Automatic Fire Detection and Alarm System
Automatic fire detection and alarm system is primarily a life safety system meant for detecting the fire at the early stages and alarm the occupants. The fire detection system is also used for automatic activation of fire extinguishing systems such as spray systems, water mist systems and gas suppression systems. The control relay modules in the advanced addressable detection systems enable the integration and operation of ancillary services such as electrical systems, fire dampers, access control systems, video surveillance, emergency lighting systems, emergency communication systems etc. to activate/deactivate in case of emergencies.
Description of Automatic Fire Detection and Alarm System as follows:
Analogue-addressable fire alarm systems give details on individual detectors, whereas conventional systems only give information about specific circuits or zones. Addressable or “intelligent” fire alarm systems are designed for large commercial premises and more complex networked systems, since they are much more expensive and more complicated than conventional two- or four-wire systems, having increased flexibility, intelligence, speed of identification, and scope of control.
Types of Detectors
The efficiency of a fire detection and alarm system depends on various factors such as selection of suitable type of detector, spacing between detectors, mounting locations, rate of air flow, room temperature, humidity level, presence of dust particles, type of ceiling etc.
