OccuSwitch DALI sensor/controller
Applications
The OccuSwitch DALI is designed for use in offices and similar
applications like schools, including corridors, meeting rooms, etc. It
is optimized for recessed ceiling mounting and for mounting heights
between 2.5 and 4 meter.
The surface box allows surface mounting as well, with either recessed
wiring or surface-mounted ducts.
The advanced OccuSwitch DALI can be connected in parallel (max 22)
to cover larger areas like open plan offices. The use of different mains
groups or even phases is no problem.
Features
Window/corridor and dynamic offset control
For optimal energy savings the window and corridor luminaires are
controlled separately as indicated in the graph. Window-side lights will
switch off (or not switch on at entrance, the daylight override function)
when sufficient daylight is available. The corridor side however will by
default dim to minimum only, hence indicating to the user that the
system is operational. This feature can be disabled.
