Alexa Guard FAQs

What is Alexa Guard?

Guard is an Alexa feature that helps you keep your home and family safe. When you set Guard to Away mode, if an Echo device detects the sound of smoke alarms, carbon monoxide alarms, or glass breaking, Alexa can send you Smart Alerts, via notifications to your phone. If you have an ADT security system with Pulse or Control service, Alexa can also arm your system when you set Guard to Away mode, and you can opt to forward Smart Alerts to your security provider. And if you have connected smart lights, Alexa can automatically turn them on and off when Guard is in Away mode, to make it look like someone is home.

How do I set up Guard?

From your mobile device, open the latest version of the Alexa app, navigate to the Settings menu, and select Guard to begin setup.

What sounds can Alexa detect?

While Guard is in Away mode, the Echo devices in your home can help detect and notify you about the sound of smoke alarms, carbon monoxide alarms, or glass breaking. You can choose which sounds you want Alexa to notify you about during Guard setup.

Which Echo devices work with Guard?

Guard works on Echo, Echo Dot, Echo Plus, Echo Show, Echo Spot, and Echo Input. When enabled, Guard automatically works with all compatible Echo devices connected to your account. You can disable the feature on specific Echo devices within Guard Settings of the Alexa app.
