Carbon Monoxide Detector, Smoke Detector, Home Alarm, Carbon Monoxide Smoke Alarm, High Precision Low Power LCD Digital Display

【2-in-1 Protection】This home alarm has two built-in sensors that display smoke and carbon monoxide (CO) concentrations on a large LCD screen. This prevents you from being affected by the concentration of carbon monoxide and smoke in the ambient air. Reminder: During testing, place the alarm in a sealed bag and test it with an appropriate amount of carbon monoxide and smoke. 【Super Alert】When the carbon monoxide level exceeds 300 ppm, an alarm will sound, the red indicator light will flash, and the buzzer will sound every 5 seconds. The valve should be closed immediately, and doors and windows opened to allow indoor air to circulate. If a smoke concentration above 0.1% dB/m³ is detected, an alarm will sound, the blue indicator light will flash, and the buzzer will always emit a loud alarm above 85 dB. 【Sensitive and Fast】Carbon Monoxide Smoke Detector Equipped with an electrochemical CO sensor and an advanced smoke sensor for the precise detection of carbon monoxide and smoke risk levels, if the detected concentration exceeds the range, the product reacts quickly and immediately sounds an 85 dB alarm. This continues until the ambient gas level falls below the alarm set point. 【Ultra Low Power Consumption】The gas detector's display will be in standby mode during normal operation. Only the indicator light is active, and the green light flashes once every 40±2 seconds. The CO detector consumes a small amount of power in standby mode, and the battery life is six months. It also features a low battery alert: when the battery is low, the red indicator light flashes once every 10 seconds, and the LCD screen displays "Lb".
