wall mounting is permitted by your local
and state codes, put wall-mounted
detectors between 4 and 6 inches (10 ~
15 cm) from the ceiling, also see
Figure 4.
♦ If some of your rooms have sloped,
peaked, or gabled ceilings, try to mount
detectors 3 feet (0.9 meter) measured
horizontally from the highest point of the
ceiling as shown in Figure 5.
CAUTION:
(As required by the California State Fire Marshall)
“ Early warning fire detection is best achieved by the
installation of fire detection equipment in all rooms
and areas of the household as follows: (1) A smoke
detector installed in each separate sleeping area (in
the vicinity, but outside of the bedrooms), and (2)
Heat or smoke detectors in the living rooms, dining
rooms, bedrooms, kitchens, hallways, attics, furnace
rooms, closets, utility and, storage rooms, basements
and attached garages.”
For your information, NFPA Standard 74, Section 2-4
reads as follows:
“2-4.1.1 Smoke detectors 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.
The provisions of 2-4.1.1 represent the minimum
number of detectors required by this standard. It is
recommended that the householder consider the use
of additional smoke detectors for increased
protection for those areas separated by a door from
the areas protected by the required smoke detectors
under 2-4.1.1 above. The recommended additional
areas are living room, dining room, bedroom(s),
kitchen, attic (finished or unfinished), furnace rooms,
utility room, basement, integral or attached garage,
and hallways not included in 2-4.1.1 above. However,
the use of additional detectors remains the option of
the householder.” We recommend complete
coverage and use of additional smoke detectors.
