2 Floodlights and External PIR wiring ?

[Rake722]

Hi all,
I’m trying to figure out how to best wire up 2 30w LED floodlights with external PIR.

I want one on the front wall of the house and one on the side wall at 90 degrees from the front.

The spark who began the job embedded 2 wires in the render on the side elevation, one wire to the consumer unit in the adjacent garage and one wire going up to the eaves and left a long tail.

I was thinking to connect the mains CU to an adaptive box where the 2 wires come out of the render together and the other wire to the PIR on the front of the house and then PIR to another JB under the light on the side elevation then out of the JB to the front flood light but that seems to add more wires going around the corner.

Can I come off the mains to the JB on the side wall then JB to side flood then side flood to PIR on front then PIR to front flood light ?

Thanks in advance

A bit hard to follow that

Front wall and side wall siting

So probably 2 pirs or 2 30w sensor lights needed ?

Thanks for the reply, let me clarify.

We need one floodlight on the front wall and one floodlight on the side wall.

There is one external PIR to go on the front wall.

On the sidewalk there are two wires chased into the render one of which goes to the mains and the other goes up the wall to the eaves and there is a Tail hanging.

I need the one PIR to activate both lights.

So I was thinking of installing a junction box on the side wall where both the wires emerge together, using one wire for mains supply and the other to go to the PIR and then connect the floodlight on the side to the PIR at the front and daisychain the front floodlight to the side floodlight.

Is there a way of doing this without having two wires going around the corner from the side to the front?

Still can't picture it. A drawing or two would be useful.

Bear in mind that the rules for concealed cables apply outdoors as well as indoors.

Run the cable to the PIR connector then a second cable from the same connector to the LED at the front. From that connector run a third cable to the LED at the side.

I used to run two PIR Flood units together and wired so that either PIR would activate both flood’s simultaneously. If the particular PIRs are capable of running the total load and the output of each is switched via a relay not a semiconductor then it’s easy. If not it’s more complicated. Could be set as individual PIRs by using a removable link or even a switch. Unfortunately nowadays the connection for PIR and Floods are done internally so separating them might be difficult.

It's a little odd the sensor only on front. No lighting at side if you're coming from back of house .
Customer probably knows his requirements anyhow

The post clearly states that we want light on the side and on the front. The PIR would have to be on the front to Pickup movement effectively.

Don't think you understood my point . Anyway if you know your requirements that good enough.

So cables are buried in the wall without being in safe zones, and pop out of the wall nowhere near where you want either lights or PIR?

So it seems. Hence the question how to do this as neatly as possible given the circumstances.

WTF was he thinking?

Is there an option to start afresh and discard existing wiring?

Yes.

I could snip the wires. The one emerging at the top would not be visible from downstairs however the ones emerging lower down I would have to put a vent over them or something to disguise it but yes, the option is there.
