Scantronic 9448+ Sensor Fault

[JackCarter]

Hello,

One of the door sensors on my alarm only activates intermittently. Sometimes it works and sometimes not,. The cables to the sensor look ok, the sensors are undamaged and not misaligned. Inside the console the cable interfaces look ok and I see no signs of burn out on the PCB.

Any suggestions what this could be or what to try?

Change the contact!

Change the contact!

Short and to the point

Couldn't be more correct though.

The contact 'sticks', someone breaks in, don't need to say any more.

They only cost a few quid.
