Install basement detectors at the
bottom of the basement stairwell.
Install second-floor detectors at
the top of the first-to-second floor
stairwell.
Be sure no door or other
obstruction blocks the path of
smoke to the detector.
Install additional detectors in your
living room, dining room, family
room, attic, utility and storage
rooms.
Install smoke and heat detectors
as close to the center of the
ceiling as possible. If this is not
practical, put the detector on the
ceiling, no closer than 4 inches
(10 cm) from any wall or corner,
as shown in Figure 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.
