The presence detector only reports movement when both its sensing parts are triggered. High sensitivity detects also slight movements and it is hence suitable not just for security applications but also for lighting control.


  • Quad element PIR sensor
  • X‑band high frequency doppler sensor (HFD)
  • 24VDC power supply, the same as for other system modules
  • 4 levels of HFD sensitivity adjustable
  • Two sensor operation LED indicators
  • It switches its output when both PIR and HFD sensors detect movement
