The sensor switch works by detecting the presence or absence of infrared rays on the human body, and is generally installed indoors. The false alarm rate of the human body sensor switch has a great relationship with the installation position and method. The following points should be paid attention to when installing the human body sensor switch:
1. Do not operate with power during installation, and power on after installation.
2. Do not use it beyond the power range.
3. The top-mounted human body induction switch should not be too high from the ground, preferably between 2.4-3.1 meters. The wall-mounted human body sensor switch can be installed in the original switch position and replaced directly.
4. When installing the human body sensor switch, it should be far away from the place where the air temperature changes such as heating, air conditioner, refrigerator, stove and so on.
5. There shall be no screens, furniture, large bonsai or other partitions within the detection range of the sensor switch.
6. Do not switch the switch directly to the window, to prevent the disturbance of hot air outside the window and the movement of people from causing false alarms.
7. Do not install the switch in places with strong air currents, such as doorways and air ducts.
