SMOKE DETECTOR SAFETY
Test your smoke detectors at least once a month. Most detectors have a "Press to Test" button. A broken detector provides NO protection and you can't afford to be without early warning to a fire.
If your detector is battery operated, change the batteries once a year as a minimum.
You should have at least one smoke detector on each level of your home or apartment. The protection of sleeping areas is very important, since most fatal home fires happen at night.
Train everyone in your family to respond quickly at the sound of the smoke detector. Second's count ... practice getting out safely.
