When turned on, it listens for and alerts you to suspicious sounds. The first-generation Amazon Echo and Echo Plus, as well as the first-and-second-generation Echo Dot, do not support Alexa Guard. How Amazon Alexa Guard Works Once you've enabled the feature by saying, "Alexa, I'm leaving," your Alexa device will respond with "OK, I'll be on guard" and switch to Away mode. This enables the device(s) to listen for signs of an emergency, such as glass breaking, alarms, smoke detectors, crashes, and falls. If something happens, you'll receive an alert on your smartphone. Alexa Guard cannot call emergency services, such as 911, on its own. If you subscribe to a security service such as ADT or Ring, Alexa Guard also can send alerts to those services so they can increase surveillance of your home. In the event of an emergency, you'll still have to contact help on your own, either by calling 911 or requesting in-person assistance from your security service through their app. How Alexa Guard Works to Prevent Problems If you use smart lights in your home, you can connect them to the Amazon Alexa app so that Alexa Guard can turn the lights on and off randomly. This makes your home look occupied to would-be intruders. Users also can manage the lights remotely from the Alexa app, available for both Android and iOS devices. How to Disable Alexa Guard When you return home, turn Alexa Guard off by saying "Alexa, I'm home." If you have home security hardware that works with Alexa, such as an Amazon Ring Alarm, you'll have to enter a code to confirm your identity before Alexa Guard will disable. Devices Compatible With Alexa Guard Alexa Guard is available on Amazon Echo and Echo Dot smart speakers, and the Echo Plus smart home hub. The Echo Show smart display, Echo Spot mini smart display, and the Echo Input are also compatible with Alexa Guard and allow users to add Alexa features to other electronic devices.
