How to connect your Ring Video Doorbell (1st Generation) directly to a low-voltage transformer without a pre-existing doorbell

If you don't have an existing doorbell but would like to avoid the need to charge the battery of your Ring Video Doorbell (1st Generation), you can connect your Ring Video Doorbell to a low voltage transformer.

For your safety, only use an existing doorbell transformer within the range specified below to power your device. For connecting to an existing doorbell system:
- Hardwired transformer (8 to 24 VAC, 50/60Hz, 5VA to 40VA)
Not compatible with: DC, halogen, and garden-lighting transformers.

Note: Some important facts for people planning to use this optional configuration for their Ring Video Doorbell (1st Generation):

  • The Ring Video Doorbell (1st Generation) can only be connected to an AC transformer or a Ring Plug-In Adapter (2nd Generation). The Ring Plug-In Adapter has been designed specifically for Ring Video Doorbells and has additional safety features not found in other DC supplies to ensure that you do not damage your Video Doorbell or power supply. Do not use any DC power supply not made by or certified by Ring.
  • Wires should be soldered onto the resistor and a wire clip can be used on the other end.
  • In addition to the equipment included in your Ring Video Doorbell box, you will need to purchase an electronic resistor.
  • Installation must be carried out by a qualified electrician.

A resistor is REQUIRED in place of a mechanical or electronic doorbell kit for this alternate configuration to work successfully.

Specs for the required resistor: 25 Ohm, 50 Watt, wirewound resistor

Do NOT install a diode.
