Lay out your system in advance. Determine the exact location of each station. We recommend a full complement
of wire be installed, even though you may not initially be installing the maximum number of stations available to your
system. This way, should you decide to add a station later, you can avoid running additional cables to existing stations.
Connect wires to terminals 01 & 02 if wire distance exceeds 200m (600’) total or more than 13 stations are used in your
KAH system.
Refer to the chart below and select the proper wire gauge to meet your requirements.
AWG WIRE SIZE 24 AWG 22 AWG 20 AWG 18 AWG
DISTANCE 330' 550' 830' 1300'
DIAMETER OF WIRE 0.5 mm 0.65 mm 0.8 mm 1.0 mm
DISTANCE 120 m 200 m 300 m 500 m
Referring to the diagram which illustrates your system, write your color code in the space privided. Begin your
installation with station #1. Note the position of the C terminal at each station. Be sure you wire each station correctly.
After installing the second station we recommend that the power supply be connected to the + and — terminals on
a phone and that a test be made for calling and talking between the stations. As each additional station is installed retest
between each station. Unplug power supply while making wiring connections.
