Fire Notification Systems
The primary function of the notification appliance is to alert persons at risk. Several methods are used and documented in industry specifications. Alerting methods generally include sound, light and textual. These methods are intended to trigger a response other than evacuation, such as clean agent warning annunciation, or shelter in place tones.
Fire alarm voice evacuation system uses speakers and amplifiers to notify occupants with an alarm tone followed by a voice instead of the traditional horn or bell. Also provides ability for live voice announcements by the fire department or emergency personnel through a local paging microphone. These voice evacuation systems are most commonly installed in two types of building occupancies:
- Place of Assembly: Where more than 50 people congregate, but may be unfamiliar with exit locations, or fire emergency signals, voice systems can instruct people to remain calm, and to evacuate the building.
- High Rise: When it is impractical to evacuate a building in its entirety, zoned evacuation of the occupants is used to conduct an instructed evacuation of floors or areas within the building.
