OccuSwitch DALI BMS (LRM209x)
Figure 3: Two cell offices linked to a BMS system
The OccuSwitch DALI BMS is a module that allows
connecting a maximum of 64 OccuSwitch DALI devices
to a DALI interface, for example a BMS system . Each
OccuSwitch DALI can be assigned to a maximum of 16
groups .
The BMS system can override the local OccuSwitch
DALI control . This allows, for example, to switch all lights
on when specific alarms occur or to keep all lights off
during the night . The BMS system can also retrieve status
information from each OccuSwitch DALI device .

Example
Figure 3 shows an example layout of two cell offices . Each
office part has its own OccuSwitch DALI BMS and two
rows of luminaires (a window row and a corridor row) . The
OccuSwitch DALI devices are connected to a BMS system .
Both OccuSwitch DALI BMS systems control the connected
lights automatically . The BMS system is used to monitor
the system and to override the local settings in special
situations .
Connectors
Un-commissioned system
Commissioned system
DALI output connector (DA)
The system regulates all connected
luminaires identically . This can cause
insufficient further away from the
window .
Up to four output groups can be set .
This allows setting correct light levels
for the luminaire groups .
For commissioning, see chapter 4 .
DALI input connector (X)
Complete standard DALI interface for connecting to any DALI system .
For commissioning, see chapter 4 .
