The First Alert SM210 is a slim, low-profile smoke alarm with a sealed 10-year battery, so there are no batteries to buy and no low-battery chirps for the life of the alarm. Precision Detection technology helps keep cooking steam and smoke from setting it off while still giving early warning in a real fire.

• 10-year sealed battery - no battery replacements or low-battery chirps for the life of the alarm
• Precision Detection technology reduces cooking nuisance alarms while providing early warning
• End-of-life warning tells you when it is time to replace the alarm
• Color: White
• Sold as a 2-pack

Note: Replace the alarm at the end of its 10-year life. Install per local fire codes.
