I have two security lights, triggered by PIR sensors.
They work fine most of the time. However, if we have an interruption to the power supply, then power is restored, they stay on permanently.
I seem to recall that the solution is to switch them off and on again (once or twice, I'm not sure), then they'll start operating as normal. However, I'm trying this at present, and it doesn't seem to be working.
Any suggestions?

hi ya when the power has been off, then on again sometimes the lights go into a testmode, they should only stay of for the time duration they are set on when they are operated from the pir. then after a while they should reset themselves and go back to ususall.

It is my understanding that the lights go through a self-test sequence after a supply interruption. I think it takes about 10 minutes.
