    buildings under control of one owner and protected by a single system
    where the system is monitored locally or remotely by the owner

  2. A supervised station system, which is much like a protected premise sys-
    tem except that the system is continuously monitored by a third-party
    security or central monitoring company; monitoring is addressed in
    the following ways:
     Local monitoring—When activated, a local alarm announces an
    alarm in the area that it covers
     Remote monitoring—When activated, a local alarm will be monitored
    remotely by building or campus personnel through a communica-
    tions network
     Supervised station—When activated, a local alarm will be monitored
    by an offsite company that provides recording, supervision and man-
    agement of the fire alarm system


Communications and IP


The fire alarm system must call out in case of alarm. The NFPA code requires
that a fire alarm’s digital alarm communicator/transmitters (DACTs) be

lines to call out to a supervising station or a primary telephone line with the
