 ft (900 ram) from an air supply diffuser.

72E-39

A-8-2 Factors to be considered for inspection and tests of detectors include: (a) Operational range of voltage, current, and signaling technique of the detector with respect to the control equipment. (b) Polarity of power connection to the detector• (c) Integ~:ity of electrical connections. (d) Integrity of mechanical connections• (e) Mechanical support. A-8-2.3.1 T h e rate-of-rise element of a combination detector can also be tested by cooling the detector and then causing it to rise in temperatur& This will generally activate the rate-of-rise element without risk of damage to the nonrestorable fixed temperature element. A-8-2.4.1.1 Aerosols should be used in accordance with the detector manufacturer's instructions to avoid damage and contamination to the detector. If aerosols are sprayed directly into the detector at less than the recommended distance, or if aerosols are sprayed for too long a time, an excessive amount of aerosol may cause damage to the detector. A-8-3.1 Regardless of the type of detectors in use, the following detectors should either be replaced or representative samples sent to a testing laboratory or the manufacturer for testing: (a) Detectors on systems that are being restored to service after a period of disuse. (b) Detectors that are perceptibly corroded. (c) Detectors that have been painted in the field, unless they are of a type found by the testing laboratory to be unaffected by paintingl

A-6-5.1.3 Product listing standards include tests for temporary excursions beyond normal limits. In addition to temperature, humidity, and velocity variations, fire-gas detectors should operate reliably u n d e r such c o m m o n environmental conditions as mechanical vibration, electrical interference, and other environmental influences. These conditions are also included in tests conducted by the listing agencies.

(f) Detectors on circuits that have been subjected to surges'by overvoltages or lightning damage.

A-8-1.3.2 Examples of qualified personnel include but are not limited to:

(g) Detectors that are subjected to other conditions that may permanently affect their operation, such as grease or other deposits or corrosive atmospheres.

(d) Detectors that have been cleaned of paint. (e) Detectors that have been subjected to mechanical injury or similar abuse.

(a) Factory trained and certified. (b) National Institute for Certification in Engineering Technologies certified.

(c) International Municipal Signaling Association Certified. (d) Certified by State or Local Authority. (e) Trained and qualified personnel employed by an organization listed by a nationally recognized Testing Laboratory for the servicing of Fire Protective Signaling System.

A-8-3.4.2 In the determination of baseline detector sensitivity, the detectors should be isolated from the installed environmental factors (i.e., air velocity) that may affect the measurement. Detectors installed in environments subject to large amounts of dust and dirt or in areas recently renovated require more frequent sensitivity testing. In lieu of environmental isolation for test, analog type detectors may utilize listed control equipment that automatically compensates for environmental conditions and maintains the detector "sensitivity" (alarm point definition) within acceptable limits.

A U T O M N [ ' I C FIRE DETECTORS

There is a large population of installed smoke detectors that were manufactured in compliance with previous product standards that did not require a means for testing sensitivity within an acceptable listed range. It is the intent of this s t a n d a r d that these detectors need not be tested against current product standards.

The detectors should be installed up to 12 in. (0.3 m) in fi'ont of or behind the o p e n i n g and spaced according to the following o p e n i n g dimensions: (1)

In order to determine the effects of the e n v i r o n m e n t on the detector, a measurement of detector sensitivity in the installed e n v i r o n m e n t should be considered. A-8-4.1 Accumulation of dust and dirt adversely affect detector performance. Detectors that are visibly dirty or have significantly changed in sensitivity, should be cleaned. If after five years of field service, a detector has not been cleaned, it should be cleaned for the purpose of preventative maintenance to minimize false alarms. In an exceptionally clean e n v i r o n m e n t the time interval may be extended. Manufacturer's instructions may detail detector maintenance methods such as vacuuming to remove loose dirt and insects, and washing to remove greasy deposits. In lieu of these cleaning methods, the manufacturer may provide cleaning servce at the factory or field locations.

B-I-2 Generally, height is the most i m p o r t a n t single dimension where ceiling heights exceed 16 ft (4.9 m).

