2 in 1 CO and Alarm Carbon Monoxide Detectors Detector

The 2 in 1 CO and alarm detectors are equipped with high-quality electrochemical sensors that boast remarkable sensitivity for detection. Keep your home and family peace with our carbon monoxide detectors, which also act as detectors.



Features:

The alarm will emit four short alarm beeps when carbon monoxide is detected and will emit continuous beeps when is detected. The alarm will also emit continuos beeps when both and carbon monoxide are detected at the same time. The red LED will flash while in alarm mode.

One "beep" every 30 seconds is an indication that the battery is low (need replacement) or the unit is malfunctioning.

Test button to verify that the unit is functioning correctly.

Green and red LED lights that indicate normal operation and alarm status.

The unit will "beep" and green LED will flash once as up.

3 digits LCD displayer is optional, Err on the LCD to indicate the unit is malfunctioning, Lb on the LCD to indicate it low battery and need replacement. 999ppm on the LCD to indicate CO level over 999ppm, if the Co leakage is less than 999ppm but over 30ppm, it would show its actual concentration.

Blue back light will be lighted when pressing the test botton or alarming.
