TONNA 682526 intercom

Nuki Opener Other intercoms
1

Hello,

I have a TONNA 682526 video intercom.

The documentation sent by the manufacturer indicates the following meanings for the connection terminal block:

  1. DC+
  2. AUDIO
  3. GND
  4. Video
  5. R
  6. GND

Is this an analog or digital model? Do you have any idea how to connect it to the Nuki Opener? If not possible, can I replace it with a compatible model ?

Thank you!

Guillaume
