People do not often take note of these small circular devices attached to the ceiling or square ones on the wall. These are devices that you probably have not touched at all, except when you needed to change the batteries. Or when you needed to check whether it was working or not. Whether you know what they are therefor or not, smoke detectors are actually life savers. They are usually connected to a fire alarm that sets off an audible warning when triggered, or to the automatic sprinkler system if you happen to have one installed in your house. In countless instances, smoke detectors have given ample time for home or office occupants to escape before the fires could do greater damage. They have certainly saved lives. Having a smoke detector warns a house occupant early on that something is burning and needs to be put out. Now, the saving part depends on whether or not you have the tools and equipment to put the fire out or whether your fire department is quick to respond to such an alarm. You also have to be alert enough to either try to put out the fire yourself or call the fire department immediately.
