Corridors
For corridors several options are possible . You can use
the same occupancy sharing as described before . But if
the corridor mode is used (mode 6), the OSD can "listen"
to several (or all 16) groups . This can be used for corridor
linking, keeping the lights on in the corridor if one of the
adjacent rooms or areas is still occupied . The first (lowest
number) group must be used for the corridor itself . In this
example the OSD units in the corridor have group number
1, but groups 2 till 5 are added .
Please note that this only works in corridor mode 6! To
enable this feature a special remote is needed . Please
consult your local Philips sales representative for further
information on this .

Grouping without gateway
It is possible to use occupancy sharing between OSD
units without gateway (or controller) . You need to use
a DALI power supply to provide system power on the
DALI (X-port) bus . Assigning a DALI Group address to an
OccuSwitch DALI BMS (LRM2090 and or LRM2092) can be
done by using the IRT9090 in the following way:

As soon as one (1) group is created Parallel Link is no
longer active . Parallel Link will become active again
once all groups have been removed .

D Note
It is not possible to assign a "Short address"
to the LRM209x by means of the IRT9090
or any other IR transmitter . If "Short
addresses" are needed they need to be
assigned via a different tool .
5.9
Energy measurement
The OSD has a special feature to deduct the amount
of energy that is being used by the lighting system .
The OSD will calculate the average value if it has been
commissioned and luminaires have been assigned to
groups . The OSD will take the number of luminaires and
the current setting for this average . So, for example one
luminaire at 100% and two at 40% will result in an average
of 60% . This is then used for the actual level (at the DALI
interface) .
Furthermore the OSD will calculate the energy that is used
and store this internally . The gateways are able to gather
this information . Usually the luminaire type in an office is
same everywhere . Simply fill in the system power of this
luminaire in the gateway and it will calculate the right
energy level .

How to commission a OSD with a network
As described before, the OSD units are grouped together,
share occupancy and send per group occupancy
information to the gateway .
