Replace intercoms to use opener

Hey guys,

I have the intercom “Elcom BHT-200” and I would like to install the Opener in addition to my Nuki Smart Lock 3.0.

Now my current intercom is not compatible to the opener. I had ordered one from Ritto, but realized afterwards that it is not compatible with the wiring system in our building. Now I thought that I would simply take a model from the Elcom brand that is compatible with the opener, instead of taking a third-party brand. My current Elcom BHT-200 model and the Elcom HAT-402 are both BUS-systems. Would that work for me?

I would be very grateful if someone could help me.

Best regards