B-I-3 As smoke and heat rise from a fire, they tend to spread in the general form of an inverted cone. Therefore, the concentration within the cone varies inversely as a variable exponential function of the distance from the source. This effect is very significant in the early stages of a fire as the angle of the cone is wide. As a fire progresses in intensity, the angle of the cone narrows and the significance of the effect of height is lessened. B-I-4 H i g h Ceilings. As the ceiling height increases, a larger-size fire is required to actuate the same detector in the same time. In view of this, it is mandatory that the designer of a fire detection system calling for heat detectors consider the size of the fire and rate of heat release that may be permitted to develop be[bre detection is ultimately obtained. B-l-5 The most sensitive detectors suitable [br the maximum ambient t e m p e r a t u r e at heights above 30 ft (9.1 m) should be employed.

B-l-6 Spacing r e c o m m e n d e d by testing laboratories for the location of detectors is an indication of their relative sensitivity. This applies with each detection principle; however, detectors o p e r a t i n g on various physical principles have different inherent sensitivities to different types of fires and fuels.

B-l-7 Reduction of listed spacing may be required fro. any of the following purposes: (a) Faster response of the device to a fire. (b) Response of the device to a smaller fire. (c) Accommodation to room geometry. (d) Other special considerations, such as air movement, or ceiling or other obstructions.

C-1 Introduction. C-I-1 Scope. This appendix provides information intended to s u p p l e m e n t NFPA 72E, Standard for Automatic Fire Detectors, and includes a p r o c e d u r e for deternfining heat detector spacing based on the size and rate of growth of fire to be detected, various ceiling heights, and ambient temperature. T h e effects of ceiling height and the size and rate of growth of a flaming fire on smoke detector spacing are also treated. A p r o c e d u r e for analyzing the response of existing heat detection systems is also presented. C-I-I.1 This a p p e n d i x utilizes the results of fire research funded by the Fire Detection Institute to provide test data and analysis to the NFPA Technical Committee on Detection Devices. (See reference 2.) C-1-1.2 This a p p e n d i x is based on full-scale fire tests in which all fires were geometrically growing flaming fires. C-1-1.3 T h e guidance applicable to smoke detectors is limited to a theoretical analysis based on the flaming fire test data and is not intended to address the detection of smoldering fires. C-1-2 Purpose. T h e purpose of this a p p e n d i x is to assist fire alarm system design engineers concerned with the spacing of heat or smoke detectors. C-1-2.1 This a p p e n d i x is intended to provide a method for modifying the listed spacing of both rate-of-rise and fixed t e m p e r a t u r e heat d e t e c t o r s r e q u i r e d to achieve detector response to a geometrically growing flaming fire, at a specific fire size, taking into account the height of the ceiling on which the detectors are mounted. This proced u r e also permits modification of listed spacing of fixed t e m p e r a t u r e heat detectors to account for variation o f ambient t e m p e r a t u r e (Ta) from standard test conditions. C-1-2.1.1 This a p p e n d i x may be used to estimate the fire size that can be detected by an existing array of listed heat detectors installed at a given spacing for a given ceiling height in known ambient conditions. C-1-2.2 T h e a p p e n d i x is also i n t e n d e d to explain the effect of rate of fire growth and fire size of a flaming fire, as well as the effect of ceiling height on the spacing of smoke detectors.

APPENDIX C C-1-2.3 This design m e t h o d o l o g y utilizes theories of fire development, fire p l u m e dynamics, a n d detector performance, which are the major factors i n f l u e n c i n g detector response. However, it does not consider several lesser phen o m e n a that, in general, are unlikely to have significant influence. A discussion of ceiling drag, heat loss to the ceiling, radiation to the detector from a fire, reradiation of heat from a detector to its s u r r o u n d i n g s , a n d the heat of fusion of eutectic materials in fusible e l e m e n t s of heat detectors a n d their possible l i m i t a t i o n s o n the d e s i g n m e t h o d are p r o v i d e d in reference 9.

C-1-3 Relationship to Listed Spacings. Listed spacings for h e a t d e t e c t o r s a r e b a s e d o n relatively large fires (approximately 1200 Btu/sec) b u r n i n g at a c o n s t a n t rate. [The listed spacing is based on the distance from a fire at which an o r d i n a r y d e g r e e heat detector actuates prior to operation o f a 160°F (71.1°C) sprinkler installed at a 10 ft (3 m) spacing. See Figure A-3-5.1(a).] Design spacing for this type of fire can be d e t e r m i n e d using the material of C h a p t e r 3. W h e n smaller fires a n d v a r y i n g growth rates m u s t be considered, the d e s i g n e r may use the material p r e s e n t e d by this a p p e n d i x .

