Examples of wiring diagrams of the Control Unit
and various doorstations, door locks and buttons for exit
are given on Fig. 1-3.
Use a 75-Ohm coax
cable for video line between the doorstation and commutators. To avoid image distortion connect
an
resistor between the
and
terminals of that commutator
or distribution amplifier
, which
goes last in the video circuit (see Fig. 4).
