I have an intercom to open the front door of my home, model Auta 752105. I would like to connect the T2 double relay so that I can open the door remotely. Is this possible? If so, could you tell me the best way to connect it? (Attached is an internal image of the connection.)

Hello, I think there will be no problems, the T2 relay has dry contacts. You need to search the net for which points the door On signal is sent and connect the relay there. I will try to find your diagram. In the meantime, familiarize yourself with the capabilities of the T2. Rele T2, let's talk about it again
and ± for connecting T2 power (If t2 supports those voltages.)
Hello, the T2 relay has the ability to be powered by +/-24 volts.

Hello, there’s a microphone drawn there😂
You are right, then I do not know where door On signal is located
Green white green, what could this be <–?
I’ve just checked that Auta 752105 works with 24 Vdc

This is the AUTA manual

Hello, the intercom system covers a neighborhood community consisting of two buildings and 65 apartments. The only access I have is to the cables in the image above, which are in my apartment.
The intercom system controls two doors: one is the main entrance to the neighborhood community (where the two buildings are located), and the other is the entrance to the building where my apartment is located, so there must be two door opening circuits. Looking again at the initial image and comparing it with the last diagram you show, it seems that the orange and orange/white wires are the “+” part of the two door opening circuits, and the brown and white/brown wires are the “-” part of the two door opening circuits. What do you think?
And now the question is, how does the intercom know which door to open if I only have one open button? I understand that when you call home from the door you want to open, the correct circuit is activated, and that circuit is the one associated with the door open button at that moment.
I just tried it and it doesn’t work. When I bypass it, I hear a ringtone from the intercom, but it doesn’t work; the door doesn’t open.
This is the connection to the front panel of the intercom (see attached)
