IWIRE is quite right about the speciality of Fire Alarm Systems. I say leave most of that stuff to the specialist. I would much rather inspect behind a Fire alarm specialest who is certified by N.I.C.E.T. (National Institute for Certification of Engineering Technology) than meet a person on the job who doesn't have a clue about the system. In all due respect to the pipe benders, they should leave some of this technology to the specialist who use NFPA 72.
Now answer my question: Do the smoke detectors under the raised floor of the computer room need to sound an alarm or just shut down the air flow?
