PHONE FAILURE
TROUBLE The system can’t communicate with the central monitoring station.
The system tries to report to the central station three times before
indicating Phone Failure Trouble, then makes five more reporting
attempts.
1. Make sure the panel is connected to the special phone jack
installed by your security dealer.
2. Disconnect the panel from the special phone jack and check
phones for dial tone. If you hear a dial tone, call your security
dealer for service. If you don’t hear dial from any phones,
telephone service in your area may be out.
Phone Failure Trouble takes precedence over other system problems,
so you must clear the Phone Failure message (by disarming the
panel) before you’re able to see other system messages.
