Recommended Locations For Smoke Detectors - Interlogix SDX-135Z User Manual

7. recommended Locations for Smoke Detectors

• Locate detectors in all sleeping areas. Try to monitor the exit path as the bedrooms are usually farthest
from the exit. If more than one sleeping area exists, locate additional detectors in each sleeping area.
• Locate additional detectors to monitor any stairway as stairways act like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate a detector in every room where electrical appliances are operated (i.e. portable heaters or hu-
midifiers), as long as the room is environmentally controlled within the temperature and humidity ranges
as defined in the "Specifications" table.
• Locate a detector in every room where someone sleeps with the door closed. The closed door may
prevent a detector not located in that room from waking the sleeper.
• Smoke, heat, and combustion products rise to the ceiling and spread horizontally. Mounting the smoke
detector on the ceiling in the center of the room places it closest to all points in the room. Ceiling mount-
ing is preferred in ordinary residential construction.
• When mounting a detector on the ceiling, locate it at a minimum of 4" (10 cm) from the side wall.
• When mounting the detector 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.
• Put smoke detectors at both ends of a bedroom hallway or large room if the hallway or room is more
than 30 feet (9.1m) long.
• Install smoke detectors on sloped, peaked or cathedral ceilings at or within 3ft (0.9m) of the highest
point (measured horizontally).(0.9m) of the highest point (measured horizontally).
This equipment should be installed in accordance with the National Fire Protection Association's 72 (Na-
tional Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
