A house fire is a nightmare scenario. Working smoke alarms, and the early detection they offer, are an important element—maybe the most important—to help ensure the safety of you and your loved ones.
First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location
The best basic smoke alarm
Available in a two-pack, these alarms can interconnect so that they all sound at once. They also tell you which room the fire is in.We recommend
First Alert SCO501CN-3ST Combination Smoke and Carbon Monoxide Alarm with Voice Location
Same, with an added CO alarm
Similar to our pick but also equipped with a carbon monoxide alarm, these photoelectric smoke alarms with voice alerts can interconnect and allow you to identify threats by location.Another good choice
First Alert SA303CN3 Battery Powered Smoke Alarm
A good supplemental alarm
The First Alert SA303CN3 is slightly better at detecting fast, flaming fires than the rest of our picks, but it’s generally slower to go off, and it’s best as a supplemental part of a system.Another good choice
First Alert PR710 Slim Photoelectric Smoke Alarm with 10-Year Battery
If you need a 10-year battery
The PR710 can’t interconnect like our picks, but it does have a 10-year sealed battery, which some states and municipalities require.Another good choice
