Setup by the builder:
2 nutone doorbell
1 mechanical chime box (both doorbells are connected to this chime box)
1 transformer (Transformer is NuTone C907 16V, 30Va)
I attempted to install one of the Ring Doorbell Prob last night. See chime picture here, you can see I have the Pro Power Kit v2 connected. Everything is working properly, but there’s a small buzzing noise coming out of the chime and also the circuit breaker.
Called Ring support and they suggested I remove the Pro Power Kit v2 from the chime, and it’s making a even louder buzzing noise.
I know the Doorbell Pro supports ringing in my mechanical chime, but I actually don’t want that. I bought multiple Chime pro already.
Two questions:
- is the buzzing noise a concern? How to get rid of it?
- does my existing setup work with a second ring doorbell pro. Do I need a different transformer? Would I need two. Power pack installed to the chime?
- since I don’t need the mechanical chime to work, is there some steps I can bypass and not rely on it?
