FIXED FIRE PROTECTION SYSTEM INTRODUCTION Fire protection systems installed in buildings as cover t o equipment and the building itself from fire. Types of systems installed based based on the type of equipment placement, placement, risk of  fire and type of building own. FUNCTION OF FIXED FIRE PROTECTION SYSTEMS There are various types of fire protection systems. Among them are: a.

Tracking system and tell.

b.

Fire-fighting systems.

c.

Alarm system.

d.

A combination combination of the above systems.

DETECTION SYSTEMS AND NOTIFY To detect and notify not ify changing conditions conditions in the area or areas covered in the event of fire. System It is mounted in whole or in ventilation systems. The types of systems are (See Figure 1.2 and 3): a.

FIRE FIGHTING SYSTEM The system is divided into several categories they are: Shower Cleaning. Cleaning. Installed in a building whose height is not more than 200 the foot. A pump is needed to supply water for fire fighting either from the Fire Vehicle or Portable Pump. 4-inch diameter pipe There is also a 6-inch pipe is usually installed in the room stairs. The system is with such areas as: (1) Inlet Valve. Installed at the bottom of the system, the valve of water into the dry shower system. From the type of 'non-return valve 2 ½ inches in diameter. For pipe measures 6 inches with 4 valves in and the pipe is 4 inches a second valve. (2) Drain Valve. Installed at the bottom of the system, the valve to with draw water after the system is used. (3) Air Release Valve. Installed at the top of the system, is valve to remove air in the system while the system is is used. (4) Landing Valve. Installed Installed on each floor of the building, building, is valve for hose connection for fire fighting.

Wet shower  Installed in the building height exceeds 200 feet. Always have a pressure pipe, one or more pumps are installed fixed on the pipe involved.Standard building building measures 6 other  inci.Pump installed at a certain level, such as 'booster pump' to maintain the pressure in in the system. This system also has the same parts as Shower Cleaning. Hose Reel System For the initial stage fire fighting. Always have a pressure hose reels, diameter  3 / 4 inch or 1 inch and ready installed 100 feet long 'nozzle' at the end.

Foam System Installed at the 'hangar' to provide protection from fire and aircraft f uel oil. Managed by two X available personnel and equipment were hoses and FMB 1X stored in special boxes. 2 pumps installed to provide pressure pressure in the t he system.

Drencher System Installed to protect a building from fire hazard of an event in another building or  around it. Occupants of the building will open the valve system available available at the bottom or  side of buildings in the event of fire. Divided into three (3) types: (1)

Roof drencher (roof)

(2)

Wall drencher (wall)

(3)

Window Drencher (windows)

Alarm System This system will sound automatically when the system detect and inform the work or  manually sounded by the residents themselves when the visible f ire. The types of systems are (see Figure 8): a.

Penal Control It is the nerve center of the fire protection system in place in the conspicuous area of  the building or being supervised. There 'Mimic' that plan indication of the location of the control area or zone set. Lights on Control Panel shows: a. Red Light - Indicates that the fire has been detected in the zone alarms will sound. b.

 Yellow Lights - Showing no damage (fault) for the zone only.

c. Blue Lights - A system for f or the zone has been separated (isolate) to the maintenance maintenance / damage. Note. Note. When the light is yellow and blue does not ring alarm bells chime in only "buzzer" will sound only in the control panel CONCLUSION With this lesson let you know about Fire Protection System and able to operate the system more efficient.
