10. NFPA Required Protection
The National Fire Protection Association’s Standard 72 provides the following information:
Smoke Detection - Where required by applicable laws, codes, or standards for a specific type of occupancy, approved single- and
(1)In all sleeping rooms and guest rooms
(2)Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft) of any door to a sleeping room, the distance measured along a path of travel
(3)On every level of a dwelling unit, including basements
(4)On every level of a residential board and care occupancy (small facility), including basements and excluding crawl spaces and unfinished attics
(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)
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, the use of additional smoke alarms for those areas for increased pro- tection is recommended. The additional areas include the basement, bed- rooms, 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, because these locations occasionally experience conditions that can result in improper operation.
11.CAUTION (AS REQUIRED BY THE CALIFORNIA STATE FIRE MARSHAL)
Ionization type smoke alarms use a very small amount of a radioac- tive element in the sensing chamber to enable detection of visible and invisible combustion products. The radioactive element is safely contained in the chamber and requires no adjustments or mainte- nance. This smoke alarm meets or exceeds all government stan- dards. It is manufactured and distributed under license from the U.S. Nuclear Regulatory Commission.
