SMOKE ALARM PLACEMENT (Cont’d)
Existing Homes:
• The NFPA requires a smoke alarm on
every level and outside each sleeping
area in existing construction. An existing
household with one level and one sleep-
ing area is required to have one smoke
alarm.
ADDITIONAL SMOKE ALARM
PLACEMENT INFORMATION:
•
If a bedroom area hallway is more than 30 feet long, install a smoke
alarm at each end.
•
In basements, install a smoke alarm on
the ceiling at the bottom of the stairwell.
•
Install a smoke alarm at the top of a
first-to-second floor stairwell.
•
Install a smoke alarm as close to the
center of the ceiling as possible. If this
is not practical, mount no closer than 4
inches from a wall or corner. Also, if
local codes allow wall mounting, you
may install smoke alarms on walls
between 4 and 12 inches from
ceiling/wall intersections.
•
Install a smoke alarm in each room that
is divided by a partial wall (either coming
down from the ceiling at least 24 inches,
or coming up from the floor).
•
Install smoke alarms on peaked, cathedral, or
gabled ceilings 3 feet from the highest point
(measured horizontally).
•
Install a smoke alarm in lived-in or
finished attics.
NOTE: For mobile homes built before 1978, install smoke alarms on
inside walls between 4 and 12 inches from the ceiling. (Older
mobile homes have little or no insulation in the ceiling.) This
is especially important if the ceiling is unusually hot or cold.
