    Hi all

    I'm hoping somebody can help me with the these PIR sensors that I have in my new house.

    They appear to work just fine yet the little signal light that I would expect to turn on when I pass any of these sensors doesn't seem to work.

    There are seven sensors in the house in total and not one lights up when I pass?

    Could they just all be fused or is it possible to turn these things off?

    Does anybody know the make or model of sensor so I could go off and find some extra info on it?

    Picture below

    Dont know the make but they could just have the LED off.
    Could be a dip switch inside the device itself.

    Hey all, I’ve actually figured this one out. There is a little jumper inside the sensor that needs to be adjusted to enable the LED
