Triac dimmer after PIR sensor

[Fiftyhertz]

Hi there,

I am looking at specifying a Triac dimmer switch after a PIR and manual override to control several lights, i dont see an issue why this shouldnt work as the Triac dimmer is after the PIR. Has anyone done something like this before and had issues?

I know its a bit unconventional but should achieve what the client is after.

Thanks

It will work fine as long as the pir is a relay type one.

Thankyou for the reply. Sorry, what do you mean a relay PIR? Could you send a link as an example?
Thanks again
