Testing your Ring Alarm Smoke & CO Listener

After you add your Smoke & CO Listener to your Ring Alarm, you need to train the device to detect your smoke and CO alarms. If you have an emergency and don’t complete this test, it may not identify that the siren is sounding and won’t alert you to the fire or carbon monoxide threat.

The testing process is unique, and it’s important that you follow every step in this test process to avoid having a false alarm or missed events.

Step One - Press the Finish Listener Test button

You can complete this test using the Ring app during the Smoke & CO Listener setup process. If you skip this test, you can also start it by:

  • Tap Device in the menu.
  • Tap Alarm Base Station.
  • Tap Smoke & CO Listener.
  • Tap the Finish Listener Test.

Step Two - Put the Smoke & CO Listener in test mode

Tap the small Setup button on the side of the Smoke & CO Listener.  This will wake up the device and tell it to begin listening for the alarm sound for 15 minutes without dispatching the authorities.

Step Three - Press the Test Button on the smoke or CO detector

This will trigger the smoke or CO detector to sound an alarm. Your Listener should be close enough to hear the sound and detect the sounds.

You should see the notification on your app screen.

Note: If you are testing only a smoke detector or a carbon monoxide detector, you will only see one notification. If you are testing a dual smoke and CO detector, you should see both notifications on the screen if the test has completed successfully.

If you’re not seeing the correct notifications on the screen, you may need to reinstall the Smoke & CO Listener closer to the actual smoke and/or CO detector. You can press the smoke detector test button multiple times to ensure that the Listener is detecting every signal.

When you’re satisfied that the test has worked properly, you can press the Continue button.

Step Four - Press the Setup Button again

This will end the Listener’s test mode. Your Listener is now actively listening for sirens and will dispatch the authorities.

Note: If you don’t press the Setup button again, your Listener will automatically revert back to active mode after 15 minutes.

Your test has been completed.


In the future, if you need to test your smoke and/or CO detectors, you may accidentally trigger the Smoke & CO Listener and send a signal that will dispatch authorities that is actually a false alarm.

WARNING: To prevent false alarms, we recommend that you remove the battery from the Smoke & CO Listener before testing any smoke detectors in your home.

This is especially important if you use battery-powered smoke or CO detectors in your home. Before changing the batteries in your smoke and CO detectors, first remove the Listener battery to power it down, then change all batteries, and then replace the Listener battery to avoid triggering a false alarm.

Note: If you have a home with hardwired smoke and CO detectors, you only need one Smoke & CO Listener. If you choose to have more than one, know that testing the second Listener may trigger the first Listener to send a false alarm, unless you remove the battery from the first Listener before beginning the test.
