Hello. I connected my opener with the Urmet 1130/50 and my main problem is that after having completed the installation successfully (open works, ring to open works) - I have 1 problem.
My intercom no longer notifies me if someone else rings it! There is no sound coming to my house! The buzzer isn’t working. So I miss all my visitors/courier guys who ring my front door. They all believe I am not inside - but I am.
I have followed ALL instructions and everything else WORKS. How can I bring back the intercom buzzer sound?
