When the carbon monoxide concentration in the surrounding air exceeds 50PPM, the detector will continue to emit an alarm sound reminder of more than 85dB, and the alarm icon on the screen will continue to flash. Carbon Monoxide & Propane Gas Alarm range: When 0%<GAS1/GAS2<5%LEL, the value is L-01, indicating that the GAS value is normal, no icon is displayed, and there is no sound alarm; when 5%≤GAS1/GAS2<8%, the value is L-02, the orange light flashes slowly, indicating a warning (in the initial default state, there is a sound alarm); When GAS1/GAS2 is greater than or equal to 8% LEL, the value is L-03, the red light flashes q
