The First Alert SMCO210V is a 2-in-1 smoke and carbon monoxide alarm that tells you what the danger is and where it is. A friendly voice announces the type and location of the threat so you can decide how to get out, and the sealed 10-year battery means no battery changes and no low-battery chirps for the life of the alarm.

• Voice alerts announce the type and location of the danger to help you escape safely
• 2-in-1 protection against both smoke and carbon monoxide
• 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
• Sleek, low-profile design blends into walls or ceilings
• End-of-life warning tells you when it is time to replace the alarm
• Color: White

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