Multiple doorbell pros on dual chime ringer

I currently have 2 Ring Doorbell Pros connected to my 1970’s era house chime. I keep getting low voltage notices and the cameras will go offline occasionally. My electrician says the chimes are bad. What do I need to replace this with to ensure both Pros work properly?

Glad you asked, @Kubi1and! You Doorbell Pro will be able to operate two chimes and power up through using a 16v 30va rated AC transformer. As you mentioned the chime kits failing, check out our Chime Compatibility list to ensure any new chime kits added will work as intended. Here is also our Wiring Diagrams which will have an option for your setup. I hope this helps! :slight_smile:
