Before you begin:

If there is an update available for your Ring App, please update it before you begin. Remind any shared users to update their app too. Updating the app ensures that everyone on your account will be able to see this new device.  

Select Set Up a Device

  1. Open the Ring app to the main dashboard.

  2. Tap Set Up a Device at the bottom of the screen.

  3. Scan the QR Code.

      Set up a Ring Alarm Base Station or Z-wave Sensor
      to continue through the setup process.
  4. Follow the in-app prompts to complete setup.

Pull out the clear tab

When prompted, pull the clear tab from the back of the device. This turns the Listener on. Your Alarm or Alarm Pro Base Station should find the Listener automatically.

As the Listener pairs to your Alarm base station, the Base Station’s LED ring blinks slowly, then quickly. Once pairing is complete, the LED glows blue for five seconds.

If the Listener does not pair successfully, the Base Station LED ring glows red. Try the pairing process again. Start by following the in-app instructions.
