Two-thirds of all fires involving fatalities happen in homes between the hours of 8 p.m. and 8 a.m. Three-fifths of America's home fire fatalities occur in homes without smoke detectors.

A smoke detector can't save your life if it's not working.  Dead, missing or disconnected batteries are the principle cause of non-working detectors.  Test your smoke detectors once each month and replace any battery too weak to sound the alarm. Heed the warning, when the detector chirps, the battery is low. Replace batteries once per year on the same date (your birthday).
