Wireless Supervisor Photoelectric Smoke Detector 5
SELECTING A LOCATION
Smoke detectors should be installed in accordance with the NFPA Standard 74
(National Fire Protection Association, Batterymarch Park, Quincy, MA 02169). For
complete coverage in residential units, smoke detectors should be installed in all
rooms, halls, storage areas, basements, and attics in each family living unit.
Minimum coverage is one detector on each floor and one in each sleeping area and
attics in each family living unit. Minimum coverage is one detector on each floor and
one in each sleeping area.
♦ Install a smoke detector in the hallway
outside every separate bedroom area,
as shown in Figure 1. Two detectors are
required in homes with two bedroom
areas, as shown in Figure 2.
♦ Install a smoke detector on every floor
of a multi-floor home or apartment, as
shown in Figure 3.
♦ Install a minimum of two detectors in
any household.
♦ Install a smoke detector inside every
bedroom.
♦ Install smoke detectors at both ends of
a bedroom hallway if the hallway is
more than 40 feet (12 meters) long.
♦ Install a smoke detector inside every
room where one sleeps with the door
partly or completely closed, since
smoke could be blocked by the closed
door and a hallway alarm may not wake
up the sleeper if the door is closed.
♦ 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 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
