Connecting Ring Video Doorbell 2 to Low Voltage Transformer (Without Pre-existing Doorbell)

If you don't have an existing doorbell, it's possible to connect a Ring Doorbell 2 directly to a low voltage 8-24V AC transformer (40V maximum) at 50/60Hz.

  2. Connecting the Ring Video Doorbell 2 to an AC transformer requires some knowledge of wiring and soldering. If you are uncomfortable reading wiring diagrams, hooking up wires or soldering them in place, consult a licensed electrician for assistance or use the built-in rechargeable battery to power your Video Doorbell 2.
  3. Wires should be soldered onto the resistor and a wire clip can be used on the other end. 
  4. In addition to the equipment included in your Ring Video Doorbell 2 box, you will need to purchase an electronic resistor. A resistor is
     in place of a mechanical or electronic doorbell kit for this alternate configuration to work successfully.
