About This Item
- 10-Year Sealed Lithium Battery: A sealed battery powers the alarm for its entire 10-year lifespan — no more climbing ladders to change batteries at 3am. When the alarm reaches end-of-life, you simply replace the entire unit, ensuring you always have a fresh, fully functional alarm.
- Dual-Sensor Detection Technology: Uses both photoelectric sensors (for slow, smoldering fires) and electrochemical sensors (for carbon monoxide) to detect a broader range of fire conditions faster than single-sensor alarms. Earlier detection means more time to evacuate safely.
- WiFi Alerts to Your Smartphone: When an alarm triggers, you receive instant push notifications on your smartphone via the Kidde app — even when you’re away from home. Monitor all alarms in your home from one app with a complete status dashboard.
- Voice + Strobe Alerts: Announces “Warning: Smoke detected in the kitchen” in a clear voice, so you instantly know what’s happening and where. Flashing LED strobe light provides visual alerts for individuals who are hearing impaired.
- Wireless Interconnect – Whole Home Protection: When one alarm detects danger, all interconnected alarms in the network sound simultaneously throughout the entire home, giving everyone maximum warning time regardless of where the fire starts.
- Compliant with All Safety Standards: Meets UL Standard 217 (smoke) and UL Standard 2034 (CO), ensuring it detects dangerous CO levels at the thresholds required by NFPA and UL standards. Accepted by all US building codes and fire safety regulations.
- Easy Installation – No Electrician Needed: Mounts to any standard electrical box or ceiling with included hardware. Ideal for replacing hardwired alarms (with included adapter) or as new standalone battery-powered units. Average installation time: 5 minutes per unit.
