Fire alarm systems
A Fire alarm system is a combination of a interlinked electric /electronic devices integrated to detect and alert on any incident of fire /smoke immediately on occurrence so that the measures for extinguishing the fire is taken at the earliest possible time to prevent loss of human life / material loss.
Fire alarm systems are mainly of 2 major types namely the conventional and the addressable systems. Some of the major differences are given below for better understanding of the 2 types of FAS.
|Parameter||Conventional Systems||Addressable systems|
|Detectors Identification||Detectors are identified zone wise||Each and every individual detectors /devices have a unique address defined and the faults can be traced easily|
|Alarm threshold||Alarm threshold levels setting for individual detectors not possible||Different alarm threshold levels can be set individually for each detectors depending on the area of use|
|Pre alarm warning||Pre alarm warning not available||Pre Alarm warning available which allows to know the problems in advance and helps to take necessary action|
|Wiring||Wired as separate circuit zone wise||Can be wired in loops|
|Event log||Basically not in-built||System events are recorded in event log to take reports as per the requirement.|
|Programming||Simple Programming||Advanced programming options for programming the systems as per the user needs|
|Configuration||Easy to configure zoned FAS||Complicated to setup|
Depending on the need and budget of the users the type of the FAS is selected and installed.
