Hi Ricardo, thanks for answering, I understand how they work but electronics are not my thing, but with your answer I already have what it takes to test, I am suspecting that they did not connect it as I should, I wonder if there was already a problem with that. The microphones available to M and (first check that they have no power) and the speaker of the street front to P, what I notice is rare that the cables of the street speaker are which are (light blue) but are connected to another cable and I don't know where they are going.

One of the speaker has positive (or negative of the source) the other is the M of the phones. That line you have to open it (cut it) what comes from the phones to terminal M and the one that goes to the speaker to terminal P. Eye the two finite black wires of the transformer have 220V.

That source works with positive on the front (common microphone and speaker) and negative on the phones. One of the problems I see is that they did not respect the colors and did not identify the multipair pairs. For example, I see two braided reds connected to the positive of the source (impossible) should be red with another color (white, orange, blue, green, yellow, etc.) Well ... go to know who installed it. regards

Of course the braided red of which you speak is the positive that goes to the front (speaker and street mic) tomorrow I try with that to see how it goes, at night I publish the results, thank you very much Ricardo greetings!
