in a DALI system.
Functioning as a presence detector, the unit can turn the lights on when a room is occupied, and off when unoccupied.
It is fully compatible with Helvar's lighting system design and control software: Designer, and Toolbox.

Sensitivity, Time-Outs, Identify
Sensitivity
Adjust the sensitivity using Designer or Toolbox – Helvar's lighting system design and control software.
The factory default setting is 9 (maximum).
Note: On maximum sensitivity, the detector unit is extremely sensitive to movement and may detect through
glass, thin walls or partitions. If this causes a problem, reduce its sensitivity.
The temperature difference between the detection target and the background must be at least 4 °C.
Adjusting On, Exit and Transition Time-Outs
The default time-outs for On, Exit and Transition can be altered using Designer or Toolbox.
Identify: Check Connection to DALI Network
To make sure that the sensor is correctly connected to the DALI network, use the Identify function in Designer or
Toolbox. The sensor's status LED flashes repeatedly until Identify is cancelled.
