Installing A Ring Pro 2 Doorbell (wired)

ML420cdi

So if the new Ring doorbell needs between 16-24V to work...you think my existing unit maybe less than 16V?

What 'unit'? The grey transformer in your photo is AC to start with. You can look closer for the voltage, but again, it's AC.

The plug-in PSU that came with your new doorbell is 24V DC.

Apparently the power requirements vary.   The Ring site says this:-

"Ring Video Doorbell Wired requires 8 to 24V AC and 8 to 40VA. Ring Video Doorbell Pro and Ring Video Doorbell Pro 2 require 16 to 24V AC and 10 to 40VA"  (their bold)

Yeah so the grey transformer in the existing box is AC and the Ring Pro 2 needs 16-24V AC to work....so what chance the existing doorbell is working somewhere between those two figures?....

Worse case scenario I just wire up the Ring Pro 2 to the existing wires with my current doorbell?...presume it just would not work as the voltage would not be sufficient?

Just read

"

Hardwiring

A Ring Doorbell 2 can also be connected to an existing mechanical or electronic doorbell that operates at a voltage between 8 volts AC and 24 volts AC. Once connected, pressing the button on your Ring Doorbell 2 will trigger your existing chime."

Well, this sounds good - your transformer output is unlikely to be higher than 24V.

The only question is why your "Ring https://en-uk.ring.com/collections/accessories/products/video-doorbell-plug-in-adapter-gen-2 adapter"  is DC. Possibly, it operates as well with a DC supply.

The adapter is some kind of optional extra you can buy, I guess for those who don't have an existing wired set-up but don't want a battery unit that requires manual recharging periodically.

So if the voltage of your existing setup is between those two figures (16v-24V or 8V-24V depending where you get your information from) it should work...

I would definitely stick to the specified power requirement for the Ring device you actually have.   

In the case of the Ring Pro 2, that would be DC, and since you already have the specified power supply, I would use that.  

You can use the existing bell wire connection by disconnecting both ends, and connecting the door end to the Ring device, and the other end to your new transformer.  

Getting an electrician to swap the old chime unit for the new transformer seems like a good idea.

I'm confused...

Or is Ring Pro 2 not the same as Ring Video Doorbell Pro 2?

Didn't notice "AC" in the first quote.

This is the detailed Ring support page - what it breaks down to is... it's way more complicated than it really ought to be.

For the "Pro" devices, it's AC or a Ring-branded DC transformer like the one that the OP already has.
