KNX occupancy detector designed for high-bay warehouses, with integrated KNX bus connector
External telescopic light sensor for a mounting height between 5 and 16 m (mechanically adjustable) for measuring the light according to the application.
Mixed light measurement with internal and external light sensor
1 x light output (for regulating or switching), 1 x slave output, 3 x HVAC outputs (separately programmable)
Intelligent semi-automatic mode, occupancy-independent regulating mode (photoelectric switch), full automatic mode
Two logic modules
Individual adaption of detection sensitivity for each PIR sensor
Direction of movement can be identified
Various locking functions
Status LEDs can be activated / deactivated
Programming button (phys. address) can be operated via remote control
Regulation/switching of three light groups via offset (external influence possible)
Short presence, self-adjusting follow-up time, corridor function
Recall of light scenes
Temperature sensor
HVAC mode (0=automatic, 1=comfort, 2=stand-by, 3=economy, 4=antifreeze/heat protection)
5 button remote control, programmable at choice (accessory)
Occupancy simulation
PIR sensors can be deactivated individually
Detection area can be extended thanks to master-slave-mode
Extensive optimization options for light measurement
Measured light value is communicated to the bus
IR remote control-capable via IR remote control (optionally)
PIN code
Manual influence via external KNX push buttons possible
Function control (heartbeat, cyclical sending)
Forced switch-off
Intelligent central-off function
Premonition of switch-off
Behaviour upon bus voltage return definable at choice
Variable safety pause after switching off the lights
Settings ex ETS 4 for integration in KNX systems
The product database for import into the ETS database can be downloaded from the B.E.G. homepage.
Adaption of dimming curve
Determination of the reflection factor, e.g. on a desk, with the optional BLE-IR-Adapter
Burn-in function for fluorescent lamps selectable from 1h till 100h
Soft-start
Blinds
There are markings to ensure correct alignment during installation
When used in high-bay warehouses, care should be taken that, in the cross-aisles of the warehouse, detectors are installed that can detect movement only in the desired aisle locations, by using blinds or other technical arrangements.
