Extension movement sensor (LRM8118)
Figure 4: OccuSwitch DALI with an extension movement sensor
The extension sensor (LRM8118) allows extension of the
detection area of any OccuSwitch DALI . The sensor is
connected to the same DALI line as the luminaires . When
the extension movement sensor detects occupancy it
sends a trigger to the OccuSwitch DALI . The OccuSwitch
DALI reacts on this trigger as if it detected the movement
with its built-in movement detection sensor . This means
that the luminaires are controlled on movement detection
in both the main and the extension area .
The extension movement sensor is ideal for areas, such as
classrooms, that are slightly larger or differently shaped
than the standard movement detection area of the
OccuSwitch DALI . Up to two extension sensors may be
connected to one OccuSwitch DALI .
D Note
The extension movement sensor only extends the
movement detection range of the OccuSwitch DALI .
In some cases it is better to use two OccuSwitch DALI
units instead of an extension sensor . For criteria on
this, see section 3 .2 . 1 .
