If you still have problems you must ID what detector is causing the problem. Good luck.On second thoughts will try in the morning , me , the dog and my friend the baseball bat should keep us safe tonight.
No it’s the magnet on the door contact. The magnetic switch on your door frame is controlled by the magnet on the door. When the magnet is close to the door when the door is closed the switch is closed, When you open the door you take the magnet away opening the switch. The battery will be within the switch on the door frame. The battery will probably be a coin shaped battery.Update , false alarm again yesterday so checked what I believe to be the battery. Is this the battery ? It is strongly magnetic and there does not appear to be any terminals. Having difficulty finding a replacement so any help appreciated. Meanwhile have disabled sensor by removing magnetic battery and no further false alarms.
This will be a process of elimination.We are suffering the same problem with false alarms sometimes within minutes of setting and sometimes after a couple of days! replaced main van battery and also the small coin type batteries but still cannot find the fault![]()

Remove the batteries from each detector one at a time until the alarm does not go off. By removing the battery you stop the detector from sending a signal. Rarely are detectors supervised on car systems, so this should work. The chances are it’s one of the detectors that has went into fault condition. just to confirm if you have identified a sensor as causing it put the battery back in, if the alarm goes off then you know for definite it’s that sensor. Of course it could also be a faulty receiver within the main panel. But this is well worth a try.
