Recommended Locations For Smoke Alarms - Kidde P4010ACS-WCA User Manual

7. Recommended Locations for Smoke Alarms

•
Locate smoke alarms 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 alarms in each sleeping area.
•
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.
•
Locate an alarm in every bedroom.
•
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.

room." NFPA 72 states: "A row of detectors shall be
spaced and located within 0.9 m (3 ft) of the peak of
