When people call my home they hear “System System” or a fax like tone?

The alarm panels do have the ability to answer an incoming call. The person calling will hear a “fax” like tone or the words “System System”. This feature is activated by calling the home allowing the phone to ring one time, then calling back to the same number. This feature is used for our back office systems to access the programming in your security system when changes are needed or for your system to be controlled using your touch tone phone (if available).
