Installation Precautions of 12 Volt PIR Sensor Switch
The 12Volt PIR Sensor Switch works by detecting the presence or absence of human infrared rays, 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 noted when installing the human body sensor switch:
1. Do not operate with power on during installation and then power on after installation.
2. Do not use it in the over power range.
3. When installing the human body sensor switch, it should be far away from places sensitive to air temperature changes such as heating, air conditioning, refrigerators, and stoves.
