I have a 16 years old TS690R alarm that was disarmed by an engineer when I had all windows and doors replaced, thus removing all contact pads. I thought the system was disconnected but when the electricity trips, because of a storm for example, the external sounder goes off and light flashes. I have tried taking the battery out of the control panel and fuse out of the box above the panel but this doesn't stop it. Is there a back up battery in the external unit? Most power cuts seem to be in the middle of the night and I can not do anything to silence the alarm. It only stops when the power comes back on! Can anyone help please?
