Nfpa Standard 72 - 2gig Technologies Go!Control Panel Installation & Programming Manual

NFPA STANDARD 72
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.
