WIRING
Lay out your system in advance. Determine the exact location of each station. Make a sketch showing the number of
wires required from each station to other stations. Assign station numbers at this time.
Begin your installation with master station #1. All masters included in your system should be connected and tested
before beginning sub station installation. A space is provided at the left of the diagram to write in your color code. Note the
position of C terminal on each master station. Be sure you wire each station correctly.
After installing your second station we recommend the power supply be connected to plus and minus and a test be made
for all functions calling and talking between each station. Unplug power supply while making connections.
Refer to the chart below and select the proper wire gauge to meet your requirements.
