Ring Doorbell 2 - wireing to existing door bell

My existing door bell system is integrated with the house’s M&S intercom system. All the existing door bell buttons are wired to the central M&S base unit and then the wires go out to the chime / speaker. I measured the voltage at the door bell button and it is 16v **DC. ** (Reason I had to go from a Ring Pro to a battery operated Ring 2).

Can I connect the Ring 2 to the existing door bell wiring?

Good question @bobtwo! Our Video Doorbells are not able to be wired to DC power, as they are only compatible with AC. For this reason, also, our Video Doorbells are not compatible with most intercom systems. I hope this helps! :slight_smile:
