The installation diagram shows the connection of an audio system with one or several door
panels for the same building.
If the system has one door panel only, override the wiring to the second door panel.
If the system has more than one door panel, wire the second panel as shown on the
diagram. In case of more than two door panels, wire them as the second is connected.
