Installation
6.1 Installation Location
Assess where needs to detect the cigarette smoke in the building. The places may include restrooms, staircase corridors of exit,
storage rooms, meeting rooms, and other places with fewer people.
Install the cigarette alarm near the smoking locations, such as the ceiling above the toilet water tank. The installation location
should be at least 10 cm away from the wall or corner. If the room has a steep or sloping ceiling, install the alarm at a
horizontal distance of 0.9 m from the highest point of the roof, as the Figure.

pitched roof
6.2 Inappropriate Installation Location
If the installation position is inappropriate, the alarm is prone to false alarms. To avoid false alarms, please do not install
alarms in the following locations.
Do not install in places where burning particles may appear or nearby, such as the kitchen with fewer windows or poor
ventilation, the garage which is prone to vehicle exhaust, fireplaces, or around burning heaters and other heaters. Burning
particles is a by-product of the burning objects, and it may cause the device to alarm.
In areas where is without air flow, smoke cannot enter the smoke collection box through the air flow caused by the ventilation
system to trigger the alarm. Otherwise, please avoid the area where the air flow will bring normal burning particles into the
device, such as the kitchen.
In a moist or hot and humid environment, or in an area within 3m from the bathroom, moisture in the air may enter the smoke
collection box and condense into water and dew during the cooling process that may cause false alarms.
In extremely cold or extremely hot environments including unheated buildings or outdoors, if the temperature exceeds the
limit of device operation temperature, the device will not operate normally.
In a dusty or dirty environment, dust may accumulate in the smoke collection box and cause the device to be overly sensitive.
In addition, dust can block the smoke inlet of the device and weaken the sense to smoke.
