Troubleshooting
This section describes what to do if you experience problems with system operation. If after per-
forming the troubleshooting procedures the panel still malfunctions, please call Technical Sup-
port at 1-800-777-2624.

Problem
Action/Solution
Panel Power
Panel does not power up. Touchpads don’t display or respond.
1.
Verify that the 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 16.5 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 16.5 VAC at the transformer unconnected terminals. If
zero (0) volts, replace the transformer.
Touchpad display indicates
System Low Battery
or voice sounds
“System low battery.”
1.
Check that the backup battery is installed correctly and the AC power transformer is plugged in.
2.
Measure the incoming AC voltage at panel terminals 1 and 2. It should read about 16.5 VAC.
3.
Check for 11.75 to 13.8 VDC battery voltage between the backup
battery spade lugs. If the battery voltage is
not
within this range, replace the battery.
Note
When the panel is running a backup battery test, the reading at the connected battery can range from
11.2 to 13.5 VDC. The panel automatically runs a backup battery test under the following conditions: (1)
on initial power-up, (2) during user sensor test, (3) once every minute when backup battery has failed,
(4) once every 24 hours at the programmed STIME (UL 98 Options off) or once every 4 hours (UL 98
Options on).
With the AC power transformer plugged in, the panel automatically charges the battery. While the bat-
tery is charging for the first time it is normal for the system to indicate System Low Battery. This can take
a number of hours depending on the initial battery charge. Once the battery reaches 12.5 VDC (full
charge as measured while in battery test), the condition clears. If the trouble condition persists after 24
hours, replace the backup battery.

. (Panel continues to oper-
ate 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 plugged into a nonswitched outlet and secured with the provided
screw.
4.
Check that the transformer is supplying AC to the panel. (Transformer internal fuse may be
blown.
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.
Access Codes
Customer cannot remember access code(s).
1.
Check your records to see if you have the customer’s access code(s) on file.
2.
Verify the access code(s) using the Downloader.
3.
Clear memory and reprogram the panel locally.
4.
Clearing the memory will erase onboard hardwire zone factory programming.
Installer cannot remember install code.
