Why are smoke detectors really useful?

You think smoke detectors are there to alert your neighbour to call the fire fighters team when you are not at home? WRONG. Most of the fires occur between 2am and 4am while you are alsleep. So next time you are tempted to disconnect a beeping smoke detector because your food is burning on the stove think about all the deaths caused by fires when people are asleep and change that battery. But often help from a professional electrician is needed since most of the modern smoke detectors are connected to the home wiring system.
