NFPA Standard 72

In the United States and Canada, smoke detectors must be installed in accordance with National Fire Protection Association
(NFPA) Standard 72: National Fire Alarm and Signaling Code, which reads as follows:
"2‐1.1.1 Smoke alarms shall be installed outside of each separate sleeping area in the immediate vicinity of the bedrooms and
on each additional story of the family living unit including basements and excluding crawl spaces and unfinished attics. In new
construction, a smoke alarm shall be installed in each sleeping room.
2‐1.1.2 For family living units with one or more split levels (i.e., adjacent levels with less than one full story separation between
levels), a smoke alarm shall suffice for an adjacent lower level, including basements. (Exception: Where there is an intervening
door between one level and the adjacent lower level, a smoke alarm shall be installed on the lower level .)
• Ceiling mounted smoke alarms should be located in the center of the room or hall, or not less than 4 inches from any
wall . When the alarm is mounted on a wall, the top of the alarm should be 4 to 12 inches from the ceiling .
• Do not install smoke alarms where normal ambient temperatures are above 100°F (37.8°C), or below 40°F (4°C). Also, do
not locate alarm in front of air conditioners, heating registers, or other locations where normal air circulation will keep
smoke from entering the detector .
A‐2.5.2.1 Smoke Detection - 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 residential user 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 or false alarms".
NOTE: Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for
the purpose .
