Ring intercom with Elvox 900-902

wiring

Hi there, I'm in trouble trying to install a ring intercom to my existing headset Elvox 900-902. Wirings into the headset are about: * 1 Yellow = Mic * 2 Blue = Headset * 3 Black = Common ![image|375x500](upload://mUgqMDhaB43r6klgikwqsdWPTOD.jpeg) Buzzers and Door opener are outside the headset, and both work with 12V AC. The power supply is somewhere in the building and is shared between the appartments. There is a way to connect ring intercom in this scenario ? I already have finger relays in order to convert 12V AC into any other required voltage.

    Hi @neobo. We have several articles on our Help Center about the Intercom [here](https://support.ring.com/hc/en-us/categories/7808852957972-Access-Control), which may help. You can also get in touch with our [Intercom support team](https://support.ring.com/hc/en-us/articles/10070641988500-Ring-Intercom-Support) via phone or email, and they can assist with installation and wiring questions. :)

      Hi @Caitlyn_Ring, I had already checked out articles and Support Team but I haven't received any support. Ring app tells me to connect cable with existing wires on pin 6 and pin 7 but: - pin 6 has not any cable attached (probably building elettrical system specific wiring) - pin 7 does not exists on headset (probably an issue in ring app :slight_smile: ) I have called support team 20th of april and scale up my request to a 2nd level: no response. I'm trying to ping every 3-4 days but again: no response come back from support team. I'm trying in community with other users due the lack of official support :sweat_smile: Can I try in a different way or channels ?

      @Mengolim it seems that your case is simpler than mine: you have short-circuit between green cable and blue cable. If the front door is the top side button, you can consider pink cable attached at pin 7. But a cable is missing: the buzzer (pin 6). Probably you have an external buzzer (like me). I suggest you to unmount your headset and check for a cable that is passing through that place. If you are lucky, behind the headset you can find the buzzer cable.

        I've found a solution for my usecase with a multimeter and some reverse engineering. For cable A the meaning are: | Ring Cable | Meaning | |--|--| | A-1 | Common | | A-2 | Speaker | | A-3 | Mic | | A-4 | See below | | A-5 | Door opener | | A-6 | Someone is calling at the door | With some tests I've seen that the A-6 button is working well with 12V DC but is not working well with AC. I've inserted a 12V DC power supply and a relay to convert voltage. After that the ring can detect signal from the front door. To unlock the door i figure out that ring intercom close the circuit between A-4 and A-5 cables. It is a very good feature to have a clean contact :slight_smile: In my case the doors open with VCC 12 AC and I have connected A-4 cable to VCC and A-5 to the cable to the door. Now It's work like a charm!

          @neobo I'm glad you were able to find a resolution that worked. Thank you for sharing this solution, as it might help other neighbors who have the same intercom as you. :)
