The rest of the installation requires no modifications (no additional cable to the
master unit - two existing uniphone line wires are enough). It is very convenient
when installing additional units, for example on building upper floor.
1.- SLAVE UNIT INSTALLATION
Separate line to which all uniphones (or video display units) to be supported by a
slave unit will be connected. No other uniphones (or video display units) can be
connected to this line.
Installation and connections are the same way as for the installation of the master
unit. The only difference is the connection of uniphone main line.
The slave unit features an additional ML terminal (main line) to connect the plus
of the line of the upstream unit, the minus of the main line is connected to the
"LINE-" terminal. Refer to the wiring diagram on the next page.
Each panel must be powered from a separate transformer!
For video systems, a combiner (CDNVS) is used at the master unit and an indirect
combiner (CDNVSp) or an indirect combiner without a camera (CDNVSpbk) at
the slave units. The combiners are always connected to the EXMOD2 socket on
the unit board.
Note! Only those uniphones (or video display units) that are physically connected
"behind" (or downstream) the unit from which a call is to originate - can be called.
No “reverse” call is possible - a call to uniphones (or video display units)
connec
ted “before" (or upstream) the unit from which the call is to originate.
From unit A all uniphones (or video display units) can be called. From unit C
only uniphones (or video display units) No. 3 can be called.
