Office building with basic brightness function

Function
The lighting in a larger office is to be controlled using a Busch-Presence detector. Three Busch-
Presence detector is to be installed in parallel to detect the entire area.
The office building is to receive an illuminated glass front. If the lighting in the office is shut off
by the Busch-Presence detector a basic illumination is to remain.
DALI lamps are used for the implementation of different brightness values in the office.
Installation and settings
Fig. 58: Application example: open-plan office with illuminated glass front
For optimum detection, the installation position of the Busch-Presence detector should be
selected directly above the workstations.
The switch-off delay for such applications is to be set at approx. 10 minutes.
The Busch-Presence detector have an almost circular detection range. The areas must overlap
slightly to ensure that there are no gaps in the detection.
The load is connected to the main unit. The main unit is responsible for monitoring the
brightness and the switch-off delay. The extension units have the task of routing detected
movement and the respective brightness value to the main unit.
