About this item

2-in-1 Precision: the Smoke Detector Coupled with a Carbon Monoxide Detector Alarm Can Notify You Immediately When Smoke or Carbon Monoxide Concentration in Dangerous Level Is Detected, Which Helps You Escape from the Threat of Two Gases.
Stable Performance: with a Combination of Photoelectric Smoke Sensors and Electrochemical Co Sensors That Work Independently of Each Other, the Carbon Monoxide and Smoke Alarm Makes It Possible to Minimize False Alarms.
The LCD display is more practical: it can indicate the real-time carbon monoxide (CO) concentration in the surrounding air. When there is a CO concentration of 30-999PPM in the air, the screen will change to blue backlight and display the real-time concentration.
User-friendliness:You Can Examine the Alarm Once a Week by Pressing the "Test/Silent" Button of This Carbon Monoxide and Smoke Alarm, and You Will Have Easy Access to the Working Status of the Alarm through Failure and Low Battery Alarm; in an Emergency, the Alarm with Above 85 dB in Sound Will Inform Your Whole Family of Danger Immediately to Safeguard Health of Your Family Members.
We Provide a 12-Month Worry-Free Refund Guarantee and a 5-Year Warranty. If You Have Any Questions or Concerns, Please Do Not Hesitate to Contact Us at Any Time, and We Will Reply to You within 24 Hours. You Can fully Trust Our Products.
