Product Description

Detection Range

This figure indicates the maximum distance at the highest mounting height with 100% sensitivity.

Typical installation height 2.5-6m.

Mechanical structure

With six DIP switch poles to set all parameters

With four poles to easily connect with LED driver and power supply

With two installation hole, easily fixed to the lighting fixture for end user.

Detection area

In this area,movement will be detected and able to trigger the sensor.

100% detection area is also known as the strong sensitivity.

Hold Time

The period of light keeping 100% brightness after

moving abjects leave the detection area.

Daylight threshold

Definition of the ambient brightness;only when the

ambient brightness is lower than the preset specific

lux amount,the sensor will work;when it's preset as

"disable",the sensor works everytime it detects motion

regardless the ambient brightness.

Application Demo

1. Automatically ON/OFF function:

Light on when detect movement and off after people leave at night. Applications: Corridor, Staircase.

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 stand-by period.
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.

Installation Method:

Installation Precautions:

1. Microwave sensor can be installed in any lamp except the one with full metal shell.

2. The detected surface can not be shielded by metal objects.

3. Make sure the microwave module is completely exposed outside.

4. The detection surface of the snesor module shall be installed facing the detection area.

5. Should be kept away from the driver to avoid interference generation and lamp flashing.

6. Wiring must be strictly in accordance with the wiring diagram to avoid short circuit.

Appliction Environment:

1. Suitable for indoor installation to aviod false triggering due to external factors such as rain,wind or tree swing.

2. Shall not be installed in the place with all four metal shelters and small space(such as galvanized-iron roof).

3. Shall not be installation,so as to aviod false trigger caused by the lamp itself shaking.

4. Shall not be installation next to large operating machines such as ventilator/ceiling fan to aviod false triggering caused by machine vibration.
