Open-plan office – Extension of the detection range with main units - Extension unit
DALI
Function
The lighting in a larger office is to be controlled using a Busch-Presence detector. Three Busch-
Presence detector are to be installed in parallel to detect the entire area.
The allocation of lamps should be kept flexible. E.g. in case that the office is reorganized at a
later point in time. The activation is therefore made via the DALI bus system.
In addition, the following was desired:
The lighting is to be switched on and off manually via a push-button.
■
The "Continuous Light" function as cleaning light.
■
The "Continuous OFF" function, e.g., for a video presentation.
■
Optionally, a slow switch-on and switch-off of the light can be activated via a dimming function.
The prerequisite for this are dimmable DALI loads. The times are settable via the smartphone
app "ABB Watchdog Remote control".
Installation and settings

Application example: DALI in an open-plan office
For optimum detection, the installation positions of the Busch-Presence detector should be
directly above the workplaces.
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.