T h e fire growth time, t_, is arbitrarily defined as s the time, after established b u r n i n g , when the fire would reach a b u r n i n g rate of 1000 Btu/sec.

AUTOMATICFIRE DETECTORS

C-2-2.3.3 T h e design fires used in this g u i d e ~row according to the following equation: Q = [1000/(tg) "] t 2, where Q is the heat release in Btu/sec; tg is the fire growth time (149 sec = fast, 150-399 sec = medium, 400 sec = slow); and t is the time, in seconds, after open flaming OCCURS.

C-2-2.4 Selection of Fire Size. The selection of threshold fire size, O~, should be based on an u n d e r s t a n d i n g of the characteristics of a specified space and firesafety objectives for that space. For example, in a particular installation it may be desirable to detect a typical wastebasket fire. Table C-2-2.2. l(b) includes a fire involving a comparable array of combustibles, specifically milk cartons in a wastebasket. Such a fire is indicated to produce a peak b u r n i n g rate of 100 Btu/sec. C-2-3 C e i l i n g H e i g h t .

C-2-3,1 The Fire Detection Institute data are based on the height of the ceiling above the fire. In this guide, it is recommended that the designer use the actual distance from floor to ceiling, since the ceiling height will thereby be more conservative, and actual detector response will improve when the potential fuel in a room is above floor level. C-2-3.2 W h e r e the d e s i g n e r desires to c o n s i d e r the height of the potential fuel in the room, the distance between the fuel and the ceiling should be used as the ceiling height. This should be considered only when the minimum height of the potential fuel is always constant, and where the concept is acceptable to the authority having jurisdiction. C-2-3.3 The procedures presented in this appendix are based on an analysis of test data for ceiling heights up to 30 ft (9.1 m). No data was analyzed for ceilings greater than 30 ft (9.1 m). Therefore, in such installations engineering j u d g m e n t and manufacturers' recommendations should be used. C-3 H e a t Detectors. C-3-1 G e n e r a l .

C-3-1.1 This chapter discusses procedures for determination of installed spacing of listed heat detectors used to detect flaming fires. C-3-1.2 T h e d e t e r m i n a t i o n of the installed spacing of heat detectors using these procedures adjusts the listed spacing to reflect the effects of ceiling height, threshold fire size, rate of fire development, and, for fixed temperature detectors, the ambient temperature and the temperature rating of the detector.

possible. To reduce u n w a n t e d alarms, the difference between operating temperature and ambient temperature should be not less than 25°F (14°C). C-3-1.5 Listed rate-of-rise heat detectors are designed to activate at a nominal rate of temperature rise of 15°F per minute (8.3°C/rain). C-3-1.6 The listed spacing of a detector is an indicator of the detector's sensitivity. Given the same temperature rating, a detector listed for a 50 ft (15.2 m) spacing is more sensitive than one listed for a 20 ft (6.1 m) spacing. C-3-1.7 When using combination detectors incorporating both fixed t e m p e r a t u r e and rate-of-rise heat detection principles to detect a geometrically growing fire, the data herein for rate-of-rise detectors should be used in selecting an installed spacing because the rate-of-rise principle controls the response. C-3-1.8 Rate compensated detectors are not specifically covered by this appendix. However, a conservative approach .to predicting their performance is to use the fixed temperature guidance contained herein.

C-3-2.1 Tables C-3-2.1.1 and C-3-2.1.2(a) through (y) are to be used to determine the installed spacing of fixed temperature heat detectors. The analytical basis for the tables is presented in this appendix. This section describes how the tables are to be used. C-3-2.1.1 Except for ceiling height, the nearest value shown in the tables will provide sufficient accuracy for these calculations. Interpolation is allowable but not necessary except for ceiling height. Table C-3-2.1.1

NOTE 1: Thesetime constantsare based un an analysisof the Underwriters Laboratories Inc. and Factory Mutual listing test procedures. Phmge test~results performed on the detector to be used willgive a more accurate time constant. See Section C-6 of this appendix fi~r a further discussionof detector time constants. NOTE 2: These time constantscan be converted to response time index (RTI) values by multiplyingby ~//5 ft/sec.(See. C-6-3.) *At a reference velocityof 5 ft/sec.

C-3.1.3 Other factors that will affect detector response are treated in Chapter 3.

C-3-2.2 Given the detector's listed spacing and the detector's rated temperature (Ts), use Table C-3-2.1.1 to find the detector time constant (DET TC). The time constant is a measure of the detector's sensitivity. See Section C-5.

