“3” (with three flashing lights) or “Comm Fail” display on the keypad means failure to communicate.
Your alarm system is having trouble contacting our central station.
Some of the common causes may be any of the following:
- Disconnected or cut telephone line
- Failed alarm digital communicator
- Interrupted telephone company provider service
The first thing you need to do is test your alarm with our central station.
Once a successful test is completed the “3” or “Comm Fail” should disappear.
If the display remains, call our service department at (305) 253-5162, and a service call may be required to solve the problem.
