Is Your Fire Alarm System Really Communicating?

by Adam Jacobs 11/18/2021

We recently discovered, through numerous tests, that most (if not all) of the newer modem (telephony/VOIP) phone lines are NOT redundant.  So even if you have two phone numbers, if one line is down they're BOTH down.  This is how the modem works.  It's assigning two different phone numbers, but they are communicating over the same "line".  So, if you have phone service that uses a modem and you are using them for your fire alarm be sure you ask the installing technician these two questions:

Is my modem programmed to fake analog phone lines? - this is the only way that the the fire alarm panel will recognize these lines

If one "line" isn't working, do I still have a backup "line" so that my fire alarm panel can communicate an alarm?

Telephony is fine, and it can save you money, but be sure you're not sacrificing your safety. 

CenturyLink is the only telephone service provider in our area that provides true analog phone lines that ALWAYS work with fire alarm communicators.  This isn't a plug for CentruyLink, is simply a fact that we've revealed through years of experience.

 

Research your telephone service.  You DON'T want your fire protection to be "phony".
