Trying to fit a PIR switch

[martind]

I want to fit a PIR switch in palce of a bathroom pull switch (to stop the kids leaving it on all the time)

The PIR switch I bought from Focus has wiring instructions which say that there should be 2 lives and 2 neutrals, however the old pull switch operated from only 1 live and neutral.

I have tried to wire up using only one of the lives and neutrals in the PIR% but it doesn't work.

Anyone got any ideas ?

The switch will normally have one live, and one switched live. No neutral. You would need to import the neutral from the light position for the pir to operate.

Part P of the building regulations applies though as you will then be altering the fixed wiring in a special location.

Might be easier docking the kids pocket money for a couple of weeks till they get in the habit of switching the light off to be honest!

What happens when you fall asleep in the bath, incidently?

As Harvey has said the PIR is not a direct replacement for your pull switch.

Most PIR's are 3 wire, live, neutral and switched live to the light. A copy of the wiring diagram would be helpful, can you scan it, re-draw it?

And in the meantime, fit compact fluorescent lamps.

I was just wondering if a delay switch would do the trick, sort of thing used on staircases in blocks of flats, used to be pneumatic but I think I've seen electronic ones.
