When a group of luminaires is in the same daylight

condition and needs to be operated at the same level, it is

possible to use one sensor to control multiple luminaires.

This can be done in two ways:
(a) Use an SR bridge which can then connect to multiple
DALI drivers. For details on SR bridge, please refer to
design in guide of SR bridge.

In case EasyAir SNS210 MC, SNS410 MC is connected to
multiple Philips Xitanium SR LED drivers, the number of
drivers is limited to 10. Not more than 4 drivers should

have DALI power supply enabled. To minimize unnecessary

losses, it is recommended to turn on only two DALI power
SGND
supplies. Each SR driver provides approximately 55mA of
current on the DALI bus, and EasyAir SNS210 MC is limited
to 250mA.

EasyAir SNS210 MC, SNS410 MC sends commands to all

SGND
connected drivers (using broadcast command); it does not
have capabilities to address individual drivers. The light
commands are sent as a broadcast command, so
occupancy-/daylight-based lighting control and task
tuning operate the same on all connected drivers. The
readout of energy information from the connected drivers
will not function. The energy readout of multiple drivers is
foreseen in our roadmap.
Warning:
i
Please note the DALI power supply can only be
turned on/off on the Philips Xitanium SR LED
driver through the MultiOne tool. For this
application, please also make sure all drivers that
are connected to the sensor have the same wiring
polarity. SR drivers are shipped with the power
supply on as default.
