Upgraded Dual Sensors, 10-Year Lifespan Equipped with advanced photoelectric smoke and electrochemical CO sensors, this 2-in-1 detector provides faster and more accurate alerts against smoke and carbon monoxide.

When one alarm detects danger, all units sound simultaneously, ensuring every corner of your home is protected and everyone is alerted instantly. Pre-configured and easy to set up, no complicated pairing required.
10-Year Battery Life & Hassle-Free Installation Equipped with a powerful built-in 10-year lithium battery, this alarm requires no wiring or frequent battery changes. Simply mount it with the included bracket, screws, and anchors in minutes. Enjoy reliable, maintenance-free protection with lifetime free replacement support from KLTsenaife.
LCD Digital Display & Smart Indicators The clear LCD screen displays real-time CO levels (PPM) and battery status. Multi-directional sensing holes improve accuracy while reducing false alarms.
