ᐅ Doorbell / intercom system connected to Fritzbox 7490

Okay, thanks in advance. So, you definitely need a Fritz!Fon for this as well?

I can’t answer this with a definite yes or no because we only use the Fritzfon here. However, it is often mentioned that only the Fritzfon guarantees 100% compatibility with the box. This is not always the case with DECT devices from other manufacturers.

Could you please test this with the Fritz Phone app? Thanks.

Hello everyone,
I’m bringing this up again because I need some planning advice on this topic.

In my case, it’s about a three-family house. Of the three doorbells/intercoms with door opener, one should be connected to a FritzBox on the first floor. That’s no problem. However, the doorbells/intercoms with door opener on the ground floor and the second floor should be connected to a different FritzBox. This second box is a 7390. Is it possible to operate two doorbells separately with this box? I have already looked on the Auerswald site, but the descriptions of the modules were somewhat insufficient. Is there a module that can manage this? If yes, which one? Or do you need three separate modules for this?

Thanks in advance!

Just a small tip – if you are considering an Auerswald TFS, you might also want to take a look at Wantec.

The 4051 model isn’t much more expensive but looks significantly better than the Auerswald.

Just as a side note: What kind of wiring do I need to connect such systems? I have the usual doorbell pushbutton outside and a simple chime inside in the hallway. Do I have all the necessary wiring? Of course, I have a Fritzbox, Wi-Fi, etc.
