Moved into a new house with Scantronic 9452 System that appears to work except two of the PIR detectors. They both have the LED on all the time. Got any clues?
is this system hard wired, or wireless, if its a wireless model each pir's will contain a (pp3) nine volt battery, I think that when the led is permanently showing on its a visual device indicating low power to the pir the pp3 battery needs replacing in the affected pir ,go for the good duracell type battery.
