Kidde i12060 Smoke Alarm User Manual

Locate an alarm in every room where someone sleeps with the door closed.
The closed door may prevent an alarm not located in that room from waking
the sleeper.
Smoke, heat, and combustion products rise to the ceiling and spread horizon-
tally. Mounting the smoke alarm on the ceiling in the center of the room
places it closest to all points in the room. Ceiling mounting is preferred in
ordinary residential construction.
For mobile home installation, select locations carefully to avoid thermal barri-
ers that may form at the ceiling. For more details, see MOBILE HOME INSTAL-
LATION below.
When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm)
from the side wall (see FIGURE 1).
When mounting the alarm on the wall, use an inside wall with the top edge
of the alarm at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm)
below the ceiling (see FIGURE 1).
Put smoke alarms at both ends of a bedroom hallway or large room if the
hallway or room is more than 30 feet (9.1 m) long.
Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 3ft
(0.9m) of the highest point (measured horizontally). NFPA 72 states: “Smoke
alarms in rooms with ceiling slopes greater than 1 foot in 8 feet (.3m in 2.4
m) horizontally shall be located on the high side of the room.” NFPA 72
states: “A row of detectors shall be spaced and located within 3 ft (0.9m) of
the peak of the ceiling measured horizontally” (see FIGURE 3).
