I’m remodeling and having electrician run all new doorbell wiring in order to delete old interior doorbell which I never could get to chime with my original Ring Pro. Installing new Ring Transformer to use with new Pro 2 Doorbell at front door and moving original Pro Doorbell to back door.
The wiring diagram customer service referred to me incorrectly shows using Bypass Mode on the Pro Powerkit, but V3 has no bypass mode. They said to use the Two Ring Doorbells Pros/1 Transformer diagram, but this is not a workable option for the V3.
Hi @ShorLine. There is not a diagram for a Video Doorbell Pro and a Pro 2 to be directly connected to a transformer. I checked with my teams and they let me know that you are able to use the diagram for two Video Doorbell Pros and one transformer for reference. Except you will not be using a Pro Power Kit for the Pro 2, as the Pro 2 can be directly hardwired to a transformer. The Pro will be the only one using the Pro Power Kit in bypass mode. Verify you have the Pro Power Kit that came with the Pro, as the newer Pro Power Kits that come with the Pro 2s do not have a bypass mode. If you do not feel comfortable hardwiring, we strongly recommend consulting a licensed electrician. I hope this helps!
I was wondering about a similar issue so this helped. However I also would like to know how many I can run on one transformer.
The max transformer allowed is 24VAC/40VA which has an 80% max amp of 1.33 power draw. I assume from the wall adapter specs that each device needs about .5 amps to run.
All this said, is the reason the diagram only shows 2 doorbells on a transformer because that is the max that can be supported?
Under the assumption that they should never all be on at once, could you add more?
I ask because I have a rental that requires 4 doorbells but has no existing chime or transformer. I want to know if I can do one transformer for all 4 or if I need two transformers, one for each unit running two cameras.
Hi @DLC. There is no wiring diagram for four Doorbells to run off of one transformer because we do not recommend it. It is best to install two transformers with two Doorbells per transformer.
