I am getting a sensor fault on my DSC wireless door sensor, which has been working great for about 3 yrs.

I removed the sensor and tested the battery.  It seemed ok.  If the battery was low, I would expect a low battery signal, not a fault signal.

How do I debug the system?

  • Hi Thomas, 

    What is the voltage you got when testing the battery? What is the distance between the magnet and the sensor?

    If you open the sensor up and locate the reed switch (this is the tiny glass tube that the magnet lines up with) what does the switch show if you put your meter on continuity and place the probes on the metal parts on either end of the tube. Try this with the magnet nearby and away.
