Install it 30 cm below the ceiling of the room to be detected, or on the ceiling. The installation location should not be too close to the gas stove or hood. Avoid oil fumes directly entering the alarm, otherwise it will affect the sensitivity of the alarm. Household carbon monoxide alarms are used for gas and CO leakage detection and can be installed in kitchens, bathrooms and other places. During the heating period in winter, the doors and windows are usually closed tightly, and the gas (carbon monoxide gas) in the air is inconvenient to circulate, which increases unsafe factors. The use of household carbon monoxide alarms (gas alarms) can effectively prevent the occurrence of danger.
