Hi everyone,

I have a generic intercom device in my apartment with a Listen/Talk/Door button, I tried for the life of me to identify the manufacturer but no luck.

I’m hoping someone has run into this panel type before, here is my wiring:
The “Listen” button has a blue wire and a black wire to the speaker on the panel.
The “Talk” button has a yellow wire and a red wire to the speaker on the panel.
The “Door” button has a white wire.

…and a picture of the back of the panel:

Any help getting this setup and identifying which wire is which would be most helpful!

Thank you!
