Smoke Detector - 2-in-1 Smoke and Carbon Monoxide Detector - Carbon Monoxide Detection and Alarm All-in-One - Battery Powered (Batteries Not Included) - With Digital Display and Audible/Visual Alarm -

【Upgraded Dual Sensors】This 2-in-1 detector uses an advanced photoelectric smoke sensor and an electrochemical carbon monoxide sensor for faster and more accurate detection of smoke and carbon monoxide. Unlike standard detectors with a sensor lifespan of only 3 years, our detector has a lifespan of up to 10 years, protecting your home from these two deadly threats for longer. 【Real-Time LCD Screen and 360° Omnidirectional Airflow Design】The clear and easy-to-read LCD screen displays real-time carbon monoxide concentration (PPM) and battery status. Smart LED indicators provide visual warnings—red for carbon monoxide detection and blue for smoke detection—while the multi-directional sensor opening design minimizes false alarms and quickly detects hazards from all angles. 【One-Button Test, 85-Decibel High-Volume Alarm】Easily check the detector's functionality with the touch of a button. A powerful 85-decibel alarm ensures you're alerted even while you sleep. If a false alarm occurs, simply press the test button again to activate silent mode. The LED indicator will then flash for 10 seconds.
