Each Ring Alarm device has a unique QR code and 5-digit code on the back.
These let you easily identify devices while working in the app. QR codes can be scanned when adding new devices to your Ring Alarm or you can enter the 5-digit code manually.
You'll find these codes on Ring Alarm devices, including the Contact Sensor, Keypad, Range Extender, Motion Detector, Smoke & CO Listener, Flood & Freeze Sensor, and the Panic Button. These codes can usually be found on the rear of devices as shown in these sample images below.
