Fig. 3 – Dead-air areas
• In damp or very humid areas, or within 3 m of bathrooms with showers. Humid
air contains moisture that 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 alarm, the
alarm 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 be overly sensitive. Additionally, dust or dirt can block
openings to the sensing chamber and limit the alarm from sensing smoke.
• Near fresh air vents or high draft areas like air conditioners, heaters or fans,
fresh air vents and drafts. Such environments can drive smoke away from
alarms.
• In dead air spaces, which are often at the top of a peaked roof or in the apex
of ceilings and walls. Dead air may prevent smoke from reaching an alarm. See
Fig. 4 for the recommended location.
