3 An alarm system may beactivatedby automaticdetection devices or by manual operationofmanual call standard covering the requirementsofheat sensitive fire 'detectorswas first published in 1962 and revised in1976, 1988 and 1999. The present revision includes modifications with regard to terminology, inclusionofprobetypehightemperaturebi-me talheatdetector,opticalsmokedetector,spa rk/emberdetector,UVflamedetector, IR flame detector etc, and figures for arrangement for smoke detectors andaddressablefire detectionand alarm below are for guidance to design and constructionoffire detection and alarmsystems. A firedetectionand alarm system should:a) detect quickly enough to fulfil its intended functions;b) reliably transmit the detection signal;c) translate this signal into a clear alarm indication that will attract the attentionofthe user in an immediateand unmistakable way and indicate the locationoffire and initiate operationofancillary service, such asfire extinguishing system, etc;d) remain insensitive to phenomena other than those where its function is to detect.

Compatibility should be considered when designing a system.
