Hi,

the extension has been finished and I have realised that the
down-lighting at the front of the house would be much better if it was
on a PIR.

Its 12v lighting powered from individual transformers.

I've bought a PIR and wired it up to the supply to the transformers,
but it doesn't do the job. I've checked the PIR on a standard 240v
light fitting and it all works OK.

Is it problem with the resistive v. inductive load that the PIR is
looking for?

Can anyone suggest a solution?

Many thanks,


Matthew

You need one which has a relay switch, rather than semiconductor.
You should be able to hear the relay click on and off. Also, the
PIR will require a neutral connection (although that by itself
is not an indication that it is the right type).

Cheers Andrew,

The one I have "clicks" on activation, but fails to switch OFF again!

Can anyone recommend a brand that is known to work with 240v/12v
transformers?

Cheers,

Matthew
