INSTALLATION
Do not attempt to install your intercom system until you have read and thoroughly understood the installation
procedure. Aiphone’s warranty is void if system is installed in a manner other than described in this manual.
Lay out your system in advance. Determine the exact location of each station. We recommend a full comple
ment 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. Do not connect wires to terminal P3 unless appropriate equipment is used. Phone system will
not operate if this wire is connected in parallel through system.
WIRING required: uSE PARALLEL CONDUCTORS, NOT TWISTED PAIRS.
TA-12H - 18 Conductors maximum TA-24H - 30 Conductors maximum

Begin your installation with station #1. A space is provided at the left of the diagram to write in your color
code. Note the position of the C terminal at each station. Be sure you wire each station correctly.
After installing your second station we recommend that the power supply be connected to the + and - terminal
lines at a convenient location and that a test be made for calling and talking between each station. As each addi
tional station is installed re-test between each station. Unplug power supply while making wiring connections.
To obtain the most efficiency from your power supply it is necessary to install the unit as near as possible
to the center of your communications network.
