FAS (Fire Alarm System)
Early warning life safety systems that protect people and property from fire hazards
What is a Fire Alarm System?
A Fire Alarm System (FAS) is a network of devices that detect fire, smoke, or heat and alert occupants to evacuate. It includes detectors, manual call points, notification devices (sounders/strobes), and a control panel. FAS is mandatory for all commercial buildings as per NBC (National Building Code) and NFPA standards.
Addressable
Exact device location
Conventional
Zone-based detection
Smoke Detection
Early fire warning
Heat Detection
Kitchen/Garage safe
Addressable and Conventional Fire Detection
Addressable: Each device has unique ID, panel shows exact location. Conventional: Zones, panel shows zone only.
Addressable: Each device has unique ID, panel shows exact location. Conventional: Zones, panel shows zone only.
Addressable: Large buildings (hotels, hospitals, malls). Conventional: Small offices, shops, apartments.
Devices on loop (addressable) or zone wiring (conventional). Panel polls devices for status.
Mandatory for all commercial buildings as per fire safety codes (NBC, NFPA).
Why used? Addressable: Faster pinpointing of fire location. Conventional: Lower cost for small sites.
Addressable: Room 204
Conventional: Zone B
Smoke and Heat Detectors
Smoke detector: Senses smoke particles (ionization or photoelectric). Heat detector: Triggers at fixed temperature or rapid temperature rise.
Smoke detector: Senses smoke particles (ionization or photoelectric). Heat detector: Triggers at fixed temperature or rapid temperature rise.
Smoke: Bedrooms, corridors, offices. Heat: Kitchens, garages, boiler rooms (where smoke causes false alarms).
Mounted on ceiling. Smoke detector uses LED/light scatter. Heat detector uses thermistor.
24/7 monitoring.
Why used? Early warning saves lives. Heat detectors work where smoke detectors can't (dusty, smoky environments).
Evacuation Plan & Emergency Response
Documented strategy showing escape routes, assembly points, and responsibilities during a fire.
Documented strategy showing escape routes, assembly points, and responsibilities during a fire.
Every building: offices, hotels, schools, hospitals.
Post floor plans showing exits. Conduct regular drills. Integrate with FAS for voice evacuation.
During fire alarm activation. Also during planned drills.
Why used? Legal requirement. Prevents panic. Ensures everyone knows where to go. Reduces injury/death.
Break Glass
Push Button
Manual Call Point (MCP)
Red break-glass or push-button device that allows a person to manually trigger the fire alarm.
Red break-glass or push-button device that allows a person to manually trigger the fire alarm.
Near exits, stairwells, corridors – every 30m as per code.
User breaks glass or presses button. Signal sent to fire panel. Panel activates sounders/strobes.
When someone sees fire before automatic detectors activate.
Why used? Provides human override. Catches fires that detectors might miss initially. Legal requirement.
