Hello, I am trying to install the Ring Pro. My existing doorbell uses a 12V output. Do I need to change to a 16+ volt transformer or will the 12V work?
Good question @dickrjc! The Doorbell Pro requires 16 - 24 volts of AC power to operate. If you are using an existing chime kit, I recommend also checking what it’s rated for, voltage-wise, and if it is on our Chime Kit Compatibility list.
Feel free to check out some of our power supplies on our Accessories page. I hope this helps!
