A:Answer You can connect it to the existing bell. It’s just two wires. It requires that the existing wires provide 16-24 volts. If not, you need to use the jumper cables that come in the box, use them on the bell wiring in your home electrical box. If you have an Eufy HomeBase it will also play doorbell sound on there. You can of course turn it off. If all fails, Eufy sells a dedicated wireless doorbell speaker for it.
