Troubleshooting guide

Battery Trouble

In a normal condition, the panel tests the backup battery every 3 minutes by performing a

load-test on the battery. This test lasts for 5 seconds.

If the battery voltage falls below 11.9 VDC during this test, the panel generates a

[ BATTERY -TRBL ]. This signal is also sent to the central station

In the trouble condition, panel re-tests the battery every 2 minutes. When the battery’s DC

voltage rises to 12.6 VDC, the [ BATTERY -TRBL ] clears from the display and the restoral

is sent to the central station.

If the battery has been replaced and the trouble condition is still present, try getting into

and out of Programming. This re-starts the 3-minute load-test timer. This usually will

clear the [ BATTERY -TRBL ]. If not, try these steps:

1. Remove the AC wiring from terminals 1 & 2, so that only the battery powers the

panel.

2. Set your meter to DC voltage and place the leads on terminals 3 & 4. Is the

voltage above 11.9 VDC?

Battery Terminals 3 & 4

NO – Then the panel sees the new battery in a trouble condition. You can wait for the new

battery to charge to 12.6 VDC OR you can check the charging circuit…

YES – Replace AC wiring on terminals 1 & 2, remove battery leads from the battery. Check

DC voltage on terminals 3 & 4. You should see about 13.8 VDC (14.2 VDC max.) when the

battery is disconnected.

If you see less than 13.8 VDC, the panel’s charging circuit may be damaged, in which case

the panel will have to be replaced.

TECH NOTE: Any time the battery voltage falls below 10.2 VDC, the panel disconnects the

battery. This is to prevent deep-discharge damage to the battery.
