    Has anyone had someone recommend using fire alarm wire to connect the
    telco interface to the RJ31X? Seems like a reasonable suggestion
    since that line has to survive at least as long as the line between
    the panel and the smokes, but I am not aware of this being a code
    requirement. Comments welcome.

    It depends on the system. For commerical or institutional it is quite often
    speced to be in conduit if the fire panel is not in the phone room. I run
    plenum wire myself for it.

    I would hope that during the "onset of the fire" the alarm system's
    communicating the problem to the CS and the trucks are rolling... By the time
    it get's hot enough to burn either plenum rated cable or standard FT-4, the
    chances of any signal getting through is slim to nil. It's why you run it in
    conduit, or use mineral cable.

    Twisted pair telephone cable would be less prone to pick up interference.
    For short runs fire alarm wire would not make a difference but if you were
    installing long runs in noisy industrial environments or you were installing
    in a area know to have problems with RF coupling into phone lines adhering
    to clean wiring practices would be prudent.
