Ring pro doorbell wont ring

Installed and rings in app but does not ring my existing wired doorbell. I’ll check the device settings to make sure mechanical is selected. What is the purpose of the jumper? If I want the mechanical doorbell to ring does the jumper get installed?

Hi @gromaniuk. I would suggest looking over this Community post by Marley! It has great information on the Ring Pro and hardwiring. I believe the jumper you are referring to is called the Pro Power Kit and it is essential for a functioning Ring Pro. I hope this information helps!
