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
