connect wireless doorbell transmitter to old bitron door phone

[Juan Jose]

Hello everyone, I am trying to connect "VOXON Waterproof Wireless Doorbell" transmitter to my old Bitron Universal door phone, so that whenever the Bitron door phone rings, it also rings VOXON door bells connected to power outlets.

so far, I have been able to connect wires inside voxon transmitter so when both wires are connected, it rings the voxon bells but I don't know where to connect these two cable to bitron so it when bitron bell rings, it completes the circuit on VOXON transmitter by making connection between between voxon green-purple wires.

thanks a lot for your help!!!

You will need a relay with a 10-12 volt AC coil connected to Bitron 11 and 6.

This looks suitable but I can't be completely certain.

Terminals 13 and 14 to Bitron

Terminals 5 and 9 to doorbell transmitter.

You cannot directly connect the doorbell transmitter to the Bitron.

Please can you answer if this is going to be valid: https://www.amazon.es/gp/product/B00HPLOPQC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Also where should I connect Bitron and where Voxon.

thanks!

Looks like it should be. 12 Vac coil.

The coil connections to the Bitron are labelled B.

Then to the Voxon connect 1 and either 2 or 3. Not sure which is normally-open or normally-closed but if you get it wrong the Voxon will ring continuously.
