• Locate at least one alarm on every floor level.
• Locate an alarm in every sleeping room.
• Locate an alarm in every room where electrical appliances are operated (i.e.
portable heaters or humidifiers).
• 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
barriers that may form at the ceiling. For more details, see MOBILE HOME
INSTALLATION.
• 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 ft (9.1 m) long.
