Does the rRing Pro Power Supply require the 25ohm wire wound resistor?
I am gessing not but I can’t find a definitive answer anywhere.
Thanks - Moldy
Hi @Moldy1. Everything that’s required for the installation of your Doorbell Pro will be included in the packaging. A resistor is not needed when wiring your Doorbell Pro to an existing doorbell circuit, and you can learn more about the installation process here. I hope that helps answer your question.
