4.2.8 Master/Slave Operation
4.2.8.1 Light channel
In larger rooms often more than one motion detector is required. For detecting presence all over
the room, motion detectors have to be allocated in the whole room. But also in this case a detected
presence shall cause always the same settings independent of the place of detection. In this case one
detector operates as Master and an arbitrary number of motion detectors work as Slave.
The settings for the Master/Slave mode
a e ade i the su e u
light groups .
The Slaves must be configured as follows:
Adjustment to fully automatic (every movement shall be sent)
Set follow-up time to the same value as the Master
Set object type for output -
light to Swit hi g
Activate cyclic sending for the output object
o
Parameter: Output object 1 sends cyclic at ON
o
Guide value: 1min; for longer follow-up times, e. g. at 15min the cyclic sending can
be increased to e. g. 5 min in order to reduce the bus load.
Set Brightness parameter to brightness independent
The Master is parameterized as fully or half-automatic as desired.
A value of 10 minutes is recommended as the common follow-up time..
The objects have to be connected as follows:
All output objects of the Slaves (Object 0) have to be connected with the object external
motion - Slave (Object 5) of the Master.
The master now evaluates every self-detected movement as well as movement detected by the
slaves. The master then switches the light groups according to its own settings, regardless of who has
detected the motion..
4.2.8.2 HCV
The Master/Slave control can also be applied to the HCV channel. The settings for the slave are the
same as for the slaves for the lighting groups. However, the settings for the brightness values do not
apply to the HCV channel. The observation windows must be set according to individual
requirements.
The objects have to be connected as follows:
All output objects of the slaves (Object 40) have to be connected to the object External
motion (Object 45) of the master.
