Negative Positive
Title: False alarm
Review: Carbon monoxide detector went off. I called, had the fire department come out and check. Nothing. Went off several times Even after replacing the batteries. This unit was properly reset by the firemen. I would suggest going with a digital read out. Not worth waking the neighborhood in the middle of the night and having to drag out the volunteers for a false alarm. Spend the extra $20. I wish we would have.
