Compact light sensor module for DALI and DALI-2 systems.
2 operating modes are supported: constant light control or light control via 4 threshold values.
The operating mode can easily be changed via scene calls or external DALI commands. The constant light control automatically regulates the light level of individual luminaires or luminaire groups to a user-defined light value. Blinds and roller blinds can be automated via user-defined light thresholds.

The module can either be used to directly control the DALI system (application controller) or simply to gather measurements for a building management system (instance mode). Multiple sensors can be used in one system.
The measured values can be read out via the DALI line.
The device is powered directly by the DALI bus.

DALI-2 LS is available in three different housings: for direct mounting on cavity walls or installation boxes (standard), for suspended ceilings (with spring), or for surface mounting (with backbox). Available housing colours are pure white RAL 9010 and traffic white RAL 9016 (-W16).
Factory setting: Application Controller – Master Mode, constant light control, target value 500lx, effective range: broadcast
