act as if local occupancy is detected;
• background lighting means that the OccuSwitch DALI
will switch all its luminaires on at the background
level .
• Daylight dependent regulation: luminaires will be
dimmed depending on the measured light level .
• Daylight switching on window/corridor side: when
sufficient daylight is available the luminaires (of the
given side) will be switched off .

Selecting a mode for an OccuSwitch DALI can be done in
two ways:
• For an easy selection, look up the mode based on the
application that the OccuSwitch DALI is used in . To
select the mode, find the application type in the table .
For example: when using an OccuSwitch DALI Advanced
in an open plan office, with parallel link connected, the
OccuSwitch DALI can be placed in mode 9: "Open plan
office with parallel link" .
• For a more advanced selection, select the mode based
on the parameters .
If the required set of parameters is not listed as one
of the modes 1-9, you may select to use a custom
application mode, which is mode 10 . For more
information on using this custom mode, please contact
your Philips representative .

In all modes, except mode 9, parallel operation means
that occupancy is truly handled as parallel . In other words
if one sensor picks up occupancy, all devices will react as if
their own sensor was triggered .
Parallel operation does not mean that the units act in the
same way!
Only the occupancy trigger is shared . The units will switch
off in different ways if timers are set in different ways . For
this the OSD has a digital potentiometer for the delay
timer . If set around 15 minutes, the unit will make the time
exactly 15 minutes . So if several units are used in the same
area, please set the timer at almost the same position .
When the complete area is now vacated all units will
switch off (or dim to background level) .
