Product Information

  • Bidirectional occupancy detector with integrated DALI controller for an energy-efficient and biologically effective light control (Human Centric Lifghting)
  • Very sensitive occupancy detector with the ability to address up to 64 DALI-DT8 Tunable White luminaires approved by B.E.G. and to control them in groups
  • The integrated real time clock regulates automatically the colour temperature and the brightness level in such a way that the human circadian rhythm is supported
  • 3 light zones:
    A for the main light with segmented HCL control via 3 groups and offset control,
    B for desk or accentuated illumination via a separate DALI group,
    C for desk or accentuated illumination via integrated relay
  • Pure Colour: An outdoor colour temperature light sensor, available as an accessory, can be used to measure / transmit the current daylight value.
  • Manual switching or dimming via conventional pushbuttons
  • Powerful switching relay for different operating modes, e.g. Cut-off function for DALI ballasts, HVAC, blackboard illumination.
  • Quick commissioning and maintenance processes via Smartphone/Tablet App (Android, iOS) - No PC-Tool required
  • Detection area can be extended with up to four Slave devices of type PD4-S-DAA4G
  • Complete range of functions can only be activated using the B.E.G. IR Adapter or the BLE-IR-Adapter and a compatible Smartphone or Tablet (Android, iOS).
  • Avoidance of standby losses of the lighting system in accordance with EnEV DIN V 18599-4
