Smoke alarm technology has been around since the 1960s. But the
single-station, battery-powered smoke alarm we know today became available to
consumers in the 1970s. NFPA estimates that 94% of U.S. homes have at least
one smoke alarm, and most states have laws requiring them in residential
dwellings.
Facts & Figures*
15 of every 16 homes (94%) in the U.S. have at least one smoke alarm.
One-half of home fire deaths occur in the 6% of homes with no smoke alarms.
Homes with smoke alarms (whether or not they are operational) typically have a
death rate that is 40-50% less than the rate for homes without alarms.
In three of every 10 reported fires in homes equipped with smoke alarms, the
devices did not work. Households with non-working smoke alarms now
outnumber those with no smoke alarms.
Why do smoke alarms fail? Most often because of missing, dead or
disconnected batteries.

Safety Tips:
While smoke alarms alert people to fires, families still need to develop and
practice home fire escape plans so that they can get out quickly.
Install at least one smoke alarm on every floor of your home (including the
basement) and outside each sleeping area. If you sleep with the door closed,
NFPA recommends installing smoke alarms inside the room. In new homes,
smoke alarms are required in all sleeping rooms, according to the National Fire
Alarm Code.
Because smoke rises, alarms should be mounted high on walls or ceilings.
Wall-mounted alarms should be positioned 4-12 inches from the ceiling;
ceiling-mounted alarms should be positioned 4 inches or more away from the
nearest wall. On vaulted ceilings, be sure to mount the alarm at the highest point
of the ceiling.
Smoke alarms should not be installed near a window, door or forced-air register
where drafts could interfere with their operation.
NFPA recommends that people with hearing impairments install smoke alarms
with louder alarm signals and/or strobe lights to alert them to a fire.
Be sure that the smoke alarm you buy carries the label of an independent
testing lab. For a list of manufacturers that distribute smoke alarms for the
hearing impaired, please call NFPA´s Center for High-Risk Outreach at +1 617
984-7826.
Alarms that are hard-wired to the home's electrical system should be installed by
a qualified electrician.
Smoke alarm maintenance
Test smoke alarms at least once a month, in accordance with NFPA 72, National
Fire Alarm Code®, by using the alarm's "test button" or an approved smoke
substitute, and clean the units in accordance with the manufacturer's
instructions.
Install new batteries in all smoke alarms every six month, for example, on the
day you change your clocks or when the alarm chirps (warning that the battery
is dying).
Replace all smoke alarm batteries immediately upon moving into a new home.
Keep batteries in smoke alarms; do not borrow them for other purposes.
Nuisance activations can be addressed by moving an alarm farther away from
kitchen smoke or bathroom steam and by more frequent cleaning. If the problem
persists, replace the alarm.
Replace smoke alarms every 10 years.
