On the contrary, smoke detectors are placed outside bedrooms so that the occupants might hear the alarm in the middle of the night, when most home fires occur.

Not that this has anything to do with the original thread...but because it was being used as an argument, I thought I would clear the air. I am a member of both a CERT and a DART team and have had fire and disaster training. During our training it was explained why smoke detectors are placed in those locations.
