I think the last thing any parent would do is hear the fire alarm, get out of the house, and leave the kids to fend for themselves. You work together to make sure everyone is safe. I dare say most parents would charge right into a flaming room to get their kids out, contrary to all fire department recommendations.

I know my wife and I bolt out of the bed for even the chirp of a low battery alert, let alone a full going off of the thing. My daughter gets out of bed and yells "Shut that thing off!" My son stays in his bed, unless it's the one in his bedroom that's going off. We have detectors in every bedroom, every hallway, every shared living area (familyroom, livingroom, office, etc.), and in the basement and in the garage. We have upstairs and downstairs CO detectors as well. A fire in our house, while devastating, would probably be anything BUT quiet!
