Doorbell Hardwire help

Hi all!

I’m looking at getting a ring doorbell, and want to make sure I can hardwire it before purchasing as I do not want to use a wireless, battery operated camera if possible. I’m very new to how doorbell wiring works (but am trying to learn!) and could just use some confirmation/explanation here as the house currently does not have a chime which seems to complicate things. I don’t want to just guess and potentially ruin the doorbell/transformer or worse, create a fire hazard.

If I’m correct here, the two wire bundles coming into the chime junction box are from the transformer and the doorbell. I’m assuming the white wires joined together connects the doorbell to the transformer directly, and the red wires would connect the transformer and doorbell to a chime. In this case do I need a resistor (like the pro power kit v2) to connect the two red wires in the junction box? Or am I completely wrong here? Surely the red wires need to be connected somehow…

I have a voltage meter to check the wires, but not sure what voltages I should/shouldn’t be seeing.

Any help is appreciated!

Wirewound Resistor for Ring Video Doorbell (1st Gen) and Ring Video Doorbell 2

Update… I tested the contacts on the transformer and showed no voltage on either screw. Going to replace the transformer (old one was 10V so needed to upgrade anyway) and will test to make sure the house electrical line is powered going to it.

Still could use some clarification on what I need to do with the wires in the empty chime junction box once I get the transformer working…

Hi @Razorcat. It is possible to connect a Ring Video Doorbell directly to a low voltage transformer. Do you have a specific model Doorbell in mind? This will determine how it is wired and what components are needed. You can find out more about hardwiring here. This page here also has some great diagrams. I hope this information helps!

@Tom_Ring Thanks for the response!

I decided and actually have just purchased the Ring Video Doorbell Pro 2, with the assumption I can get the wiring. If not I can just return/resell it.

The diagram for my situation (one ring doorbell, one transformer) shows to connect both terminals of the doorbell directly to the transformer which means all I would need to do is effectively cap the two red wires together in the picture of the old chime junction box. From what I can tell reading other articles, I thought you would need to install the power kit in bypass mode or at least add some sort of resistor instead of directly to the transformer to prevent damage to the doorbell.

Is this not the case anymore? I was looking at this particular article How to Bypass your Internal Doorbell with the Pro Power Kit V2 (for Ring Video Doorbell Pro) – Ring Help but it does not apply to my doorbell’s pro power kit V3 which does not have the bypass ports on it.

EDIT: I’m also a little confused on transformers and the articles using V, VA, and VAC all over the place. I have a 16v 30va transformer and the diagram recommends 8-24 VAC, will my transformer work for my situation? I believe V and VAC are being used interchangeably here, and so 16 is within the 8-24 range, but I want to make sure.

Hi @Razorcat. The Ring Pro 2 will not require a Pro Power Kit V3 to be used if you are bypassing your Chime Kit. The Pro Power Kit V3 only needs to be used if you are using an existing Chime Kit.

A 16V-30VA is a great transformer and actually what I recommend. If that is what you are using, you’re all set. I hope this information helps!

@Tom_Ring I just replaced the transformer and installed the doorbell directly to it and everything is working perfectly! Thanks for your help!

@Tom_Ring Sorry to ask a similar question but talk about diodes/transformers etc has got me all confused.

I’m based in Australia and our home has an existing Friedland Doorbell Chime (I think the company is now renamed Honeywell).

Is this existing doorbell chime already the right power requirements that all I simply need to do is unhook the existing doorbell button wires and screw them into my Ring Gen 2 Doorbell?

I’ve taken a photo of the chime for reference, it doesn’t seem to have any power details on it so not sure if it’s good to go or needs a transformer/diode or something else wired in?

Hi @beersuushi. At first glance, this chime kit does not appear to be compatible. I would check this list here to see if you can find the specific model to be certain. If it is not, you will either have to get a new chime kit or completely bypass it. Let me know if this helps!

Hi @Tom_Ring,

Thanks for the reply.

I’m happy to bypass the chime and instead use the existing wiring to power the Ring doorbell.

I think from Googling this is the existing chime wiring guide:

Do you know if there is a guide on how to bypass the chime and whether a transformer etc would be needed, I’m pretty sure there is a transformer already but unsure where it is located (may be in roof cavity) as there’s nothing I can see in the fusebox related to doorbell/low voltage.

Hey @beersuushi. This Help Center article here has information on how to wire directly to your low-voltage transformer. If you are hardwiring the doorbell, a transformer is required. Sometimes the transformer is located in a hall closet, basement, attic, or by the water heater. I hope this helps!
