Product Description

Home Security Wireless Carbon Monoxide Alarm Detector With LED Display


Carbon Monoxide Detector(CO detector), use of high quality electrochemical sensors, combined with advanced electronic technology and sophisticated technology made of a stable work, long life and other advantages; can be placed on the ceiling or wall mount and other installation methods, simple installation,easy to use; Where carbon monoxide gas is present, once the concentration of carbon monoxide gas reaches the alarm setting value, the detector will emit an audible and visual alarm signal to remind you to quickly take effective measures to effectively avoid the occurrence of fire, explosion, suffocation, death and other malignancies.

Exceeding the temperature and humidity allowable range may reduce or lose the detection function.

Carbon monoxide (CO) is a highly poisonous gas that has no taste, colour or smell and therefore very difficult to detect with the human sense. CO kills hundreds of people each year and injuries many more. It binds to the hemoglobin in the blood and reduces the amount of oxygen being circulated in the body. In high concentration, CO can kill in minutes. CO is produced from poorly burning appliances, such as:
• Wood-burning stoves
• Gas boilers and Gas heater
• Oil and coal burning appliances
• Blocked flues and chimneys
• Waste gas from car garages
• Barbecues

1) The battery is correctly loaded into the detector with positive and negative polarity, The buzzer emits a "beep" sound and the detector starts to warm up for 40s. the LCD screen displays the count down, at this time, the detector has no detection function; after 40s, The detector enters the normal monitoring state and the LCD screen is normally closed. When the measured value of the measured gas in the air is bigger than 20×10-6, the LCD displays the real-time concentration of the measured gas in the environment.

2) When the concentration of the measured gas in the environment reaches the alarm setting value, the detector emits an audible and visual alarm indication.

3) Green power indicator, flashing once every 35 seconds, indicating that the detector is working.

4) Red alarm indicator. When the detector enters the alarm state, the red alarm indicator flashes rapidly and the buzzer sounds at the same time. The alarm of the alarm signal makes four cycles, each cycle is 100ms on/100ms off. Then turn off for 2 seconds until the CO concentration drops below the alarm setting value.

5) This CO alarm has an automatic self-test function to detect any failure of hardware, which is performed about every 1 minute in normal standby status.

Yellow fault indicator keeps on, the buzzer sounds 2 times per 8 second, indicating that the sensor has failed, at this time, there is no detection alarm function. Please contact Dealer for repair. It is extinguished after lighting for 50ms every 35 seconds, at the same time, sounds a "drip", indicates that the battery is under voltage (≦3.6V) and a new battery needs to be replaced.

Fault/Failure or error messages may be due to permanent damages such as short or open circuit of the sensor, or electric damage. Also, there may be temporary failures or errors due to slight shock of volatile chemical gases such as ethyl alcohol. In this case, the alarm can be recovered after 24 hours in pure air.

A permanent damage occurs when the failure or error information from the alarm is unrecoverable after 24 hours in pure air.


Please stop using permanently damaged alarm! Do not make unauthorized disassembly, repairing, or delivery to those authorized service points that are not designated by the manufacturer.
