*When set to Disable gear, the sensor will turn on the light as long as the motion of the object is detected, regardless of whether the illumination is adequate or not.

9. Override Function


Quick switch ON/OFF 3 times within 2sec to override sensor function. Lights will switch on all the time. Power off and on again to recover sensor function.


10. Initialization


After power on, the sensor automatically turns on light at 100% brightness. After 10sec, it turns off the light. During the initialization, the sensor is not able to detect movement.


11. Factory settings


Detection Area: 100%, Hold Time: 5S, Daylight Sensor: Disable


12. Use Caution


1. Be sure to cut off the power supply before installing or adjusting the setting of the dial switch.

2. The microwave cannot pass through the metal, make sure there are no metal above the sensor.

3. It has to be at least 3.5mm away from metal around the microwave antenna. It is not allowed to place antenna and metal on the same horizontal.

1. Automatically ON/OFF function:


Light on when detect movement and off after people leave at night. Applications: Corridor, Staircase.
The daylight threshold is set to "2lux,10lux,50lux,Disable"


With sufficient daylight, With insufficient daylight, After the last detection and
even when motion detected, when motion detected, light ON. the present hold time
light remains OFF. elapsed, light OFF.


2. No daylight function

The daylight threshold is set to "Disable".
Light on when detect movement, After people leave, Light off after hold time.
Applications: Dim places such as Basement Parking, Underpass.


When motion is detected, After people leave the detection After the last detection and
the sensor will switch on the area, light remains 100% the present hold time
light to 100% brighteness. brightness within hold time. elapsed, light OFF.
