Front door contact sensor missing


Recommended Posts

My local dealer is closed today and this isn’t urgent, so asking here.


We have a concord4 alarm integrated with wired recessed door sensors. I just noticed our front door sensor is missing from the door jam. What’s interesting is there’s not the typical magnetic end on the door itself so this appears to be a single piece or possibly some sort of spring sensor that must have broken or got pulled out.


I can see in the door jam hole there appears to be a small piece of metal and if I move it with a small screwdriver it triggers the door open / close. When I did this I also noticed some small crushed glass inside the hole so clearly it got smashed.


Anyone know what piece this might be considering it’s not the typical two piece magnetic contact sensor?5ef3f17edefc2be3e42e1a2ddb82fb6b.jpg
