PIR Light

[charlie_parker]

When i double switch a pir light it stays on until

a) its switched again
b) dawn

if i double switched, say before I went on holiday, would the light come on at dusk every evening until I returned? Or would it reset itself after the first night?

thanks a lot

It will probably just reset the following day, tho not 100% sure, this is when you wish you hadn't thrown those instructions out
Can you not do a "dummy run " before you go on holiday and see what it does

It'll probably reset after dawn - and I doubt this is in the instructions.

What wattage is the PIR light?

 

[charlie_parker]

150w - and you're right the instructions doesn't mention this. A customer wants to be able to have a normal pir controlled light but be able to switch it when he goes away so it comes on after dark. Not sure if the photocell overrides the pir.

Usually when you overide it to come on manually it resets back into automatic mode at dawn.

I have a hi-lo light which can be set to come on at dusk at a pre-determined brightness (form 0 - 100%). If the PIR is then activated it will turn to 100%.
