F i g u re A.11.8.3 Example of Proper Mounting for Detectors
The situation described pre v i o u s l y
for insinuated or poorly insulated ceilings can
also exist, to a lesser extent, in the case of
outside walls. The recommendation is to
place the smoke alarm or smoke detector on
a sidewall. However, where the sidewall is an
exterior wall with little or no insulation, an inte-
rior wall should be selected. It should be re c-
ognized that the condition of inadequately
insulated ceilings and walls can exist in
multifamily housing (apartments), single-family housing, and mobile homes.
In those dwelling units employing radiant heating in the ceiling, the
wall location is the recommended location. Radiant heating in the ceiling can
c reate a hot-air, boundary layer along the ceiling surface, which can seriously
restrict the movement of smoke and heat to a ceiling-mounted detector.
This equipment should be installed in accordance with the National Fire
Protection Association's Standard 72, NFPA, Batterymarch Park, Quincy,
MA 02269.
THIS STANDARD MEANS YOU SHOULD INSTALL AND USE A SMOKE
ALARM IN EVERY ROOM AND AREA OF YOUR HOUSEHOLD OR
BUILDING FOR BEST PROTECTION.
For best protection, install a smoke alarm in EVERY room. In addition,
we recommend that all smoke alarms be interconnected.
In addition, the California State Fire Marshal states: "Early warning fire
detection is best achieved by the installation of fire detection equipment
in all rooms and areas of the household as follows: A heat detector
installed in each separate sleeping area (in the vicinity, but outside the
bedrooms) and heat or smoke alarms in the living rooms, dining rooms,
bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and
storage rooms, basements and attached garages."

HEAT ALARM LOCATIONS
• Install a heat alarm as close to the center of the ceiling as possible. If this
is not practical, mount no closer than 10 cm (4 in) from a wall or corn e r.
• If ceiling mounting is not practical or the mount-
ing surface becomes considerably warmer or
cooler than the room (such as a poorly insulated
ceiling, below an unfinished attic or an exterior
wall) and if local codes allow, install heat alarm s
on walls, between 10 and 30 cm (4 and 12 inch-
es) from ceiling/wall intersections.
