LINE TERMINATION SETTINGS (Z)
Refer to the previous chapter for correct Z line termination settings.
Default settings
All door phones are con
fi
gured by default with line termination on.
All brackets are con
fi
gured by default with line termination on.
All distributors are con
fi
gured by default with line termination off.
All column interfaces are con
fi
gured by default with line termination on (jumper between Z terminal
present).
The line terminal on/off jumper (Z) is not present on some video door phones (e.g. 1750/1, 1750/5, 1750/6,
1750/15, 1750/16 and 1760/6).
In this manner, in the typical case of system with calling station connected directly to the power supply unit
and apartment stations connected as
fl
oor extensions to a column, only the jumper of the termination of the
last distributor needs to be changed to the ON position.
