Guest Guest Posted April 9, 2006 Share Posted April 9, 2006 Raining? are you man or mouse get up there now with your torch! Should have done it yesterday its snowing now. I have checked the wiring and which bells through back down to the alarm panel and both the fron and rear tamper switches are operating. When the alarm panel os closed and the bell box is open it triggers as if there is a tamper and the internal sounder goes off. If i replace the bell box lid the alarm panel does not trigger as though there is a tamper and the internal sounder does not go off so i think the tamper switches are working ok In the alarm panel ar two terminals for the sounder 12v supply (D) and -ve sounder trigger. The onky way i can stop the bell is to remove one of these wires but there is a constant voltage on both these terminals. Should there be no voltage on the trigger until the alarm is triggered. The voltage is still there even in day mode. Link to comment Share on other sites More sharing options...
