The detector should be installed in a place where gas is easy to leak, and the specific location should be determined according to the specific gravity of the detected gas relative to air.
When the specific gravity of the gas to be detected is greater than that of air, the detector should be installed at a distance (30-60) cm from the ground, with the sensor pointing downward.

Wireless Infrared Human Body Induction KD-702LA

When the specific gravity of the gas to be detected is lower than that of air, the detector should be installed at a distance (30-60) cm from the ceiling, with the sensor facing down.
In order to use the detector correctly and prevent the occurrence of detector failure, please do not install it in the following locations:
Places directly affected by steam and oil fume;
Places with large air flow such as air inlets, ventilation fans, and room doors;
Places with a lot of water vapor and water droplets (relative humidity: ≥90%RH);
Where the temperature is below -40°C or above 55°C;
Where there is a strong electromagnetic field.