C-3-1.4 T h e difference between the rated temperature of a fixed temperature (T~) detector and the m a x i m u m ambient temperature (To) at the ceiling should be as small as

C-3-2.2.1 Response time index (RTI) can also be used to describe the sensitivity of a fixed temperature heat detector. See Section C-6.

Note: If the ceiling height is 16 It, the spacing is 8.8 ft. Using the'detector in the above example, at a ceiling height of 28 ft, no practical spacing would ensure detection of the tire at the threshold fire size of 500 Btu/sec. A more sensitive detector would need to be used. These results clearly illustrate the need to consider ceiling height in the design of a detection system. For SI Units:

I ft = 0.305 m.

AUTOMATICFIRE DETECTORS

C-3-3.4 Having determined the threshold fire size (C-2-2.2), the fire growth rate (C-2-2.3), the detector's listed spacing, and the ceiling height, use Table C-3-3.2 to determine the corrected spacing for 50 ft (15.2 m) listed detectors. Use Table C-3-3.3 to determine the spacing modifier. Find the required installed spacing by multiplying the corrected spacing by the spacing modifier.

C-3o3.4 Example.

Input:

Spacing:

Ceiling Height: Detector Type:

12 ft (3.7 m) Combination rate-ofrise, fixed temperature 30 ft (9.1 m) listed spacing Q , / = 500 Btu/sec Fire Growth Rate = medium From Table C-3-3.2, installed spacing = 18 ft (5.5 m) From Table C-3-3.3, spacing modifier = 0.86 Installed spacing = 18 x 0.86 = 15.5 ft (4.7 m).

C-3-4.1.4 Once a threshold size and expected fire growth rate have been selected, an installed detector spacing can be obtained from Figures C-3-4.1 (a)-(i) for a certain detector's listed spacing, ambient, temperature, and ceiling height. As in Section C-3-2.5, Example 1, to determine the installed spacing of 135°F (57.2°C) fixed temperature heat .detectors with a listed spacing of 30 It. (9.1 m), to detect a slowly developing fire at a threshold fire size of 500 Btu/sec (527 kW) in a room 10 ft (3 m) high with an ambient temperature of 70°F (21.1°C), the following procedure is used:

Example 1.

h,put:

10 fi (3 m) Fixed temperature 135°F (57.2°C) listed spacing, 30ft(9.1 m) O~: 500 Btu/sec (527 kW) Fire growth rate: slow Ambient temperature: 70°F (21. I°C); AT = 65°F (36.1°C)

Spacing:

From Figure C-3-4.1(a), use an installed spacing of 17 ft (5.2 m).

Ceiling Height: Detector Type:

C-3-4 Design Curves. C-3-4.1 The design curves [Figures C-3-4.1 (a)-(i)] may also be used to determine the installed spacings of heat detectors. However they are not as comprehensive as the tables because the tables include additional fire growth rates, fire sizes, and detector sensitivities.

Note that if the ceiling height is 15 ft (4.6 m), the same graph gives an installed spacing of 12 ft (3.5 m). A ceiling height of 20 ft (6.1 m) would require a spacing of 8 ft (2.4 m). Tiffs change in spacing clearly illustrates the need to consider ceiling height in the design of a detection system.

Co3-4.1.1 Fixed Temperature Heat Detectors.

Figures C-3-4.1 (a), (b), (c), (d), (e), and (f) can be used directly to determine the installed spacing for fixed temperature heat detectors having listed spacings of 30 ft and 50 ft (9.1 m and 15.2 m), respectively, when the difference between the detectors' rated temperature (Ts) and the ambient temperature (To) is 65°F (18.3°C). When AT is not 65°F (18.3°C), tables previously discussed in Section C-3-3 should be used.

C-3-4.1.5 Example 2.

Input:

C-3-4.1.2 Rate-of-Rise Heat Detectors. Figures C-3-4.1(g), (h), and (i) can be used directly to determine the installed spacing for rate-of-rise heat detectors having a listed spacing of 50 ft (15.2 m). C-3-4.1.3 To use the curves, the same format must be followed as with tables. The designer must first determine how large a fire can be tolerated before detection can occur. This is the threshold fire size, Q4. Curves are presented, in most cases, for values of Qa = 1000, 750, 500, 250, 100 Btu/sec (1055, 791,527, 264, and 105 kW). Interpolation between values of Q,/on a given graph is allowable. Table C-2-2.2.1(a) also contains examples of various fuels and their fire growth rates under specified conditions.

