Alarm problem - emitting a long beep in the middel fo the Night IDS 800?
our alarm keeps emitting a long beep in the middle of the night for no reason - it is armed at the time and then a zone flashes briefly and then clears. We rearm after checking the zone - find nothing wrong. Often it does it again once you go back to sleep. Please help
