4. Recommended Locations For Alarms
• Check specific State legislation in your area to ensure smoke alarms are correctly
located according to local laws. Each State or Territory may differ in building codes and
regulations. PSA Products can only recommend the locations.
• Locate an alarm for each separate sleeping area in the immediate vicinity of the
bedrooms. Try to monitor the exit path as the bedrooms are usually farthest from an exit.
If more than one sleeping area exist, locate additional alarms in each sleeping area in the
immediate vicinity.
• Locate additional alarms to MONITOR any stairway because stairways act like chimneys
for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every room where a smoker sleeps.
• 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 other combustion products rise to the ceiling and spread horizontally.
Mounting the 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..
• When mounting alarms on the ceiling locate it at least 300mm away from the side wall
and 300mm away from any corner. (see diagram).
• When mounting alarms on a wall, use the inside wall. The recommended position is
between 300mm and 500mm off the ceiling. (see diagram).
NOTE: The performance of smoke alarms mounted on walls is unpredictable
and this mounting position is not recommended when ceiling mounting can be
implemented.
