Installation instructions: Combined Sensor DALI LS/PD ADVANCED
1. Function
overview
The radio-control combined sensor maximises energy savings by combining presence-controlled
lighting with daylight-dependent control.
It comprises a passive infrared sensor (PIR) which reacts to the movement of heat and therefore to
the presence of people, and also a light-sensitive resistor that measures the luminance in a defined
detection area. The sensor forwards this dual information (brightness and presence) to the DALI
ADVANCED central unit. The data is evaluated in the central unit and the lighting system controlled
accordingly.
When movement is detected, the combined sensor switches the luminaires of the relevant group on
and automatically starts controlling the lighting level. Lighting control remains active as long as the
sensor detects movement. When movement is no longer detected, the lighting system is switched off
after a user-definable delay. The lighting system is also switched off if a brightness threshold is
exceeded.
The combined sensor consists of the following:
Sensor window with LED below it
Decorative
ring
Base plate
Light sensor
Under the decorative ring there are three controls:
Sensitivity of the motion detector
Delay for switching off the system
if no movement is detected
