oor panel installation.
To make maximum use of the existing installation, pay careful attention to the following
indications.
Door pan l
e :
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
section throughout the entire installation.
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
does not work correctly.
We will join the independent call lines (the wires connected to the push buttons)
of the door panel to be replaced, and we will connect them to the new door panel's ground
terminal.
The remaining wires will be used according to the following chart:
It is essential to follow this order in all the installation points.
