Title: Going off for no reason...in the middle of the night
Review: We purchased these for our home a little over a year ago. No batteries would make one think that no in the middle of the night awakenings to screeching alarms or annoying beeps...not so. No smoke, no fog, not a thing to cause the noise to wake the dead, yet awake we were. Had to completely disconnect the entire unit from the power source. not a detector I can recommend.
