rear door entry sensor

​I love my system. Recently when arming the system to leave, I get a prompt telling me warning back door sensor open. The door is closed & locked & the sensors seem to be aligned properly. Any ideas? Thanks​

Hi @woodrow51 ,

The Entry Sensor is very simple, so the only way that it could show as "open" is if it has lost contact with its magnet. So checking if the sensor is properly aligned is a good call, but you'd also want to check that the two pieces are not more than 2" away from each other.

And since, as I mentioned, the sensor works by detecting a magnet, placing it on a metal surface (like iron or steel) may impact its function. If you have one of those steel fire doors, or something similar, you might want to put some padding under both pieces - maybe a piece of wood or plastic, or even just an extra layer of adhesive.

I have the same issue with my back door sensor. Works OK for a few days, then shows open all the time for a couple of days then all OK again and so on.

The sensor chimes when the door is opened even if the system is showing that the door is open.

Any ideas? Cheers
