Q. My keypad reads “Com Fail.” What does that mean?
A. “Com Fail” refers to a “communication failure.” This happens when your security system loses telephone communication due to a power failure. Communication failures can be a result of several conditions including but not necessarily limited to: telephone service interruption, cable outages, power outages, changes to the wiring in your home or business or even a severed telephone line. Generally, resetting your system clears the message. (To reset your system, simply arm it, then open a door or window, then disarm it by entering your code.)
