When a group of luminaires is in the same daylight

condition and needs to be operated at the same level, it is
LED+
LED-
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 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
LED+
LED+
supply enabled. To minimize unnecessary losses, it is
LED-
LED-
RSET2
recommended to turn on only two DALI power supplies.
SGND
Each SR driver provides approximately 55mA of current on
the DALI bus, and EasyAir SNS210 MC is limited to 250mA.
LED+
EasyAir SNS210 MC sends commands to all connected
LED+
LED-
LED-
drivers (using broadcast command); it does not have
RSET2
SGND
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.