1990 Edition

Ceiling Height: Detector Type:

10 ft (3 m) Combination rate-of-rise and fixed temperature; 50 ft (15.2 m) listed spacing Q,/: 500 Btu/sec (527 kW) Fire growth rate: ifast Ambient temperature: 70°F (21.1°C); AT = 65°F (36.1°C)

Spacing:

From Figure C-3-4.1(i), use an installed spacing of 20 ft (5.8 m).

A 30 ft (9.1 m) fixed temperature detector would require a 7.5 ft (2.5 m) spacing. If the fire growth rate was slow, as in Example 1, the rate-of-rise detector would require an installed spacing of 16 ft (4.88 m).

AUTOMATIC FIRE DETECTORS

C-4 Analysis of Existing Heat Detection Systems.

ANALYSIS TABLES INDEX INSTALLED SPACING FEET

I C-4-1 Tables C-4-1(a)-(nn) can be used to d e t e r m i n e the size fire (heat release rate) which existing fixed t e m p e r a t u r e heat detection systems will r e s p o n d to. .

T h e use of the analysis tables is similar to that described for new designs. T h e difference is that the spacing of the existing detectors m u s t be known. An estimate of the fire intensity coefficient alpha or the fire growth time, t,r m u s t also be m a d e for the fuel that is expected to b u r n .

Example. Input:

Ceiling Height: 8 ft Detector Type: Fixed t e m p e r a t u r e 30 ft. U.L. listed spacing 135°F rated t e m p e r a t u r e Installed Spacing: 15 ft Fire Growth Rate: slow t~, = 600 sec (X = 0.003 Btu/sec 3) M i n i m u m A m b i e n t T e m p e r a t u r e = 55°F

C-5 Smoke Detector Spacing For Flaming Fires. C-5-1 General. C-5-1.1 Ideally, the placement of smoke detectors should be based on a knowledge of fire plume and ceiling j e t flows, smoke production rates, particulate changes due to aging, and the unique o p e r a t i n g characteristics of the detector being used. Knowledge of plume and j e t flows enabled the heat detector spacing information presented in Section C-3 to be developed. Unfortunately, that knowledge does not apply to smoke originating from smoldering fires. U n d e r s t a n d i n g of smoke production and aging lags considerably behind that of heat production. The operating characterisitics of smoke detectors in specific fire environments are not often measured or made generally available for o t h e r than a very few combustible materials. Hence, the existing data base precludes the development of complete e n g i n e e r i n g design information for smoke detector location and spacing. C-5-1.2 In flaming fire, s m o k e d e t e c t o r r e s p o n s e is affected by ceiling height, size, and rate of growth of the fire in much the same way as heat detector response. T h e thermal energy of the flaming fire transports smoke particles to the smoke sensor just as it does heat to a heat sensor. While the relationship between the a m o u n t of smoke and the a m o u n t of heat p r o d u c e d by a fire is highly depend e n t upon the t"uel and the way it is burning, research has shown that the relationship between t e m p e r a t u r e and optical density of smoke remains essentially constant within the fire p l u m e and on the ceiling in the proximity of the phnne. C-5-1.3 In smoldering fires, thermal energy also provides a force for transporting smoke particles to the smoke sensor. However, because the rate of energy release is usually small and the rate of growth of the fire is slow, other factors such as airflow may have a stronger influence on the transport of smoke particles to the smoke sensor. Additionally, for smoldering fires, the relationship between temperature and the optical density of smoke is not constant and therefore not useful. C-5-1.4 S m o k e detectors, r e g a r d l e s s of w h e t h e r they detect by sensing scattered light, loss of light transmission (light extinction), or reduction of ion current, are particle detectors. Particle concentration, size, color, and size distribution affect each sensing technology differently. It is generally a c c e p t e d that the c o n c e n t r a t i o n o f s u b - m i c r o n diameter particles p r o d u c e d by a flaming fire is greater than that p r o d u c e d by a smoldering fire. Conversely, the concentration of larger particles is greater from a smoldering fire. It is also known that the smaller particles agglomerate and form larger ones as they age and are carried away from the fire source. More research is required to provide sufficient data to first predict particle concentration and behavior and secondly to predict the response of a particular detector.

