ok...this is the principle of a seismic detector...you see on 2 parallel rails, two counterweights...when they meet...the alarm fires...what the PIR relay is doing is controlling the capacitors...right? ...so, my idea, goes, to capacitors are burn...the alarm is burned...or...you have to invent a counterweight connection...like...putting a 50 kilos weight on one side up the door...and another down on the opposite side
