Table T1: Panel Power Troubleshooting
Problem
Action/Solution
Panel does not power up. Touchpads don’t
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 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.
1.
Check that the backup battery is installed correctly and the AC
power transformer is plugged in.
2.
Measure the incoming AC voltage at the panel terminals 1 and 2. It
should read about 16.5 VAC.
3.
Remove the backup battery power by disconnecting the red (posi-
tive) battery wire. Check for 11.75 to 13.5 VDC battery charging
voltage between panel terminal 3 (GND) and the disconnected red
battery wire. If the charging voltage is not within range, call Techni-
cal Services.
4.
Check for 11.75 to 13.5 VDC battery voltage between the backup
battery spade lugs. If the battery voltage is not within this range,
replace the battery.
Ìi
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 follow-
ing 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).
Ìi
With the AC power transformer plugged in, the panel automati-
cally charges the battery. While the battery is charging for the
first time it is normal for the system to indicate
System battery
failure
. 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.
After you press STATUS, the touchpads flash
AC or display AC Power Failure/AC Failure.
(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 plugged into a nonswitched outlet and
secured with the provided screw.
4.
Check that the transformer is supplying AC to the panel. (Trans-
former internal fuse may be blown.)
7,
!
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.
