At 15 feet, the alarm activated at 28 seconds. It should be noted that Nest
Protect was the only smoke detector that passed all of our detection tests. Half the devices could not detect our test smoke from 10 feet away and only Nest Protect sensed danger from the 15 foot mark. All smoke alarms feature a loud blaring tone to alert you to potential dangers in your home. Nest Protect goes a step further by adding voice alerts that calmly tell you what kind of danger is present, where it is and how to proceed. If you have multiple Nest Protect smoke alarms installed and networked in your home, alerts will sound on each of them, warning everyone in your home about the danger. You can hush the alarm with the app if there's a false alarm. When Nest Protect detects threats in your home, it sends a notification directly to your smartphone. These real time notifications allow you to handle the situation from
wherever you are – you won’t always be home when disaster strikes – and contact local emergency services if necessary. Our testers determined that Nest Protect was by far the easiest to set up, mount and connect because of its intuitive design and clear instructions. It took just a few minutes from opening the package to having a fully functional smoke detector ready to go.
