Ring Pro Doorbell
Hi, I suspect I know the answer but I thought I would get a second opinion. I have an existing hardwired doorbell (2007 construction). From a multi-meter voltage from the transformer is 20V. Issue I have is that the doorbell is wired with cat-3 24/2 wire. I do not know how many VA the transformer is providing (cannot see any markings on transformer) but I suspect not too many given the size of the wire.
Ring tech services responded (very quickly I might add) to a question with the following statement. "The power requirements needed for Ring Doorbell Pro is 16-24 volts AC. The transformer itself has an indicator of how many voltages per contacts. The two wires on your Ring doorbell should be connected to the 16V contact and the other wire to the 24 V contact or 30 V. If your transformer is only up to 20V this will make it under powered."
I am a bit confused with his reply but my basic question is will the low-voltage wiring (24/2) be sufficient to provide power to the ring doorbell or will it draw too many VA? The Ring website support page shows a wiring diagram with a recommended 16V-30VA transformer.
Running a new wire is not practical based on house design.
Thanks in advance, Jason
