ANY-help Please

[gooner59]

OK i have put a false ceiling in my cloakroom with two hispec 240v- 11w downlight's which are wired correctly ,i then bought a Luxomat Occupancy sensor that i have tried to wire to the switch wire all on the live side ! the Luxomat has three terminals LL'N WHATEVER COMBINATION I TRY it will not switch the lights -on :frown: Any ideas please? when i take the switch-wires out and touch them together the lights come-on !! look forward to you repies guys .......

Picture?

You got the Lux and Time settings correct on the sensor? You got the housing removed from the actual sensor (sometimes comes fixed to narrow/shorten the width and range of the sensor)

Could be the fact that it's just too bright to work when you're trying it.....

Does this sensor also require a neutral? Have you give it one?

 

[telectrix]

have you got a neutral to the sensor?

Follow the manufacturers instructions to the T including setting up .... majority of things don't work correctly because people fail to do the simple task of reading the instructions.

If the 11w lamps are cfl then using an occupancy sensor is a bad idea you will be seeing drastically reduced lamp life to the point the cost of replacing lamps will out way the energy you may save by the lights auto turn off when unoccupied.

Good point Tel' although their are sensors out there that don't require Neutral some use the light as a false N when not switched but come with a minimum lamp rating to operate and others have a battery to do the switching and sensing,

What telectrix said! Even though it's a switch, almost all pir's need a neutral for the little led that flashes when it picks up movement amongst other things!

Yes mark i get the wife to set the sensor as she has more patience ( should be perfect LOL ) i have the terminals exposed , when i first touch the live on the terminal the lights flicker then go-off ......

Sorry didn't see these other replies ! and No i don't have a neutral wire to this unit !! this could be it !! Oh ship ,how can i get a neutral to it without breaking my ceiling -up lol

 

[Octopus]

This should be in the DIY area

As I said above if the lamps are compact fluorescents then don't bother with the sensor ... back to the drawing board and yes as Murdoch noted its clear your not an Electrician so please post in the DIY section not here.

 

[gooner59]

Sorry but i'am a tiler from the tilersforum, and don't know your rules ! will post in the diy forum next time guys.....thanks for your help....

 

[Pete999]

Not had any experience with these before, don't suppose it's Live, Switched live and a neutral is it? as with most stand alone PIRs.

 

[Wiresandthings]

Most certainly a lack of neutral is your issue, installed a lot of luxomat sensors recently and found them very good for setting up etc also if anybody uses Wf senate, some of there own range sector sensors are rebranded luxomat ones and cheaper

Thread now in the DIY forum.

Can't you just pull a 3 core & earth through from your lights to your PIR? The cores will then be permanent live, switched live and neutral.

First of all, as has already been mentioned, make sure your two hispec 240v- 11w downlight's are compatible with PIR's.
Looking at the Luxomat Wall Occupancy sensor web site, they need a neutral wire. So you need 3 wired going to this sensor.
As HandySpary has mentioned, can you pull a 3 core through from your light to the wall sensor? How is the cable going to the switch? Has it been plastered in or is it in tubing of any sort?

 

[gooner59]

Thanks again guys ,i stripped a neutral wire from a m-lenth twin&earth, then took a neutral from the lamp close to the pir and connected, and now it's running great . i did two years of an electrical apprenticeship , then jacked to earn some real-money plastering/tiling lol thank's fellers ....

 

[Spoon]

I wouldn't have stripped the neutral out of a twin & earth. You lose the protective measures of the outer insulation. Just get some twin and earth and just use the neutral. Don't strip it out.

Glad that you are earning more money doing plastering/tiling. You should tell more people... everyone... then we won't have every muppet joining out trade thinking that they earn loads of money by sticking two wires together.
