Where Not to Install Your Alarm
Nuisance alarms occur when alarms are installed where they will not work properly.
To avoid nuisance alarms, do not install alarms in the following situations.
• In or near areas where combustion particles are present, such as kitchens with
few windows or poor ventilation, garages where there may be vehicle exhaust,
near furnaces, combustion heaters, and space heaters. Combustion particles are
the by-products of something that is burning, which the alarm may detect. As a
guide, aim to avoid installing an alarm within 6 m of kitchens where combustion
particles are normally present. If a 6 m distance is not possible (e.g. in a mobile
home), try to install the alarm as far away from the combustion particles as
possible, preferably on the wall. Ensure the area is well ventilated.
• In dead air ceiling or wall spaces, which are often at the top of a peaked roof
or in apex of ceilings and walls. Dead air may prevent smoke from reaching the
alarm. See Fig. 3 for the recommended installation location in such situations.
• In other dead-air areas, where ventilation systems cause airflow that would not
pass through the smoke sensing chamber. Also avoid airflow from areas where
normal combustion articles are expected, such as kitchens. Refer to Fig. 4,
which indicates the correct and incorrect alarm locations.

• In damp or very humid areas, or within 3 m of bathrooms with showers.
Moisture in humid air can enter the sensing chamber then condense into
droplets upon cooling, which can cause nuisance alarms.
• In very cold or very hot areas, including unheated buildings or outdoor rooms.
If the temperature rises above or falls below the operating range of the alarm, it
may not function properly. The temperature range for your alarm is
(0 ~ 55) °C.
• In very dusty or dirty areas. Dirt and dust can build up on the smoke sensing
chamber, causing it to become overly sensitive. Additionally, dust or dirt can
block openings to the sensing chamber and prevent the alarm from sensing
smoke.
