WIRED (LANDLINE) REPORTING
The requirements for fire alarm signaling have been defined by the National Fire Protection Association (NFPA 72) National Fire Alarm and Signaling Code. Up through the 2010 revision to NFPA 72, building owners were required to provide two analog phone lines, at least one dedicated, over which the fire alarm communicator (DACT, or “dialer”) reported to a monitoring center at least once every 24 hours. The intended purpose of having two phone lines was to provide redundancy in case of a line failure. This required property owners to maintain two extra landlines, along with the associated monthly costs.
WIRELESS (CELLULAR) REPORTING
“Old-fashioned” landlines are tested with Central Station once a day and a single line failure is reported immediately over the remaining one, but in the event of total communicator or phone service failure, notification by default can take nearly 24 hours. The 2013 revision of NFPA 72, allows “sole-path” cellular technology (one cellular line instead of two analog lines). With the minimum 60-minute supervision, the cellular carrier knows within 1 hour of any communicator failure, and can report the condition to the monitoring center. With the OK of the local Authority Having Jurisdiction, an approved sole-path wireless communicator can set you free from those monthly landline charges and associated headaches!
