Putting the smoke detectors on a seperate circuit so they can be turned off? IMO this is STUPID! A smoker turns them off so they can smoke, then they fall asleep and the cigarette drops into the couch and smolders until it causes a fire and possibly a death? Isn't this what they are designed to prevent?

BTW, my wife smokes and no the detector has not gone off from her smoke, now the cooking is another issue. LOL.
