What NFPA says, when I have installed FM 200 system(mechanical & electrical -means detection system) in computer room, is that required to install again a Fire alarm system in the same computer room?
Usually FM-200 are stand-alone systems. If required to be interfaced to the building fire alarm system, you may use interface monitor relays/ modules to do so. Meaning to say to monitor the FM-200 Status " i.e. Gas release, Smoke/ Heat Detector's status, Manual release". Installing other detectors related to building fire alarm system is meaningless in this case.
It is a mis undrstanding that Building fire alarm system on confirm fire can not trip FM200 system and there is a need for seperate Fire Decteion system for FM 200 protected room. I also find it in many protection but feel that it is not correct and waste of resources.
