Hi all,
I had a very old outdoor PIR (Smiths, no model number) connected an LED floodlight, which is also linked to a one way switch. The PIR seemed to have failed as the light only flashed on when it detected movement (no ability to adjust time on).
I have got a Knightsbridge OS001 to replace and have done so with the wiring like for like. However, the issue I'm having is that the light stays on (in daylight) at half brightness at all times. When I use the switch to override in the on position the brightness increases, and reduces again when I turn it off. I have tried flicking the switch off a few times to push the PIR into auto mode, to no avail.
When I take the PIR face off of its backing, the LED light goes off and still responds to the switch.
Any ideas what I've done wrong here? Thanks!
