We will join the independent call lines (the wires connected to the push buttons)

The remaining wires will be used according to the following chart:
It is essential to follow this order in all the installation points.
All the wires of the installation must use the same conduit, especially those that carry
the video signal and ground.
The wires must not be spliced, frayed, nor touch metal parts, and must not vary in cross

The entire installation must be at least 40cm away from any other installation otherwise
there is a risk that the audio signal be exposed to interference, or that the system
