Detecting Level Range: 0~999PPM

Error: +/- 3PPM

Working state:

1. When the alarm is in the off-screen state, the green LED flashes once each 30 seconds, indicating that the alarm is in a normal state.

2. When the alarm detects CO concentration over 50PPM, the LCD screen lights up, indicating that the alarm has entered the alarm state.

3. When the alarm detects CO in the range of 50-99PPM,the device will alarm within 60-90 minutes,when the CO concentration is in the range of 100-299 PPM,the device will alarm within 10-40 minutes,when the CO concentration ≥300PPM, the device will alarm right away.

LCD screen display instructions:

‘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 not up to 999ppm but over 50ppm, it will show its actual concentration.

Package Include:

2 x Carbon Monoxide Alarm

4 x Screws

1 x User Manual

【Battery Powered, Easy to Install】Carbon Monoxide detector is powered by 3*1.5V AAA batteries (not included), low current consumption, extra long standby time. When the battery is low, the LCD screen will show”Lb”.Portable and easy to install, you’ll install it at home, in your car, or take it with you While you shuttle or camping.
【Instant Alert and High Accuracy】Advanced electrochemical CO sensor,provides high accuracy alarm. An early warning will be delivered through a loud 85-decibel alarm.
【Alarm Standard】50-99 ppm, alert within 60 to 90 minutes; 100-299 ppm, alert within 10 to 40 minutes; 300ppm, the device will alert right away. Note: While you test the detector, please do not use gas blow the hole immediately.
【LCD digital display and LED indicator】When CO gas is exceed 50 ppm, the LCD display will right away show the CO level. the LED indicator clearly informs the working status of the CO alarm detector: green LED indicates normal operation (flashing each 30 seconds), yellow LED indicates fault, and red LED indicates alarm status.
【Quality Assurance】 All CO alarms are strictly tested, when you have any questions about our CO detectors, please feel free to contact us, we can respond to you within 24 hours.
