• 【Battery-Powered, Easy Installation】The carbon monoxide detector is powered by 2*1.5V AAA batteries (not included), offering low power consumption and extended standby time. When the battery is low, the LCD screen will display "Lb." Portable and easy to install, it can be placed at home, in the car, or carried during travel or camping. Use the included screws to mount it on walls or ceilings, or affix it easily with double-sided tape (not included)
• 【High Sensitivity and Fast Response】Equipped with an advanced, high-sensitivity electrochemical CO sensor, this detector delivers precise alerts and quickly detects carbon monoxide levels. To ensure full protection, place one detector on each floor and in every bedroom of your home
• 【Alarm Standards】If carbon monoxide levels exceed 30ppm, the alarm's screen will light up and display the CO concentration. When the CO level reaches 100ppm, the detector will immediately sound an 85dB alarm and flash a red LED warning! Note: Do not blow gas directly into the sensor when testing the device
• 【LCD Digital Display and LED Indicators】The LCD screen instantly shows CO concentration when detected. LED indicators clearly indicate the detector’s operational status: Green LED: Normal operation (flashes every 60 seconds). Yellow LED: Fault detected. Red LED: Alarm state
• 【Quality Assurance】This CO alarm has undergone rigorous quality testing and is certified by CE, UL2034, ROHS, and FCC
