Type of OccuSwitch DALI
After defining for each area whether an OccuSwitch DALI
or an extension sensor is used, you can select for each
OccuSwitch DALI which model to use, depending on the
need for communication with any neighboring application
areas and/or a building automation system:
• If the OccuSwitch DALI Basic is used, no communication
will take place with neighboring application areas or a
building automation system . It will operate stand-alone,
dimming and switching the light according to its own
measurements and that of any connected extension
sensors .
• If the OccuSwitch DALI Advanced is used, OccuSwitch
DALI can be connected to each other via parallel
linking . Each OccuSwitch DALI regulates the light level
according to its own measurements, but in addition
it will use the parallel link connection to report and
react on movement detection . If one of the connected
OccuSwitch DALI detects movement, it reports this on
the parallel link . Each of the other OccuSwitch DALI on
the parallel link are set to either:
• switch the local luminaires as if movement was
detected locally, or
• switch the local luminaires on, at a pre-programmed
background lighting level .
• If the OccuSwitch DALI BMS is used, the OccuSwitch
DALI will communicate with a DALI-capable building
management system

Note
In a DALI network it is not possible for OccuSwitch
DALI devices to exchange data directly with each
other . All communication is going via the DALI master .

Selecting the OccuSwitch DALI mode
Once lay-out of the OSD is designed (as explained in
section 3 .2), it has to be specified how the OccuSwitch
DALI must react on its movement detection, light sensor
and optional parallel link . The OccuSwitch DALI has 10
application modes (9 predefined and one customizable)
that define how the connected luminaires are controlled .
Table 12 shows the application modes and their
parameters . For an explanation of the parameters in this
table, see below:
• Auto switch-ON: the lights will automatically switch on
when someone enters the area .
• Auto switch-OFF: the lights will automatically switch
off when the area is vacated (and no parallel link
activity has taken place) for the duration given with the
potentiometer .
• Smart timer: when the lights automatically switch off,
and a movement is detected during this fade down, the
OccuSwitch DALI temporarily extends the movement
detection period (as given with the potentiometer) . The
smart timer value shown in the table defines with how
many minutes the movement detection period will be
extended .
