    Electrian told me he couldn't do it as wiring is old. Need sensor with room for wires from wall. Or that is best interpretation I can give. He didn't know where i could get one

    Anyone know?

    Apologies maybe I have misread your post. This is my interpretation:

    So essentially a qualified electrician has expressed concern about the wiring currently in place and on that basis advises against modifying it? But you have have decided to disregard that advice and take it on yourself?

    My suggestion would be to get a professional to replace the old wiring with new and add the PIR while they are at it. Replacing a PIR and adding more is quite straightforward.

    Hi, thanks for answering. Not at all in regards to ignoring. I had a PIR sensor bought and he tried to attach but said it would not work as they are very different to old PIR.

    As a solution is was saying to have a small box where PIR sensor would be and then sensor next to box or new sensor with enough room for wires. My interpretation was something about no room for wires on new PIR but coiuld be wrong I have no idea about these things

    I asked him which PIR sensor should I buy and he said no idea so I said I would ask here before attempting to buy new one

    In total there are 6 wires coming out of wall. The light is around the corner so all 6 wires are for sensor.

    There is brown and blue coming from one wire/sleeve and then brown, blue, green and yellow coming from another wire/sleeve.

    So alot going on for a sensor?

    Sounds like a low voltage PIR or PIR for an alarm.

    Can you post a picture

    Ok, sorry for the misunderstanding.

    I would guess that the 6 wires are:

    Live in, neutral in, earth in and then then live out, neutral out and earth out. A few simple tests would verify this. Easy peasy…

    Most wall mounted PIRs with the correct rating would be suitable. This is pretty basic stuff for an electrician to ask.

    Yes I guess his problem was too many wires for current PIR sensor so could not fit to wall so i needed specific one

    Thought it might be common problem but i guess not

    Mount one of these for the terminations and then fit the light beside/above and connect into that
