Why smoke detectors? Why not heat detectors?
Smoke and deadly gases tend to spread faster and farther than heat which is why an operating smoke detector is so important to have. More people die from the effects of smoke and deadly gases by a margin of 2 to 1. A smoke detector will automatically sound a warning when they sense smoke or other products of combustion. When people are warned early enough about a fire, they can escape before it spreads.
