Did a 'like for like' security light swap last week. Removed the old (no PIR) light, just a red & a black wire coming through garage wall. Volt stick said there was current. Remove fuse.
Fitted new light with PIR, restored power, nothing happened. Checked wiring inside light, still nothing but volt stick still glowing.
Customer then 'remembered' that the old light operated by a switch in the hall, switched that on & all worked fine.
Called me yesterday to say the manual override feature didn't work. With all the PIR lights I've seen, flicking the switch on/off rapidly sends them into manual mode, so they stay on.
I'm assuming that the switch is just breaking/making the neutral - haven't seen the switch wiring yet. Is that a likely cause?
If so, any simple solution, rather than rewire the lot?
