Product details

Appearance feature

  • Size:φ105x85mm
  • Terminal:4 hole press terminal

 

Initialization

For the initial 20S interval once our motion sensor is powered,our motion sensor’s sensing function is disabled and can’t response to human motion.After that,our motion sensor can work normally and its indication light can be turned on or off by our MH10 remote control.

 

Factory setting

Detection sensitivity: 100%,   Hold time: 1 Minute

 

Motion signal description

Our 24GHz millimeter motion sensor can precisely detect human movement motion and human presence signal to output presence and absence status,and below is human movement motion and human presence signal description

  • Movement motionIt refers to human big movement behaviour,such as walking within our detection area
  • Human presenceIt refers to human vital signs,such as breathing and finger tapping within our detection

Remark: Only when our motion sensor is triggered by movement motion firstly,so that it can detect human presence

Wiring suggestions

 

Installation suggestion

Embedded mounting installation

  1. Cut out a φ70~75mmhole
  2. Carefully loose the screw and cable clip after open the rear cover
  3. Securely wire cable into the terminal
  4. Firmly screw down the cable clip and cover it well
  5. Put the spring clip into the hole and fasten itwell
