OccuSwitch DALI BMS
The LDALI gateways will recognize the OSD unit both as sensor as well as driver (driver).
Up to 16 sensors will be recognized. Do not worry, all OSD sensor will work, and are divided into 16
groups. The gateway is not capable of recognizing the different sensors (yet).
The web interface allows you to give each OSD a short address; this will not influence the Group
settings made earlier. You can, of course, change group addressing to your need.
Depending on your needs you can use the group or short address methods to change the light
settings.

How does the OSD react to DALI commands?
The table below shows the reaction of the OSD and the luminaires behind it on the most common
DALI commands in comparison with a “normal” driver.
DALI command
Direct ARC
Effect on normal driver
Driver will set output level
accordingly*.
Recall scene 0 (first scene)
The driver will set the output
level as defined in scene 0.
Recall scene 1..15
The driver will set the output
level as defined in the
scene*.
SET DTR as scene
The value in DTR will be
stored as a scene
Effect OSD
All drivers connected to the
OSD will be set the output
level*. Daylight regulation is
suspended.
Automatic mode will be
enabled. The system will
NOT go to the output level
defined in scene 0, but to the
light level set during
commissioning.
The driver will set the output
level as defined in the
scene*. Daylight regulation is
suspended.
The value in DTR will be
stored as a scene, also for
scene 0!
* All commands will use fading, minimum and maximum level according to previous settings.
All DALI commands given to the OSD that affect the output level will start the occupancy timer. A
single DALI command will set the output level only for a limited period (the occupancy timer period)
if an area is not occupied. Lights will switch off after this period (or go to background level if set).
You need to repeat the DALI command to keep lights on a certain level. The repetition time must be
shorter than the occupancy timer period set in the OSD.
