The window (DALI group 1) and corridor (DALI group 2)
side speak for itself, but the additional groups are not so
obvious .
Additional presence (DALI group 3) is mainly used for
luminaires in the area that do not have a window or
corridor function nor daylight regulation and might be
changed separately from the main lights . Typical examples
are wall washers, task lighting etcetera .
Additional absence (DALI group 4) is used for additional
luminaires with a specific function . The most common
function is board lighting (for schools and meeting rooms) .
The OSD will accept luminaires with drivers that have
already a DALI group address programmed . Please be
aware that you need to program all drivers during the
DALI commissioning, it is not possible to assign a single
luminaire and leave the rest as it is .

Automatic control

This section shows how the automatic control of the
OccuSwitch DALI is based on occupancy and daylight
regulation .

Occupancy

The OccuSwitch DALI can automatically switch lights ON
when the area is occupied and switched them OFF when
the area is vacated . After the area is left unoccupied
for a set time period, the lights will either switch OFF
automatically or first dim to a background level for a set
time period .
On some occasions when there is very little movement,
the standard delay time of OccuSwitch DALI might be too
short . If movement is detected during the turn-off fade
(this takes 10 seconds) the lights will return to their "ON"
value and the delay time is automatically increased by 10
minutes (Smart Timer) .
