pir in garage

scott 123 · Apr 21, 2015

customer wants 3 fluorescents in a garage to work off both a p.i.r (when door opens) and a switch can this be done or can he only have 1 or the other (existing power already there and all good)

think you'll have problems triggering florries with a PIR. a switch on the door might be a better idea.

Does he want the switch to override the PIR so he can keep the lights on whilst he is in the garage? seems a daft idea really, just put a limit switch on the door. Door opens lights on, door closes lights off simples

or limit switch on door and a manual switch in parallel so he can have lights on with door closed.

sorry should of said he uses the garage as a workshop as well, so wanted to override pir with switch with door shut

What about just putting the lightswitch next to the door like we usually do?

you can have a suitable pir and switch wired in parallel. Ideally you would set the run time on the pir for a longish period so not to keep switching the fluorescent all the time.

edit: is the garage big enough to warrant both?

I wouldnt think installing lighting on a PIR in a workshop is a good idea.

scott 123 · Apr 21, 2015

best idea i have is 1 circuit for switched lights with seperate light with a PIR

This is straightforward.
You can have the lights come on on a PIR and have a manual override switch that will turn the lights on permanently.
You have to remember that when you switch off the manual switch the PIR will take over so they will not go off at once.
Other options are possible.
