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 alarm should
be placed on the bottom of the joists. The alarm
should be positioned relative to the stairway to
intercept smoke coming from a fire in the basement
before the smoke enters the stairway.
Where to Locate the Required Smoke Alarms in
Existing Construction
All of the smoke alarms specified for existing con-
struction are required and, in addition, a smoke alarm
is required in each bedroom.
Are More Smoke Alarms Desirable?
The required number of smoke alarms might not
provide reliable early warning protection for those
areas separated by a door from the areas protected
by the required smoke alarms. For this reason, it is
recommended that the (designer/installer) consider
the use of additional smoke alarms for those areas for
increased protection. The additional areas include the
basement, bedrooms, dining room, furnace room,
utility room, and hallways not protected by the
required smoke alarms. The installation of smoke
alarms in kitchens, attics (finished or unfinished), or
garages is not normally recommended, as these
locations occasionally experience conditions that can
result in improper operation.

In addition to NFPA 72, use the following location
guidelines to optimize performance and reduce the
chance of false alarms.
Locate ceiling mounted smoke detectors in the center
of a room or hallway at least 4 inches from any walls
or partitions.
Locate wall mounted smoke detectors so the top of
the alarm is 4 to 12 inches below the ceiling.
When more than one detector is required, spacing of
30 feet may be used as a guide on smooth ceilings.
Other spacing may be used depending on ceiling
height, high air movement, and other conditions or
response requirements.
Locate in a suitable environment:
-Temperature between 32°F (0°C) and 100°F (38°C)
-Humidity between 0 and 95% non-condensing
Locate away from air conditioners, heating registers
and any other ventilating source that may interfere
with smoke entering the detector. Locate away from
kitchens, wood stoves, garages, furnaces and
bathrooms.
Mount smoke detectors on a firm permanent surface,
typically a stud or metal runner.
