What smoke detectors can do:
Smoke detectors are designed to provide early warning of developing
fires at a reasonable cost. They monitor the air and can sense smoke and
can provide precious minutes for you and your family to escape before a
fire spreads.
Caution: Early warning fire detection is best achieved by the installation of
fire detector equipment in all rooms and areas of the household as follows:
A smoke detector installed in each separate sleeping area (in the vicinity,
but outside of the bedroom), and heat or smoke detectors in the living
rooms, dining room, bedrooms, kitchens, hallways, attics, furnace rooms,
closets, utility and storage rooms, basements and attached garages.
What smoke detectors cannot do:
Smoke detectors will not work without power. Battery operated detectors
will not work without batteries, with dead batteries, or if the batteries are
not put in properly. AC-powered detectors will not work if their AC power
supply is cut off by an electrical fire, and open fuse or circuit breaker, or for
any other reason. If you are concerned about the reliability of either batteries
or your AC power supply for any of the above reasons, you should install
both battery powered and AC powered detectors for maximum safety.
