New PIR in Toilet

[Jacka]

Hi all

I've just bought a PIR to replace the pull switch in my downstairs toilet.

I've taken it out of the packaging and the wiring block has Live (L) , Live out (L out) and Neutral (N). With my current wiring I only have Live and Live out. Do I need to replace the wiring to the switch or can I just connect using the live in / out.

Thanks for any help

Jacka

It won't work without a neutral connection.

You need a neutral connection, and it's unlikely that one is currently available at the pull switch - so, as you say, some changes to the wiring may well be required.

In passing, are you sure it's a good idea? People have been known to be quite still for significant periods of time in toilets, in which case they could get plunged into darkness if the light is controlled by a PIR!

Kind Regards, John

Danlers and others do PIRs that do not require a neutral.
Google "Ceiling PIR No Neutral"

As a matter of interest, do they necessarily all work with anything other than incandescent lamps? (they need to be able to get a little current through the load when it is 'off' in order to power the electronics)

3-core, and earth as well, I hope!

Of course. brown live in, black live out and grey is neutral?

The usual colours used are:
Brown = line in
Black (with a brown sleeve) = switched line out
Grey (with a blue sleeve) = neutral
CPC (with a green&yellow sleeve) = earth

I doubt you'll ever come back and admit it, but I promise you that having a PIR will drive you mad, and that in a few months you'll remove it, go back to having a switch, and curse the day you ever put it in.

Youre probably right, it's in now though and seems to been fine
