Presumably you knew all this when you bought & installed
the wireless system?

Yes,and I change them every two years but for this one PIR
which is 6 monthly, but hopefully now solved.



You could also perhaps reposition it or change to another
sort of sensor - magnetic contact?

He's using wireless. How will wireless magnetic save a lot
on batteries?


What's using up the batteries in the PIR?

The radio transmission signal is likely to draw several times
more current than the PIR sensor in stand-by.


So what's using up the batteries in that particular PIR more
than the identical others that the OP has?

The repeated transmission.


So... how to reduce the number of repetitive transmissions?
