Ceiling installation of a microwave sensor switch body microwave sensor switch, the microwave sensor switch for active sensors, sensors, launch the high-frequency electromagnetic waves (5.8GHz) and receive their net change within this sensor to detect the echo is even true tiny mobile detection range did not, then the microprocessor trigger "point of light instruction signal through the doors, glass and thin walls are likely to be detected, 

 Note: The person or object toward the detection results when the sensor moves! 

 Note: this high-frequency output of the sensor is less than 10mW, just phone or microwave transmission power of the 100 one. 

 Ceiling microwave sensor switch installation steps: 



 A counterclockwise rotation of the top cover and remove it (see FIG. 1) Open the two screws fixed in the cover (see FIG.2); 

 2, the base of the top drill mark on the wall to do, pay attention to the lead on the wall; 

 3, drilling, plastic expansion of the body to knock a hole; 

 4, the power cord through the base; 

 5, using the mounting screws to secure the base in the selected installation location (see FIG.3) 

 Identified according to the wiring of the power cord and load cord to the terminal; 

 7, close the cover, tighten the screws (see FIG.3); and then adjust the knob to set; 

 8, clockwise tighten the cover (see FIG.3).
