4 wires to 3 wires on a pir floodlight help

[jpuk]

I decided to change our outside pir floodlight for an led one as it's 20 years old problem i have is there are 4 wires going to a terminal block earth,red,blue,yellow but the new led light has only 3 wires blue,red and earth hw do i wire it up here is a picture of the old wiring.John

that gave me a shock at first.

Leave the yellow disconnected and insulate. It's an override

Leave the yellow disconnected and insulate. It's an override

... or possibly a PIR-switched feed to another light?

Kind Regards, John

took yellow out but not working,forgot to mention there is a switch in the garage for this to turn it off and on ,John
This is the new pit light

 

[AndyPRK]

I'd check your connections.

Are the screws pressing on the bare copper wire ?

 

[jpuk]

No the earth sleeve came off,i'll put it back on before I fix it all in,john

 

[AndyPRK]

on the red , blue and brown wires I mean

 

[bernardgreen]

In the lamp one of the White wires must connect to the Blue ( Neutral ) wire and the other White wire must connect to the Red wire ( Switched Live from the PIR sensor ) Are those connections made ?

 

[AndyPRK]

I thought that was the old
Light and pir

In the lamp one of the White wires must connect to the Blue ( Neutral ) wire and the other White wire must connect to the Red wire ( Switched Live from the PIR sensor ) Are those connections made ?

What about the yellow wire?

 

[bernardgreen]

What about the yellow wire?

As mentioned before it is either

(1) an override circuit to allow a switch in the house override the PIR and turn the lamp ON.

(2) a supply to another lamp that is also cpntrolled by the PIR sensor

Put it into a separate ( 5th ) terminal block with nothing else connected to it.

The white wire is in the old pir. So do I have to get a fresh wire from the blue to the red wire ? John

 

[bernardgreen]

So I have to get a fresh wire from the blue to the red wire ? Johm

NO You must NOT link the Blue to the Red That would be a short circuit connecting Live to Neutral

Did you have a lamp with a built in PIR sensor and now you have a lamp without a PIR ?

If yes then how will you control the new lamp ? If this is a switch then can you take a photograph of the wiring to that switch. Turn power off at the consumer unit before you open up the switch.

 

[jpuk]

ok the old lamp was pir with a switch in the garage and the new one is led with pir,John

Is that wire you connected to the bare earth wire green and yellow, or just yellow?
