CARBON MONOXIDE DETECTOR LCD CO LCD WIRELESS DETECTOR THE MOST IMPORTANT FEATURES COMPACT SIZE, HIGH FUNCTIONALITY PRACTICAL IN EVERY HOME HIGH QUALITY SENSOR IS CERTIFIED CE AND ROHS INCREASES THE LEVEL OF PROTECTION REMOVES THE FEAR OF DANGER IN ACCORDANCE WITH THE MOST IMPORTANT STANDARDS LCD SCREEN Advantages of the product Easy installation: Co alarm and comes with do screws for easy mounting on walls or ceilings. Battery replacement is convenient and has a long service life. High accuracy and reliability: Equipped with an advanced electrochemical carbon monoxide sensor that accurately detects carbon monoxide levels in real time. Instant warning: When the carbon monoxide detectors reach the alarm level, the CO sensor will detect CO, the red LED diode will flash, the blue LCD backlight will light up, the early warning will be provided by the loud 85-decibel alarm. Self-test function and informative LCD display: The device will emit a "chirp" sound, and the red LED will flash once when the power is turned on, "888" on the LCD display Then pressing the test button will emit sound signals and flash the red LED diode. Displays CO levels in real time and remembers dangerous CO levels since the last setting. The “Err” on the LCD display indicates that the device is malfunctioning. The "Lb" on the LCD display means a low battery level and the need to replace it. “000” is displayed on the LCD display for 3 seconds, and then goes do normal operating mode. Wide Application: Carbon monoxide detectors are suitable do living rooms, kitchens, bedrooms, offices, hotels, dorms and portable detectors on the go, etc. We recommend installing our carbon monoxide sensor also in the hallways.
