Kidde i9010 User Manual page 3

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 horizontally. 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 barriers that may form at the ceiling. For more details, see
MOBILE HOME INSTALLATION 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.
