Getting one PIR light to trigger another

[stealthwolf]

We have two outdoor lanterns. One is like this: http://www.wickes.co.uk/Wickes-60W-PIR-Wall-Lantern-Black/p/702846 and the other is like this: http://www.homebase.co.uk/en/homebaseuk/6-sided-black-lantern-with-pir-737685

(both similar style but difference in where PIR is located).

One covers the right hand side of the house and the other the left side. Each one only comes on if there's something that triggers the PIR.

What I would like is for both to light up if either one of them is triggered. Is this feasible?

 

[EFLImpudence]

Yes - but you will another conductor between the lights or via a common point.

As mentioned the only way to work this is to run a cable from one of the pir units to the next light fitting.

The PIR unit in that fitting becomes redundant.

Best situation would be a stand alone PIR central to the light fittings, and a feed from there to each light bypassing the intergrated PIR in each.

 

[EFLImpudence]

I think he still wants and needs both PIRs as they cover different areas but he wants both lights to operate.

Thanks @EFLImpudence that's what I'm after - both PIRs work and if either one detects movement, both lights light up.

 

[EFLImpudence]

Yes, you will need another wire between the two, though.

Is a wire from one to the other easy to fit? Probably not.

 

[stealthwolf]

Actually quite feasible. There's a feed from the fusebox to a ceiling rose. One spur goes to one light and one goes to the other. I reckon I could add a wire quite easily.

 

[EFLImpudence]

Oh right, that sounds lucky.

It would be better to replace the cables with 3 core & earth if you could do that.

Both PIR's need to be rated to the doubled-up load.

I may be wrong, looking at the light , im not sure you can access the pir wiring easy to do whats intended

 

[EFLImpudence]

The one in the second link is easily accessible

the first may be more difficult.

 

[stealthwolf]

the first may be more difficult.

The first lantern is the one I removed to have a look at the wiring. There's only live, neutral and earth wires. Nothing for switched live input.

Some lights are made like that, only LN&E terminals. It may be possible to access the switched live output, but you may need to partly disassemble the light to do it.
