Having had a major grease fire in the kitchen last year and a false alarm situation the year before and my invalid wife in the bedroom upstairs never hearing the smoke alarms I have been looking for an answer. I think I have found it with interconnected wireless smoke detectors. Additionally since I have a stove in family room as well as the basement office along with a computer equipment room down there that would run most ISPs I have always been concerned about a fire down in the basment. Today I installed wireless interconnected smoke detectors on all three floors and they are pretty slick. If any one of them goes off they all go off. Not cheap, $150 for three, and not foolproof but a little more peace of mind.
