Safe and Reliable: A CE-certified carbon monoxide alarm compliant with BS EN 50291-1: 2018. When dangerous levels of carbon monoxide are detected, a red LED flashes and an audible alarm exceeding 85dB sounds to alert your family.

Standby Indicator Function：You can quickly double-click the “Test/Mute” button to activate or deactivate the standby LED indicator. When activated, a lightbulb symbol appears on the display, and the CO alarm flashes a green LED once every 60 seconds while in standby mode. When deactivated, the lightbulb symbol disappears, and the alarm does not flash a green light during standby.

Digital Display: See the current CO level on a clear display, the minimum reading is 10 ppm. The CO detector has a detection range of 20 to 40 square meters.

Easy Intsalltion: Measuring just 60 × 105 × 32.7 mm, this small and unobtrusive Carbon Monoxide Alarm ，It can be placed free standing on any surface, or can be wall mounted with the included screws. It serves as a portable carbon monoxide monitor.

Low Battery & End of Life Warning: If the battery is low , the CO alarm beeps once every 60 seconds, and the yellow LED indicator flashes once. If the CO detector reaches the end of service life,the carbon monoxide beeps twice every 30 seconds, and Yellow LED indicator flashes twice.

Alarm Memory: Your CO alarm device will notify you of a CO alarm when you are away. If not silenced, the alarm will continue to sound until CO levels reach a safe level. The red "CO" light will continue to flash as a visual indication of previous activation.Please press the Test Slience key to let the alarm slient.

Sensitive sensing: The digital LCD display shows various real-time carbon monoxide concentrations ranging from 000 to 999PPM, the blue words light up automatically, and the display shows that the concentration exceeds 30ppm; 50ppm, alarm within 60 to 90 minutes; 100ppm, alarm within 3 minutes; 300ppm, alarm within 3 minutes. Note: When testing the detector, do not use gas to blow directly into the hole.

How to use the carbon monoxide alarm, It is powered by 3 AAA batteries(Not included the batteries). After the batteries are installed, it automatically turns on, then enters a 30-second countdown and enters the working mode. The PPM value can be seen at any time. The Indicator light and PPM number light will go out without any operation,But the green LED flashes once every 30 seconds to indicate normal operation.
