Perhaps the most important thing we learned from our testing is that smoke detectors have a limited range, which is one of the reasons modern building codes require a unit in every bedroom as well as in areas adjacent to bedrooms. To test effectiveness, we sprayed test smoke from an aerosol can directly at each device and timed how long it took the alarm to sound. We sprayed the test smoke from 5, 10 and 15 feet away. 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.
