2. Installation
Recommended Locations
•
Locate the first alarm in the immediate area of the sleeping rooms.
Try to monitor the exit path, as the sleeping rooms are usually
farthest from the exit. If more than one sleeping area exists, locate
additional alarms in each sleeping area (Image 1A).
•
Locate additional alarms to monitor any stairway as stairways act
like chimneys for smoke and heat.
•
Locate at least one alarm on every floor level (Image 1B).
•
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 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 Homes.
•
When mounting an alarm on the ceiling, locate it at a minimum of
10 cm (4") from the side wall (Image 2A).
•
When mounting the alarm on the wall, use an inside wall with
the top edge of the alarm at a minimum of 10 cm (4") and a
maximum of 30.5 cm (12") below the ceiling (Image 2A).
•
Put smoke alarms at both ends of a hallway or large room if the
hallway or room is more than 9.1 m (30 ft) long. For large rooms,
one smoke alarm is recommended for every 500 square feet of
floor space.
•
Install smoke alarms on sloped, peaked or cathedral ceilings
following the mounting guidelines outlined in Image 2B and 2C.
Smoke alarms in rooms with ceiling slopes greater than 0.3 m in
2.4 m (1 foot in 8 feet) horizontally shall be located on the high
side of the room (Image 2B and 2C).
