The main lighting is 347 volt, so I added some 120 volt lights and put motion sensors on each end of the hall. One motion sensor is already dead. Drat!

347 .. that's an odd tap .. I've only ever come across 277 for single pole lighting, not to say it doesn't exist... but as my quote below states ..

I recently came up with a concept using basic UL approved technology which really is no big secret so patenting is not an issue, If anyone wants to patent it go ahead .. Atleast I can simply buy the kit instead of building it.

Anyway I provided a link to my video made some time ago for the heck of it, The issue in my area is rooftop theft stealing the copper from the AC's .. so I came up with a prototype generic concept but applied it to rooftops.

Motion sensors with lighting controlling a contactor which engages a horn strobe .. not foolproof but it does work, no units have been stolen sense.
