A few decades ago our fire department fought a fire where a young teenage girl faced serious injury and death and just by pure luck escaped. The smoke alarm in the front room of the house went off faithfully in response to the kitchen fire she started by leaving a pan on the burner and forgetting it, but the girl had gone into her room and turned the stereo up loud and promptly forgot her tomato soup, and never heard the smoke alarm go off. If the alarms in the house were interconnected (unusual in those days) the one in her room would have gone off and she would not have had to be pulled out the back window.