C-5-2 Smoke Detector Spacing for Flaming Fires. C-5-2.1 Unlike heat detectors, listed smoke detectors are not given a listed spacing. It has become general practice to install smoke detectors on 30 ft (9.1 m) centers on

72E- 127

smooth ceilings with reductions made empirically to that spacing for beamed or joisted ceilings and fi)r areas having high rates of air movement. Adjustments of spacing fi)r ceiling height are also necessary as discussed herein. (1-5-2.1.1 Figures C-5-2.l.l(a), (b), and (c) are based on the assumption that smoke t r a n s p o r t to the detector is entirely from fire plume dynamics. It assumes that the ratio of the gas t e m p e r a t u r e rise to the optical density of the smoke is a constant and that the detector will actuate at a constant value of optical density. T h e data presented in Figures C-5-2.1.1 (a), (b), and (c) clearly indicate that spacings considerably greater than 30 ft (9.1 m) are acceptable for detecting geometrically growing flaming fires when Q,t is 1000 Btu/sec or more. C-5-2.1.2 In the early stages of development of a growing fire, when the heat release rate is approximately 250 Btu/sec or less, the environmental effects in spaces having high ceilings may dominate the transportation of smoke. Examples of such environmental effects are heating, cooling, humidity, and ventilation. G r e a t e r thermal energy release fi-om the fire may be required to overcome such environmental effects. Until the growing fire reaches a sufficiently high level of heat release, closer spacing of smoke detectors on the ceiling will not significantly improve the response of the detectors to the fire. Therefore, when considering ceiling height alone, smoke detectors should not be placed closer than 30 ft (9.1 m) spacing except in unt, sual instances where an engineering analysis indicates additional benefit will result. Other construction characteristics must also be considered; see Chapters 4 and 9. C-5-2.2 T h e method used to determine the spacing of smoke detectors is similar to that used for heat detectors and is based on fire size, fire growth rate, and ceiling height. C-5-2.2.1 In o r d e r to use Figures C-5-2.1.1(a), (b), or (c) to d e t e r m i n e the installed spacing of a smoke detector, the designer must first select, Qa, the threshold flaming fire size at which detection is desired• C-5-2.2.2 In addition to threshold flaming fire size, 0.,/, the designer must consider the expected fire growth rate. Figures C-5-2.1. l(a), (b), and (c) are used for fast, medium, and slowly growing flaming fires, respectively. See Table C-2-2.2.1(a) for heat release rates and fire growth rates. Co5-2.2.3 As an example, to determine the installed spacing of a smoke detector on a 30-ft (9. l-m) ceiling required to detect a 750 Btu/sec fire that is growing at a medium rate, use Figure C-5-2.1.1 (b).

Example 3.

Input:

Ceiling Height: 30 ft (9.1 m) O~t = 750 Btu/sec (791 kW) Fire growth rate: medium

Spacing:

From Figure C-5-2.1.1(b), using the 750 Btu/sec (791 kW) curve, installed spacing is 41 ft (12.8 In).

As another example, consider a 20-ft (6. l-m) ceiling with a threshold fire size of 250 Btu/sec growing at a meditnn rate.

From Figure C-5-2.1.1(b), using the 250 Btu/ sec (264 kW) curve, installed spacing for the smoke detector is 30 ft (9.1 m) since the intersect of a vertical line at 20 ft (6.1 m) and the O~t = 250 curve falls within the shaded area below 30 ft (9.1 m) spacing. See C-5-2.1.2.

Note: Both a slow and fast rate of growth fire would resuh in the same 30 [i (9. I m) spacing using Figures C-5-2.1. l(c) and C-5-2.1.1(a).

C-5-2.2.4 Smoke detector spacings of less than 30 ft (9.1 m) nmy be used for detection of flaming fires where no other detector type is suitable and where environmental conditions allow the use of a smoke detector. C-6 Theoretical Considerations. c-6-1 I n t r o d u c t i o n . The design methods of this Appendix are the joint result of extensive experimental work and of mathematical modeling of the heat and mass transfer • t 1,2,8,t.) processes m~olved. This section outlines models and data correlations used to generate the design data presented in this appendix. Only the general principles are described. More detailed information may be obtained from the references.

