7 The fire alarm condition

5.1 Display of functional conditions

7.1 Reception and processing of fire signals

(see also annex 0)

5.1.1 The c.i.e. shall be capable of unambiguously indicating the following functional conditions, as described in clauses 6 to 10.

- Quiescent condition — Fire alarm condition. — Fault warning condition. ~ Disablement condition. — Test condition. 5.1.2 The c.i.e. shall be capable of being simultaneously in any combination of the following functional conditions. - Fire alarm condition. - Fault warning condition. - Disable ment condition. - Te st condition. 5.2 Display of indications All mandatory indications shall be cle arly identifiable, except whe re otherwise specified in this Europe an Standard. 5.3 Indications on alphanume ric displays Where an alphanumeric display is use d to display indications relating to differe nt functional conditions these may be displayed at the same time. Howe ver, for each functional condition the re shall be only one window, in which all of the fields relating to that functional condition are grouped. 5.4 Indication of the supply of power A visible indication shall be given by means of a. se parate light e mitting indicator while the c.i.e . is

supplied with power. 5.5 Audible indications The audible indication for the fire alarm C ondition may be the same as that for the fault warning condition. If they are differe nt, the fire alarm indication shall have priority. 5.6 Additional indications Where indications are used in addition to mandatory indications these shall not re sult in contradiction or confusion.

7.1.1 The c.i.e . shall enter the fire alarm condition when signals are received which afte r any necessary processing are interpre ted as a fire alarm. 7.1.2 The c.i.e . shall be capable of receiving, processing and indicating signals from all zones. A signal from one zone shall not falsify the processing, storing and/or indication of signals from othe r zones. 7.1.3 Unless 7.12 applie s, the time taken by scanning, interrogation, or other processing of signals from fire dete ctors, in addition to that require d to take the fire alarm de cision, shall not de lay the indication of the fire alarm condition, or of a new zone in alarm by more than 10 s. 7.1.4 The c.i.e . shall enter the fire alarm condition within 10 s of the activation of any manual call point. 7.1.5 The mandatory indications and/or outputs shall not be falsifie d by multiple fire signals re ceive d from the same or differe nt detection circuits, resulting from the simultane ous operation of two points and/or the operation of further points. 7.2 Indication of the fire alarm condition The fire alarm condition shall be indicate d without prior manual intervention. The indication is e stablishe d when all of the following are pre sent. a) A visible indication, by means of a se parate light emitting indicator (the ge neral fire alarm indicator). b) Avisible indication, as specified in 7.3, of the

zones in alarm, which may be omitted for c.i.e.s capable of receiving signals from only one z one. c) An audible indication, as specified in 7.4. 7.3 Indication of the zones in alarm (see also anne x D) 7.3.1 The zone s in alarm shall be visibly indicated by means of a se parate light emitting indicator for each zone and/or an alphanumeric display. 7.3.2 If the zonal indications are on an alphanume ric

display, which because of its limited capacity cannot simultaneously indicate all the zone s in alarm, at least the following shall apply. a) The first zone in alarm shall be displayed in a. fie ld at the top of the display.

b) The most recent zone in alarm shall be

6 The quiescent condition

pe rmanently displayed in another field.

Any kind of system information may be displayed during the quie scent condition. However, no indications shall be give n which could be confused with indications use d in the:

pe rmanently displayed. ’

- fire alann condition; - fault wanting condition;

- disabled condition; ~ te st condition.

c) The total number of zones in alarm shall be d) Zones in alarm not currently indicated shall be capable of being displayed at access level 1. A single manual action shall be re quired for each display of zonal information, which shall either be in the field

used for the first zone in alarm, or in another field. In the former case the display shall revert to the first zone in alarm between 15 s and 30 s following the last interrogation.
