ALCAD TED-001 Digital 2 Wire

Hello everyone.

After I used and I am very happy with all Nuki Stuff, I am tried to install Nuki in my parents home while I found some “problems” with Opener.

My parents Intercom is 2 wire so I think I should install like Michel Mayoral said in this post but not sure because I saw that some Intercoms need a resistance and I do not want to burn it and need to buy a new one find it out how to install…

The Intercom is an:
TED-001 E7

You can see the pictures of the intercom inside with front and back of the circuit.

My knowledge about electronics is very lower-basic.

Regards and thanks for your time.

Looks like a BUS System.
For this you need just the two wires of the first picture :blush:
I would try the config for BUS Systems.

Thank you I’ll try and report!

I tried but I got some errors after I setup with debug mode active and latest stable firmware which is 1.4.6

I connected:

“BUS -” and Nuki Black together as is in the pic.
Green and orange together where was the Brown (“BUS +”) in the picture.
“BUS +” (brown in pic) to the clamp and also to the clamp red and yellow.

I got the errors in the pics.


Did you try to change the cables? Not always is BUS+ how it seems.
Try the way from this plan :blush:

I will try to change BUS+ and BUS- by the way but yes, that’s the schema I used.

BTW. In other topics wrote some ppl to add just the red and black cable works too.
Red in to BUS+ and Black in to BUS- both as second cable without remove on :blush:

I’ll try, thank you!

Does not work :cry:

Anyone can help?

Any news with your Alcad intercom?

No, sorry. Finally I just did not install it because I got a code for the Intercom and now I can go in with a password.

Anyway if someone can fix it or want me to test I can do it, but this installation is not on my house so I would need the test you want to make.

I have the same and still not found how to make it work.
Contacted with Nuki Support but still not supported.
Found some useful information here:

Definitely a bus system, ring call is detected, but opener signal does not. Also is needed to hang up to open manually.

Anyone make it work? Any workaround?
Can it be tested as other door without hang up the speaker?

Best Regards
