Product Information


  • Bidirectional occupancy detector with integrated DALI application controller for an energy-efficient and biologically effective light control (Human Centric Lifghting)
  • Integrated DALI power supply and 3 push-button inputs
  • Preset and freely adjustable HCL curves (12 anchor points per 24h)
  • Adjustable communication mode "Broadcast" (1 light zone, without addressing) or "Multicast" (several light zones, HVAC, with addressing)
  • Dim-2-Warm: brightness and colour temperature can be infinitely adjusted simultaneously with a long keystroke
  • Calling up lighting scenes using accessory
  • Mixed light measurement with internal and external light sensor
  • External light sensor can be swivelled by 45
  • 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 range can be extended with up to 8 B.E.G. BMS multisensors
  • Up to 64 DT8 driver luminaires (Colour Type Tc), doubling the DALI output current with accessory may be necessary
  • Complete range of functions can only be activated using the BLE-IR-Adapter and a compatible Smartphone or Tablet (Android, iOS).
  • 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
  • An outdoor colour temperature light sensor, available as an accessory, can be used to measure / transmit the current daylight value
  • Lighting zone A for main lighting with segmented, daylight-dependent regulation in offset mode via 3 DALI groups
  • Lighting zone B for desk or accent lighting via separate DALI group or via integrated relay
  • Lighting zone B - Output type adjustable to switching output (factory setting) or regulation output (same as group 1)
  • Manual switching or dimming via conventional pushbuttons
  • Colour temperature can be adjusted separately and continuously via separate push-button input
  • Adjustable dynamics (minimum and maximum values) for brightness and colour temperature
  • Status LEDs can be activated / deactivated
  • PIN code
  • Orientation light function
  • Number of DALI participants can be determined quickly and reliably via the B.E.G. Online DALI Line Planner
  • Avoidance of standby losses of the lighting system in accordance with EnEV DIN V 18599-4
