"Trouble" light will come ON and the buzzer will sound 2 short beeps every 10 seconds. To silence the buzzer,
press the [#] key. The buzzer will stop but the "Trouble" light will remain ON until the trouble condition is cleared.
Refer to Programming Sections [39] and [40] for information on the trouble conditions that can be transmitted to

1 Low Battery. If the battery voltage is low, the battery is disconnected or the battery fuse is blown, a trouble
will be displayed and can be reported. Only one low battery trouble and restoral transmission will occur per
armed period. The low battery trouble display is "latching", and can only be cleared by correcting the
problem with the battery.
2 AC Failure. On loss of AC power, the "Trouble" light will come ON immediately, but the keypad buzzer will
not sound. The keypad buzzer will sound if AC power remains off and the battery reaches a low voltage.
The delay before transmitting AC Fail can be programmed from 1 to 99 minutes. See Programming Section
[42].
