Comelit bravo 5701

Come connettere questo interfono in maniera analogica? È un videocitofono a due fili

In English?

hello, I have a comelit Bravo 5701 with two wires.
I managed to connect the door opener by connecting two wires in parallel to the button. now I don’t know how to solve the problem of the ringtone that activates the opener.
yesterday I connected two wires in parallel to the speaker of the speaker that emits the sound but I don’t know where to connect it.

For the ring detection is yellow and green necessary (and sometimes the red too). Connect your speakers that way to the opener, that the ring signal goes over the yellow wire into opener, and over the green wire back into the speaker. Let me know.
