ECN Forum Forums Code Related Discussion Building Codes for Electricians Smoke Alarms / Smoke Detectors

I am looking for a short video on smoke alarms/smoke detectors and where to locate them in a residence. Maybe something that would show how smoke travels and/or why it does travel that way. I remember a video on flashover that I think would work but I can't find it. Thanks in advance. George

Personally I think making them accessible to the homeowner for periodic maintenance is more important than being able to catch every possible whiff of smoke as soon as possible. I properly working detector that takes an extra minute or two to detect the fire is better than one in the perfect spot but is inoperative and was never tested or serviced.
