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.
|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 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
|Wired as separate circuit zone wise
|Can be wired in loops
|Basically not in-built
|System events are recorded in event log to take reports as per the requirement.
|Advanced programming options for programming the systems as per the user needs
|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.
