Hi.

Weird one. I fitted a Georgian style PIR light outside the door of my house.

Got a 3 core flex cable (Line, Neutral and CPC) from board to 13A spur (fused down to 3A), then to light fitting.

When you walk by, it switches on fully bright, but when it switches off (a.k.a no movement) - it's still on, but MUCH dimmer, but always on. So basically I have BRIGHT ON or DIM ON!


Sensor is adjusted to full and time is 30 seconds. But changing this makes no difference.


Any help would be appreciated.


Thanks guys.
 
Yes.

But funnily enough -
Terminal layout is LIVE, NEUTRAL, EARTH and SWITCHED LIVE.

PIR lighting only requires permanent live because sensor does the switching. So..... what's switched live terminal for? Aha.

I connect BROWN to LIVE, BLUE to NEUTRAL, GREEN/YELLOW to earth. Switched live terminal has nothing connected to it.
 
some fittings have a dusk sensor which does this by design, might be worth checking it's not one of those first! I fitted some the other day which had a dimmer value and a timer (as well as the normal proximity, delay and lux controls) purely for a dusk setting.
 
If you've supplied it directly from the DB why did you wire it through a fused spur and not just a switch?

So are you saying:

Light is on dim throughout the whole night?

Then when it is bright during day should be completely off?
 
Definitely sounds like the one I've got on the front of mine, where the 'OFF' position is actually a half-brightness level. Probably working as it should. Daz

I think you are correct, thanks for clarifying.

Just still unsure what SW L terminal was for, that confused me slightly aha.

But cheers.
 
I thought the switched live was if you wanted it on permanently?
i.e controlled from the house?
a lot of modern ones have this feature by simply switching it on and off very quickly.
