Every detector sounded within 30 seconds at the 5 foot mark. Three smart smoke alarms –Nest Protect, Halo+ and First Alert Onelink – went off at the 10 foot mark. All but one of the smoke detectors, the Nest Protect, failed to detect dangerous levels of smoke at the 15 foot mark. How Much do Smart Smoke Detectors Cost?Always weigh the costs against the benefits you might get from a smart smoke alarm. On average, you can expect most smart smoke detectors to cost
around $100, though some units cost as much as $250, which can be up to 10 times more expensive than normal units. This can make replacing all of the existing smoke detectors in
your home very expensive. To keep costs down, consider using traditional units throughout your home with smart smoke detectors in main areas. Traditional smoke detectors typically cost between $10 and $40. Here are a few basic models that are popular on Amazon:First Alert BRK 3120B $27. 18 This hardwired alarm uses both photoelectric and ionization sensors to detect smoke.

It's a fairly simple process that took me about 5 10 minutes. MORE: Top Rated Wireless Home Security CamerasLike most smoke detectors, you can purchase the Nest Protect as either a battery powered model, or one that’s hard wired. App and PerformanceThe Nest Protect uses a split spectrum sensor that Nest says is good at detecting both slow smouldering
fires as well as fast burning ones. It's a photoelectric sensor, which is generally better at sensing smouldering fires ionization sensors are faster at quick burning fires, but are more prone to nuisance alarms, but Nest's sensor has a second wavelength that's better for picking up flaming fires. In addition, the Nest Protect has sensors for carbon monoxide, heat, humidity and occupancy. 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.
