Designed for easy installation without wiring, it emits a loud 85dB alarm to alert you instantly of hazardous CO levels, making it an essential safety upgrade for any modern home or workspace. ## Description Carbon monoxide (CO) is a colorless, odorless, deadly gas. It can be emitted by sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. A clogged chimney, improper venting, and attached garages can also cause carbon monoxide accumulation. Installing carbon monoxide alarms near heating stoves, kitchens, bathrooms, boiler rooms, etc. can help detect carbon monoxide leaks in a timely manner. This carbon monoxide detector is a reliable and easy-to-use device designed to protect you from the hazards of carbon monoxide. It has a highly sensitive electrochemical sensor that can detect even the smallest amount of carbon monoxide and emits an audible alarm when the detector is triggered. The device is powered by a replaceable 3x1.5V AA battery ，the carbon monoxide detectors is equipped with LED Digital Display， which can provide clear and easy to read detector status information and carbon monoxide concentration. It also comes with a test button that allows you to test the functionality of the detector without causing any error alarms. Carbon monoxide detectors are essential equipment for any household, and fire safety experts recommend using them to help prevent carbon monoxide poisoning. Includes: One carbon monoxide alarm, user’s manual. 12-months Warranty. Review: Malfunction in 4 months of use. Buzzes continuously with code 8 and green lights. Waste of money - One of the three broke down in 4 months of use. Buzzer made a continuous long buzz with both lights green and code 8. When I moved the alarm outside the house into fresh air and tested with new batteries the same issue persists. This means there is a malfunction. When I place another buzzer in the same room at yhe same moment while the faulty ine is buzzing, the second alarm makes no sound. This confirms that the buzzer broke down. I have added an image and a video. I cannot trust anymore that the other two alarms can make a correct detection in case of a real incident. Would be throwing them away. ## Features - Easy to Install: The co alarm and comes with screws for easy installation on walls or ceilings.
