Connecting Ring to old Friesland chime

Hi folks, I’ve been having trouble understanding where to connect the jumper cable on my old friedland chime - it is a version with 4 connections (0,1,2,3) and white wires in 1,2 and 3. There’s no markings at all to indicate which is trans etc. Anybody seen this before?

Thank you

Hi @user28673. You’ll need to determine which of the wires lead to the transformer and which of the wires lead to the front door. Since all the wires are the same color, this may make it more difficult to determine as you can’t look at the color of the wires at the transformer and doorbell respectively. I’d recommend consulting a qualified electrician to take a look so your Doorbell Wired can be safely installed.

Hi @user28673 did you manage to get this working, I have a very similar Chime set up to you and currently stuck as I can’t find the transformer. Thanks!
