Troubleshooting Service Conditions
Your system notifies you if a keypad, sensor, or other system com-
ponent, needs service by lighting the Service LED and by beep-
ing twice every 30 seconds for one minute.
To get more information about the service message, press and
hold the
[service] key for two seconds until you hear two
beeps. One or more of the LEDs of Zones 5, 6, 7, and 8 light. As
the table below shows, different messages are conveyed depend-
ing on which LEDs are lit. (In the table, lit LEDs are shown in
black.) Follow the recommended course of action listed in the
table.
To stop the service message warning tone, enter your user code
between the two beeps.
You may have more than one service message. To view the next
message, press the
key again. If there are no new mes-
sages, your keypad exits the Service Message display.
