Fitting PIR security light

Question

Paul 1982

I had an old grubby light fitted to the outside of my house. Not a security light just a normal light. I’m after fitting a new light to it, the light had a bulb holder style bit for wiring the live and neutral into (black neutral white live) no were for earth to go so put earth into terminal block with insulation tape around it. Problem is soon as I’ve put power back on the light isn’t going out or switching of at what I’m assuming is the switch for the light as it’s directly below it on the inside of house, can anyone help please

How many wires / cables are at the fitting, is it just 1 x twin & earth?

 

Did the old one switch off, or just never work?

 

Has the inside switch been changed at any point?

 

Cheers

Yeah just 1x twin earth

 

When we moved in it was just not working, maybe build was just burnt out, but fitted new one there and it’s constantly on. 

 

Theres a new chrome single switch fitted pretty close by which I though it was maybe being powered from but opened it up just there and the cable that’s being wired into light isn’t to be seen behind switch. 

So confused

Are there any other external lights along same wall of property that this one maybe linked too? It maybe that the switch is elsewhere if there are.

Hmmm, ok. Did you say you have had the switch off the wall? what does that  look like inside (Disclaimer, don't die or even attempt if your not confident. Advise turning power off first).

 

Does switching the switch do nothing, anywhere in the house?

 

It could be that the swithch is for the light, but connected wrong.

You need some test kit, some paper and a pencil IMHO

It may also be that the switch for the light is infact a scarlet fish, and that the light that was there had either a PIR or a photocell built in and so does not need to be switched off.

Thanks for all help, I’ve now traced the cable , its going to the single switch in my kitchen, although the single switch doesn’t seem to switch it on of. Maybe wired wrong? Should there be a double switch, one to control outside whilst the other controls the kitchen light?

Hey guys, I have a fuse box in my garage, a breaker on it powers a constant light on the outside of my garage. Can I remove the old lamp and replace it with a pir security light. So when nothing’s there it’s of but once movement happens it lights?

Hold on a minute Paul, this outside light that you originally spoke of- is that the same as the one outside the garage you speak of?

what does the switch in the kitchen switch? Kitchen light?

Hi sorry I didn’t realise I’d continued a different topic on this other topic. I was meant to create a new topic. No it’s a different light on garage running straight to fuse box, would a PIR work on that cable running direct to my fuse box? 

 

Yeah in the kitchen I have a double dimmer switch controlling both ceiling lights on other side of kitchen I have a switch that puts one of the kitchen lights on and off, this is the switch that outside light is wired to and is constantly on wether switch is on or of ? 

There’s about 4 cables roughly in this switch

 

I’m not bothered at all with it being able to control one kitchen light as I can use dimmer for this. I’d like the switch even to just be used for outside light only, is this possible cheers

Ok so first things first, the garage, you can change the garage light for a security pir light, be sure to isolate supply first. 

 

Now on this kitchen switch have you a photo of it or is it the earlier photo? If

Do your kitchen lights work ok when switching?

Yes double dimmer switch works fine

 

And the single switch that outside light is wire to works fine to kill one ceiling light

 

Not sure why single switch would only kill one ceiling light and not both

When you say the outside light is wired too, have you confirmed that? If so what terminal does this wire go into?

Yes I have confirmed that

 

I’ll need to properly make sure I have the correct cable out of the 4 tommorow and I can say exactly were there going to on the switch. 

 

does it sound like a normal situation , 4 cables going into that switch, well 3 then the 4th going to outside light

For a start, if that switch does the kitchen iight too, then surely you will need to change it to a 2 gang switch?

It does appear to be a single Gang switch, perhaps why the outside light has constant power.

It is a single gang switch, so I should switch to a double then? Sorry I’m obviously not as clued up as the person that fitted the switch in the first place. 

 

Can I adjust the wiring in the single gang for it to only work outside light as not to bothered on it working the kitchen light that it does just now.

 

If not have you any tips on how the two gang should be wired up when installed 

 

cheers again for the help
