Product details

Dimension

  • Product size: 110x110x32mm
  • Connection interface: 4-pin terminal

 

Initialization

When powered on,sensor indicator will turn off after flashing for 20S and will not detect moving signal during this time. After 20S,you can use our MH15 remote to adjust detection area、hold time and daylight sensor etc parameter.

 

Factory setting

Detection Area: 100%;  Hold Time: 1min;  Indicator light: open;  Daylight threshold:Disable

 

Detection Signal

The product detects human moving signals and below is a description of the moving signals:

  • Moving signal: detect the human significant moving (walking) in the detection area.

Wiring suggestions

 

Wiring layout suggestion:

  1. Our sensor is recommended layout in UPS circle to guarantee instant smart scene execution or electrical appliance operation
  2. LN terminal stands for AC input, L’N’ stands for AC output,please wiring correctly
  3. One sensor’s max loading capacity is 800w resistive loading and 400w inductive loading for one single load.if you want connect more load in one loop,we recommend to add an AC contactor in our output LN terminalto avoid momentary surge overload.
