Locations to avoid
Do not locate smoke alarms:
• In turbulent streams of air such as near fens, heaters, doors and windows, etc. These
can draw smoke away from the alarm.
• In high humidity areas such as bathrooms and shower rooms as high humidity can
trigger the alarm, or where temperature exceeds 40°C or below 0°C.
• At the apex of an "A" frame ceiling. "Dead air" at the top may prevent smoke from
reaching the alarm in time to provide early warming.
• Less than 300mm (12 inches) from the wall when mounted on the ceiling.
• In insect-infested areas, tiny insects may affect performance.
• In kitchens, boiler rooms, laundry rooms, garages. Combustion particles from cooking or
car exhausts and dust and moisture could trigger the alarm.
• In very dusty or dirty areas, dirt and dust can build up and impair performance.
• Within 300mm (12 inches) of light fittings or room corners.
• In locations which would make routine testing or maintenance hazardous (eg,over a
stairwell).
• On poorly insulated walls or ceilings.
• Near objects such as ceiling decorations which might impede the path of smoke to the
alarm.
• Within 1500mm (5 feet) of fluorescent light fittings.
