FIRE ALARM SYSTEM
The purpose of fire alarm and signaling systems shall be primarily to provide notification of alarm, supervisory, and trouble conditions, to alert the occupants, to evacuate, to summon aid and to control emergency control functions.
The Fire produces variety of reactions and characteristic signatures such as Smoke, Heat, Radiant Energy. However, different fires based on the fuel it is consuming, have different characteristic signatures such as some fires produce intense heat without smoke, some produce low heat with intense smoke and some burn without flame but produce smoldering smoke. The fire detectors are designed to identify and sense these various inputs and process the data to evaluate, compare and differentiate the environmental conditions or preset conditions to generate the output through control systems called “Fire Alarm”.
The Fire Detection and Alarm System essentially consists of Fire Detectors, communicating with Central Control Unit called Fire Alarm Control Panel through wiring or wireless signals to generate Alarm through sounders, bells and audio visual alarm devices. The entire components are powered by primary power supply and secondary power supply through Batteries.
