With this intercom, one must ring the bell and the handset much be lifted before the door can be opened.
I tried both of the following options but none appear to work. I get the messages “The installation of your intercom system does not comply with the standard”
Option A)
Putting cable (+) into the clamp
Putting red and yellow cables into the clamp
Putting green and orange cable in the (+) position
Option B)
Putting cable (0) into the clamp
Putting red and yellow cables into the clamp
Putting green and orange cable in the (0) position
