Bathroom lighting PIR with override?

[dilalio]

Hi all.

Currently fitting out an ensuite that has secondary ‘mood’ lighting in niches and also three wall lights... want to put these on a PIR (or broken beam) switch so that they are automatically switched on during the night when someone enters.

Is there a way to implement this so that it can be overidden with a switch?

My thinking is that when occupied, there will always be movement so PIR will be continually activated... there’s no bath for someone to remain still in, and it is only the mood lighting.

Main downlights are switched traditionally.

Just thinking best way round this.

Many thanks.
Dean

Using two single pole switches to provide overrides for a basic PIR

Is it too hard for that someone to work a switch?

And what will happen during hours of daylight?

Cheers BG.

So that’s a 2 gang switch just for the mood lighting? Or could it be one gang for main spots and mood and the other switch brings the PIR into play? Does that mean user having to remember to throw switch into “night mode”?

Maybe, when half asleep and not wanting to disturb sleeping partner by accidentally throwing the switch for the extremely bright main lighting!

And what will happen during hours of daylight?

Ensuite is windowless.

The easy option is a standard two gang switch for controlling the mood lighting and a separate switch for the main lighting.

It can be achieved with a 3 position, centre off, double pole switch but as far as I know there is not a "domestic" rocker switch with that configuration.

No-one yet seems to have mentioned that if a 'standalone' PIR is contemplated, many of them have an over-ride facility which is impolement by (fairly rapid) on-off-on operation of a switch supplying power to it.

However, as always, it's worth saying that attempts to use PIR-controlled lights indoors commonly drive the occupants mad fairly quickly!

Kind Regards, John

You will be surprised.

Thanks John. (And others).

Yes, I have outdoor PIR’s that have the on-off-on override and never use it so can’t see customer accepting that either .

I wanted to investigate this but was of the opinion that simple switching would be best and your collective inputs have corroborated that

I/they don’t need the grief
