Panel Power
Panel does not power up and does not display or respond.
1. Check that panel transformer is plugged into an unswitched outlet.
2. Check the AC circuit breaker to be sure the circuit is live.
3. Check that the backup battery is installed correctly and the AC power transformer is plugged in.
4. Check for proper panel and transformer wiring.
5. Measure the incoming AC voltage at panel terminals 1 and 2. It should read about 8 VAC.
No incoming AC voltage at panel terminals 1 and 2.
1. Unplug the AC power transformer and disconnect the wires from the transformer and the panel.
2. Check transformer to panel wire for short or open circuits.
3. Plug in the transformer and check for 8.0 VAC at the transformer unconnected terminals. If zero (0)
volts, replace the transformer. If transformer is good, call Tech Support.
Panel display indicates Low CPU Battery.
Note
If the AC power was out for an extended period of time, the battery may not be fully charged yet.
1. Perform a battery test by entering and exiting sensor test.
2. Check that the backup battery is installed correctly and the AC power transformer is plugged in.
3. Measure the incoming AC voltage at the panel terminals 1 and 2. It should read about 8 VAC.
4. Remove the backup battery power by disconnecting the battery and replace the battery.
Note
If AC power is present, the battery voltage is only monitored during a backup battery test. The panel
automatically runs a backup battery test under the following conditions: (1) during user sensor test,
(2) once every 4 hours, (3) when the back cover is closed. In order for the panel to update the battery
status, a backup battery test must be run.
Note
With the AC power transformer plugged in, the panel automatically charges the battery. While the
battery is charging for the first time it is normal for the system to indicate Low CPU Battery. Charging
the battery can take a number of hours depending on the battery’s initial charge. Once the battery
reaches 4.8 VDC (full charge as measured while in battery test), the condition clears. If the trouble
condition persists after 24 hours, replace the backup battery. A Low Battery report to the central sta-
tion will not be made for the first 24 hours after power up.
After pressing STATUS the panel flashes AC Fail, (panel continues to operate from backup battery).
1. Check the AC circuit breaker to be sure the circuit is live.
2. Check for proper panel and transformer wiring.
3. Check that the transformer is supplying AC to the panel.
4. Check that the transformer is plugged into a nonswitched outlet and secured with the provided screw.
WARNING
!
Be careful when securing the transformer to an outlet with a metal cover. Hold the cover tightly in
place. You could receive a serious shock if the metal outlet cover drops down onto the prongs of
the plug while you are securing the transformer and cover to the outlet box.
