Smoke and Carbon Monoxide Detector, Low Power High Precision LCD Digital Display, 2 in 1 Household Detector

2-in-1 protection: the smoke detector has two built-in sensors that can display the smoke and carbon monoxide concentration (CO) on a large LCD screen. This prevents the effects of carbon monoxide and flue gas concentrations in the ambient air. Reminder Please put the alarm in a sealed bag during the test and test it with a reasonable amount of carbon monoxide and smoke. Super alarm: When the carbon monoxide content exceeds 300 ppm, the gas detector emits an alarm sound, the red light flashes and the buzzer sounds every 5 seconds. The valve must be closed immediately and the doors and windows must be opened to allow internal air circulation. When a smoke concentration of more than 0.1% db/m is detected, an alarm is emitted, the blue light flashes and the speaker always emits a volume alarm of more than 85 dB. Sensitive and fast: the smoke and CO detector is equipped with an electrochemical CO sensor and a precision smoke sensor that can accurately detect the risk content of carbon monoxide and smoke. When the detected concentration is out of range, the product responds quickly and immediately emits an acoustic alarm of 85 dB. Until the amount of ambient gas falls below the alarm set value. Low energy consumption: during normal operation of the CO detector, the display is in standby mode. Only the indicator light works and the green light flashes every 40±2 seconds. The CO detector consumes very little power in standby mode and the standby time of the battery is six months. Low battery alarm function: when the battery is almost empty, the red light flashes every 10 seconds and the LCD screen will show "Lb".
