Description

Dual Protection from Smoke & Carbon Monoxide
For comprehensive home safety, pair a First Alert 10-Year Sealed Battery Smoke Alarm with a First Alert Battery Operated Carbon Monoxide Alarm. This provides robust protection against two distinct yet deadly threats. The SM210 smoke alarm features Precision Detection technology to distinguish between cooking smoke and real fires, and also detects smoke from burning synthetic materials, which helps reduce nuisance alarms. Its slim design blends seamlessly, and the 10-year sealed battery eliminates the need for battery replacements.

The First Alert CO400 Carbon Monoxide Alarm uses a highly accurate electrochemical CO sensor to detect invisible carbon monoxide. This battery-powered detector offers flexible placement, ensuring protection even during power outages. When elevated CO levels are detected, a loud 85-decibel alarm sounds that’s designed to alert even sound sleepers. This carbon monoxide alarm also includes low-battery and end-of-life alerts for timely replacement.

User-Friendly Operation and Certified Reliability
Both alarms prioritize user convenience and reliability. The SM210 features an easy test/silence button, with an end-of-life warning after 10 years. The CO400 is simple to set up and will begin monitoring once the battery is inserted. Their straightforward operation ensures critical safety functions are always accessible.

Optimal Placement for Enhanced Safety
For maximum protection, strategically place these alarms throughout your home. Install the Frist Alert SM210 smoke alarm inside every bedroom, outside all sleeping areas, and on every level. Similarly, place the First Alert CO400 Carbon Monoxide Alarm on every level and within each sleeping area. By integrating these effective and user-friendly alarms, you can equip your home with a comprehensive safety net against fire and carbon monoxide for years to come.
