WHAT IS CARBON MONOXIDE (CO)
Carbon monoxide (CO) is a highly poisonous gas that has no taste, color, or smell and therefore very difficult to detect with the human sense. CO kills hundreds of people each year and injures many more. It binds to the hemoglobin in the blood and reduces the amount of oxygen being circulated in the body. In high concentrations, 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

Symptoms Indicated by Carbon Monoxide Concentration Poisoning

FUNCTION AND INDICATORS

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

WARNING

• Demolition, replacement, damage to parts, and collisions, may reduce or lose the detection function

WHERE TO LOCATE THE CO ALARM
Install the alarm in the bedrooms common activity places, or places where you think may generate or leak carbon monoxide. It’s suggested to install at least one alarm in each floor of a multistory building to ensure everyone can hear the alarm while sleeping.

WARNING
Ideally, it is advisable to install a detector in every room that has a fuel- use appliance.
However, if there is more than one burning appliance and the number of detectors is limited, the following points need to be considered when determining the location:

• If the bedroom has a burning appliance, you need to install a detector in the bedroom;
• If there is a chimney-free or common flue gas appliance in the room, a detector must be installed in the room;
• If there is an electric appliance in a more-used room, such as a living room, a detector needs to be installed in the room;
• In a bedroom and living room, the detector should be as far away from cooking appliances and sleeping areas as possible;
• If the appliance is in an infrequent room, such as a boiler room, the detector needs to be installed outside the room so that the alarm sound can be heard easily.

Detectors and fuel-use appliances should be located in the same room;

• If the detector is mounted on a wall, its height should be higher than any window or door, but it must be at least 150mm from the ceiling. If the detector is mounted on the ceiling, it should be at least 300mm from any wall.
• The detector is at least 1m to 3m away from the potential gas source;
• If there is a partition in the room, the detector should be on the same side of the partition as the source of potential gas;
• In a room with a beveled ceiling, the detector should be on the high side of the room;
• The detector should be located very close to the area where the occupants often breathe.

WARNING

• Drop, collision, or complete loss of detection function.
• Please avoid the following places unsuitable to install an alarm to avoid damage or unnecessary false alarms or no alarms.
  • Do not install the alarm behind the drape or furniture
  • Do not install the alarm in a path of air discharged from a furnace air conditioning vent or ceiling fan
  • Do not install the alarm in places where the temperature can easily drop to -7 0°C or rise to over 40°c
  • Do not install the alarm in places with much lampblack or dust, which will easily block its sensor
  • Do not install the alarm in too moist places
  • Do not install the alarm directly above a sink or cooker

INSTALLATION DIAGRAM

Note: Please use the same specification of a 7.5V battery. If you use other low-capacity batteries or mix the batteries of different manufacturers, it will shorten the life of the detector; when the battery is exhausted, the machine can not detect carbon monoxide, please Replace the battery with a new one.

WARNING

• Be sure to test the product to ensure that the detector is functioning properly.
• Water mist or drip may cause electric shock and reduce the detection function.
• Cutting off the power supply will not be able to play the detection function.

HOW TO INSTALL THE CO ALARM
This CO alarm is powered by three LR6 AA batteries and requires no additional wiring. Make sure the alarm can be heard from all sleeping areas or place several alarms.
Install the alarm in places easy to test and operate and replace batteries. At the time of fixing the alarm on the wall, the installation height must be over 1.5m and 0.3m lower than the ceiling, with 1.5m away from room corners, wall edges, and large furniture.

Wall mounting installation steps

1. Having established the mounting location ensure that there is no electrical wiring or pipe work in the area adjacent to the mounting surface.
2. Mark the two mounting hole locations in a wall 5.5cm (2.165in) and drill holes in the marked position. Insert wall plugs into the holes.
3. Lock the mounting bracket with the screws. Tighten the screws properly.
4. Insert three AA batteries in the battery compartment with the correct polarity mark on the rear of the detector. After a beep, close the battery cover, and then test whether the alarm is functioning properly by pressing the “TEST” button on the flank of the detector to make sure it is normally functioning.

   CAUTION: for the safety of the user the CO alarm cannot be mounted without its batteries. When replacing the battery, test the alarm to make sure it is a normal functioning.

OPERATION INSTRUCTIONS

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 40, 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 LCDs 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. Fault: The yellow fault indicator keeps on, the LCD “Err”, and the buzzer sounds 2 times per 8 seconds, indicating that the sensor has failed, at this time, there is no detection alarm function, please contact the dealer for repair. End of Life: The sensor’s max life is 7 years, when the life of the sensor ends, it will have a prompt, the buzzer will sound 3 times and the yellow indicator will flash 3 times at the same time per 60 seconds, and the LCD displays “FAL”. Please change a new detector.
   Low battery: The battery capacity level is detected every 50 seconds, when the battery is under low voltage (53.6V), it will have a prompt, the buzzer sounds a “drip”, and the fault indicator flashes once, frequency under 60 seconds. New batteries need to be replaced immediately.
   Permanent damages such as short or open circuits of the sensor, or electric damage will lead to fault/failure or error messages. 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.
