The factory back up battery fails and will keep setting alarm off wry common and can fail that bad can cause a fire in the loom.

The garage i took my zafira A to when the alarm kept activating simply removed the power sounder . I didnt find this out for a long time. It was the garage i bought my car from and it was still under warranty and i guess they thought it would be easier and cheaper for them to fix and i would be non the wiser. And i wasnt for a long time .



However the alarm still went off randomly. I managed to trace the fault to the rear side window glass break sensors. I bypassed these by disconnecting the wiring plug from them and putting a big blade fuse in their place. This completed the circuit and stopped the random alarms.

Afaik there’s an option in opcom/tech2 to shut off the power sounder and put it to the car horn instead
