The ANSI 17.1 code requires emergency phone lines to be monitored, so if you lose power to your phone line, on‐site personnel need to know about it through both a visual and an audible signal.

We've developed a low‐cost, simple and effective method of complying. When a phone line goes down, our 901 series emergency phones send a signal through a relay to our Line Loss Indicator which then activates an audible warning along with a warning light within our Line Loss Display Panel. Monitor up to 8 phone lines, each with their own LED indicator.


  • Monitor up to 8 Phone Lines
  • Individual LED Indicator per Phone Line
  • Surface Mount Installation
  • Compatible with 901 Series Emergency Phones
  • Proudly Made in the U.S.A.
