Risco RWX34S Instructions D'installation page 4

If ceiling mounting is not possible and 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
and heat detector installed in each separate sleeping
area (in the vicinity, but outside of the bedrooms),
and (2) Heat or smoke and heat 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 and heat 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 and heat detectors for increased
protection for those areas separated by a door from
the areas protected by the required smoke and heat
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 and heat detectors.
