AREAS.
Where to Locate the Required Smoke Alarms. The major threat from fire in a dwelling unit
occurs at night when everyone is asleep. Persons in sleeping areas can be threatened by fires
in the remainder of the unit; therefore, smoke alarms are best located in each bedroom and
between the bedroom areas and the rest of the unit as shown in FIGURE 2.

IMPORTANT CONSIDERATION
NFPA 72, 2013 Edition, Chapter 29, Section 29.8.1.4(5)(b) states: “Smoke alarms
installed in one- and two-family dwellings shall not remain in service longer than 10
years from the date of manufacture.” Smoke alarms should be replaced for the
following reasons:
w Dust, dirt, and other environmental contaminants can affect your smoke alarm over a
prolonged period.
w Fast changing industry consensus standards and codes on all smoke alarms make it
advisable to periodically upgrade your device to maximize life safety.
w Assurance that your smoke alarm needs are kept abreast with the constantly improving
electronic technology.
w Smoke alarms are recognized as one of the lowest cost ways to protect dwelling
inhabitants against the danger of fire(s). It makes good common sense to periodically
replace and update your smoke alarm that contributes so much to life safety.
MOUNTING LOCATION
w Ceiling location (7139CS only) - smoke alarm should be mounted as close as possible to
the center of a hallway or room.
w Wall location-locate the top of the smoke alarm not more than 12 inches from the ceiling
and must be within 16 feet of pillow. Observe smoke alarm for proper top/bottom
orientation (test knob is near bottom of unit).
w Smoke alarm with visual signal is to be mounted per NFPA 72 Annex A. 29.8.3. Ceiling
location - smoke alarm should be mounted as close as possible to the center of a hallway
or room. If this is not possible, the edge of the unit must be within 16 feet of pillow. Wall
location-locate the top of the smoke alarm not more than 12 inches from the ceiling and
must be within 16 feet of pillow. Observe smoke alarm for proper top/bottom orientation
(test knob is near bottom of unit).
5) In the living area(s) of a guest suite
6) In the living area(s) of a residential board and care occupancy (small facility)
29.5.1.2 Where the area addressed in 29.5.1.1(2) is separated from the adjacent living areas
by a door, a smoke alarm shall be installed in the area between the door and the sleeping
room, and additional alarms shall be installed on the living area side of the door as specified
by 29.5.1.1 and 29.5.1.3.
29.5.1.3 In addition to the requirements of 29.5.1.1(1) through 29.5.1.1(3), where the interior
floor area for a given level of a dwelling unit, excluding garage areas, is greater than 93m
2
(1000ft
2
), smoke alarms shall be installed per 29.5.1.3.1 and 29.5.1.3.2.
29.5.1.3.1 All points on the ceiling shall have a smoke alarm within a distance of 9.1m (30ft)
travel distance or shall have an equivalent of one smoke alarm per 46m
2
(500ft
2
) is
evaluated by dividing the total interior square footage of floor area per level by 46m
2
(500ft
2
).
29.5.1.3.2 Where dwelling units include great rooms or vaulted/cathedral ceilings extending
over multiple floors, smoke alarms located on the upper floor that are intended to protect the
aforementioned area shall be permitted to be considered as part of the lower floor(s)
protection scheme used to meet the requirements of 29.5.1.3.1.
The installation of additional alarms of either the smoke, heat or CO type should result in
a higher degree of protection. Adding alarms to rooms that are normally closed off from the
required alarms increases the escape time because the fire does not need to build to the
higher level necessary to force smoke out of the closed room to the required alarms. As a
consequence, it is recommended that the householder consider the installation of additional
fire protection devices. However, it should be understood that NFPA 72 does not require
additional smoke alarms over and above those called for in FIGURES 1, 2, 3 and 4 where
required smoke alarms are shown.
FIGURE 2: A SMOKE ALARM MUST BE LOCATED BETWEEN THE SLEEPING AREA AND
THE REST OF THE DWELLING UNIT AS WELL AS IN EACH BEDROOM.
In dwelling units with more than one bedroom area or with bedrooms on more than one
floor, more than one smoke alarm is required, as shown in FIGURE 3.
FIGURE 3
Figure 3: IN DWELLING UNITS WITH MORE THAN ONE SLEEPING AREA, A SMOKE
ALARM MUST BE PROVIDED TO PROTECT EACH SLEEPING AREA IN ADDITION TO
SMOKE ALARMS REQUIRED IN BEDROOMS.
In addition to smoke alarms outside of the sleeping areas and in each bedroom, NFPA 72
requires the installation of a smoke alarm on each additional level of the dwelling unit,
including the basement. These installations are shown in FIGURE 4. The living area smoke
alarm should be installed in the living room or near the stairway to the upper level, or in both
locations. The basement smoke alarm should be installed in close proximity to the stairway
leading to the floor above. Where installed on an open-joisted ceiling, the smoke alarm
should be placed on the bottom of the joists. The smoke alarm should be positioned relative
to the stairway so as to intercept smoke coming from a fire in the basement before the
smoke enters the stairway.

GABLED, OR PEAKED CEILINGS.
The placement of the smoke alarm is critical if maximum speed of fire detection is
desired. Thus, a logical location for a smoke alarm is the center of the ceiling. At this
location, the device is closest to all areas of the room.
