In our lab, we tested the Nest Protect as with all smoke detectors by spraying an aerosol smoke detector tester spray from 5, 10 and 15 feet away, and timing how long it took each alarm to go off. At the 5 and 10 foot mark, the Nest Protect sounded after 18 seconds. At 15 feet, the alarm activated after 28 seconds. Moreover, it was the only device to pass all of our tests. Yes, a siren is very helpful in alerting you to a fire, but doesn't provide any information other than that. Nest Protect is different in that it also provides spoken alerts, which not only tell you the nature of the emergency smoke or carbon monoxide, but also the room in which it's occurring. The Nest Protect runs self checks to ensure that everything is working as it should; while this includes turning on its siren once a month, it's a welcome feature. The app gives you advance warning, which is also nice. The Nest Protect was the only smoke detector to pass all of our tests.