C-6-2 Temperature and Velocity Correlations. In order to predict the operation of any detector, it is necessary to characterize the local e n v i r o n m e n t created by the fire at the detector location. For a heat detector the important variables are temperature and velocity of the gases at the detector. T h r o u g h a program of full-scale tests and using mathematical modeling techniques, general expressions for temperature and velocity at a detector location have been developed. ''~'~':~The expressions are valid for fires that grow according to Q = xff where Q is the theoretical fire heat release rate, X is the fire intensity coefficient characteristic of a particular fuel and configuration, and t is time. The calculations used to produce the spacing curves assume that the ratio of the actual convective heat release to the theoretical heat release for all fuels is equal to that ratio for wood crib fires.

C-6-3 Heat Detector Model. The heating of a heat detector is given by the equation, s dTo dt

_ (l) ( T ~ - T d ) (Y)

, where: T a = temperature rating of the detector .~..g= gas temperature at the detector = detector time constant (DET TC)

72E-131

C

The time constant is a measure of the detector's sensitivity and is given by: MC yhA where: M C h A

= = = =

the detector element mass detector element specific heat convection heat transfer coefficient surface area of detector element

h varies approximately as the square root of the gas velocity, U. It is customary to speak of the time constant Y at a reference velocity of U o = 5fps. Y = Y,, (Uo / U) "~ Y can be measured most easily by a "phmge test. '':* It can also be related to the listed spacing of a detector through a calculation;z Table C-3-2.1.1 results fi'om these calculations. This model uses the temperature and velocity of the gases at the detector to predict the temperature rise of the detector element. Detector operation occurs when the preset conditions are reached. The detector's sensitivity can also be expressed in units that are i n d e p e n d e n t of the air velocity used in the test to d e t e r m i n e the time c o n s t a n t . T h i s is k n o w n as the Response Time Index, RTI. m

RI1 = 'r V U The RTl value can therefore be obtained by multiplying T,, values by X/U~:,;for example, when 67U'.~ 5 ft/sec, a % of 30 sec corresponds to an RTI of sec '/'' ft ~/'' or 35.9 sec I/~ m '/''A detector having a RTI of 67.1 sec'/'' ft '/~ would have a "r of 23.7 sec, if measured in an air velocity of 8 ft/seo

C-6-4 Ambient Temperature Considerations. (Reference also 3-2.1.2.) T h e m a x i m u m a m b i e n t t e m p e r a t u r e expected to occur at the ceiling dictates the choice of temp e r a t u r e rating for a fixed t e m p e r a t u r e heat detector application. But the m i n i m u m ambient temperature likely at the ceiling constitutes the worst-case condition for response by that detector to a fire. The mass, specific heat, heat transfer coefficient, and surface area of a detector's sensing element characterize that detector's time constant. The response time by a given detector to a given fire depends only on the detector's time constant and the difference between the detector's temperature rating and the ambient temperature at the detector when the fire starts. When ambient temperature at the ceiling decreases, more heat from a fire will be needed to bring the air s u r r o u n d i n g the detector's sensing element up to its rated (operating) temperature; this translates into slower response and, in the case of a growing fire, a larger fire size at the time of detection. In a room or work area that has central heating, the m i n i m u m ambient temperature would usually be 70°F (21.1°C). Certain warehouse occupancies may only be heated enough to prevent water pipe freeze-up; in that case the m i n i m u m ambient should be considered 35°F (2°C) even though d u r i n g many

months of the year the actual ambient is much higher. An unheated building in northern states and Canada should be p r e s u m e d to have a minimum ambient o f - 4 0 ° F (-40°C) or lower. C-6-5 H e a t and S m o k e A n a l o g y -- S m o k e D e t e c t o r Model. For smoke cletectors, the t e m p e r a t u r e of the gases at the detector is not directly rclcvant to detection, but the mass concentration and size distribution of particulates are relevant. For many types of smoke, the mass concentration of particles is directly proportional to the optical density of tlae smoke, D,,. A general correlation for flaming fires has been shown to exist between the temperature rise of the fire gases at a given location and the optical density. If the optical density at which a detector responds, Do, was known and was i n d e p e n d e n t of particle size distribution, tbc response of the detector could be a p p r o x i m a t e d as a function of heat release rate of the burning fuel, rate of fire growth, and ceiling height, assuming that the above correlation held. However, the more popular ionization and light scattering detecto,'s cxhibit widely different D o whcn particle size distribution is changed; hence, whcn DOfor these detectors is meast, rcd in o r d e r to predict response, the test aerosol used must be vet'), carefully controlled so that particle size distribution is constant.
