Kidde 120V Hardwired Smoke and Carbon Monoxide Alarm with 10-Year Battery Backup (2-Pack)

Ensure comprehensive life safety for your home with the Kidde 120V Hardwired Smoke and Carbon Monoxide Alarm 2-Pack. Powered by 120V AC house current with a sealed 10-year backup battery, this 2-in-1 combination detector eliminates battery changes and low-battery chirps over the entire life of the device. Engineered to meet UL/ULC/CSA standards, it features advanced sensor technology that reduces nuisance alarms caused by cooking while providing rapid detection of real smoke and carbon monoxide hazards. Clear voice alerts in both English and French explicitly announce the threat type, and interconnectivity support ensures that when one interconnected unit sounds, all units across your home activate simultaneously.

Key Benefits:

• 2-in-1 Smoke & CO Protection: Combines photoelectric smoke sensing and carbon monoxide detection into a single hardwired safety device.

• 10-Year Sealed Battery Backup: Built-in battery backup operates continuously for 10 years without requiring battery replacements or causing midnight chirps.

• Bilingual Voice Alerts: Crystal-clear English and French voice announcements identify whether the danger is smoke or carbon monoxide so you can take appropriate action quickly.

• Enhanced Nuisance Reduction: Advanced sensing technology filters out common steam and cooking fumes to minimize false alarms near kitchens and hallways.

• Interconnected Alarm Compatibility: Wirelessly or hardwire-interconnects with other compatible home units so every alarm sounds when a single hazard is detected.

• Self-Testing & End-of-Life Warning: Performs internal self-tests continuously and beeps after 10 years to notify you when the entire unit requires replacement.
