How Fire detection and alarm system Works?


#1

A fire detection and alarm system may be activated by automatic detection devices or by manual operation and should fulfil its functions without errors or omissions, including

  • detecting quickly enough to fulfil its intended function,

  • reliably transmitting the detection signal to the control and indicating equipment and, if applicable, the fire alarm receiving station,

  • translating the detection signal into a clear alarm signal that will attract the attention of occupants in an immediate and unmistakable way,

  • remaining insensitive to phenomena other than those which its function is to detect, and

  • signalling immediately and clearly any supervised fault that might jeopardize the correct performance of the fire detection and alarm system.

A fire detection and alarm system should not

  • be adversely affected by any other systems whether associated with it, or not

  • be rendered partially or totally inoperative by the fire or the phenomenon which it is designed to detect before the fire or phenomenon has been detected.


#2

The Fire Alarm and Detection Systems can be set off automatically by smoke detectors, heat detectors or manually.
