Home alarm system with carbon monoxide and smoke detection functions, high-precision LCD digital display, and a two-in-one smoke and carbon monoxide

【Dual Protection】This home alarm has two built-in sensors that display smoke and carbon monoxide (CO) concentrations on a large LCD screen, effectively protecting against the hazards of carbon monoxide and smoke in indoor air. Warm reminder: When testing, please place the alarm in a sealed bag and test it with an appropriate amount of carbon monoxide and smoke. 【Highest Alarm】When the carbon monoxide concentration exceeds 100 ppm, the alarm will sound, the red indicator light will flash, and the buzzer will sound once every 5 seconds. Please immediately close the valves, open doors and windows, and ensure good ventilation. When the smoke concentration exceeds 0.1 dB/m³, the alarm will sound, the blue indicator light will flash, and the buzzer will continuously emit an alarm sound exceeding 85 decibels. 【Sensitive and Fast】This smoke and carbon monoxide detector is equipped with an electrochemical carbon monoxide sensor and an advanced smoke sensor, capable of accurately detecting the risk level of carbon monoxide and smoke. If the detected concentration is too high, the detector will sound an alarm. If the gas concentration exceeds the set range, the product will respond quickly, immediately sounding an 85-decibel alarm until the ambient gas concentration drops below the alarm set value. [Ultra-Low Power Consumption] When the gas detector is working normally, the display is in standby mode, with only the indicator light illuminated; the green light flashes once every 30 seconds. The carbon monoxide detector consumes extremely little power in standby mode, with a battery life of up to six months. In addition, it has a low battery alarm function: when the battery is low, the red light flashes once every 10 seconds, and the LCD screen displays "Lb".
