When I moved into my new house there was already a security light fitted at the back which is very handy when coming home after dark. However it got switched off once and now when I switch it on it stays on permanently.
The other night I switched it on and went out, when I came home it was off, but sensed me and turned itself on, but later on I noticed that it had stayed on since then. As it has been there longer than me, I have no instructions for it.
Anyone have any ideas as to how I can get it back to being a sensor light?
I thought it was the other way around. You did the on-off-on thing to STOP the automatic mode and force it permanently on. So the default operation (and, coming back on after a power cut) was the sensor mode.
The OP did say that it was off, sensed him and came on, but stayed on.
When I've gone to the switch and some 'mysterious' person has turned it off (Mr Wilsarnie ALWAYS maintains it's not him but really who else could it be when we live on our own??!) I just flick it up down and up and then it works in sensor mode.
I know it might be a daft answer to your question but have you tried cleaning the sensor with a damp(not wet) cloth?
I've had a similar prob where the blasted thing wont go off and did the above and it worked.
If you've already tried this,please forgive me.
For this problem you should contact with your installer. He will sort out your problem. Instead of that i will suggest you to put video door phone. It will record all the actions in your premises. It is a reliable solution for security.
