M-204G Microwave Motion Sensor

Short Description:

1. Install the sensor. Place the device in the proper position, and remove the burrs completely when processing the cable hole. Open the mounting plate after opening the hole.


2. Connect the signal cable to the power terminal of the automatic dooc Green, white: signal output COM/NO Brown, yellow: power input AC / DC12V*24V.


3. Remove the outer cover and fix the sensor with screws.


4. Connect the terminal to the sensor.


5. Connect the power supply to the sensor, set the detection range and each function switch in sequenee.


6. Close the cover.

Detection range as below shown

NOTE: Please stand out of the detection range around 10S to ensure the sensor has enough time to finish the self- adjustme nt.


Sensitivity Adjustment

Detection Range MIN:0.5*0.4M MAX:4*2M Select differe nt detecti on range by adjusting sensitivity knob

Shape 18

Adjustment of detection direction

(Adjust Direction of front and back/Left and Right flexibly) Adjusting angle of Plain aerial to get different detection distance and range 30=15*2 range.

NOTE: The factory default is 45 degrees. All the parameters above are only for referenee, detection height is 2.2M. Detection range will be different because of the making material of door and ground, please adjust the sensitivity by the knob mentioned above. When adjusted to 60 degrees, the detection range is widest, which may cause self-serising and the door will always open and close.


Shape 26

Position should be fixed tightly to avoid vibrating

Shape 28

Sensors should not be placed behind the shield.

Shape 30

Moving object should be avoided

Shape 32

Fluorescent should be avoided

Shape 34

Do not touch directly, ESD Protect!on is necessary
