4-LOM submitted this idea :
I've just got a 150W PIR security light from Wickes, but the "manual"
(sorry, I mean scrap of paper) isn't very helpful. I can see how to
wire it up to run on automatic all the time, with an isolation switch
to turn it off completely, but I want to know how to set it up for
manual override. The "manual" says "see later sections for manual
override wiring" but these later sections don't seem to exist. Which?
Guide just says "follow the instructions"!

Ideally I'd like to be able to override it manually from two different
places, which involves the added complication of two way swithing,
although I don't even know if this is possible atm.

The usual way (might work) is to briefy turn the light off then back
on, the light will then stay on until daylight overides it, or you
manually turn it off.

Turning it off, waiting ten seconds, then turning it on restores normal
PIR operation once the light has settled.
