Carbon Monoxide (CO) Gas Detector

The JKD-626 is equipped with a carbon monoxide (CO) sensor to alert you to dangerous levels of highly toxic carbon monoxide, which can be fatal.

Intended Use

• In residential properties, including houses, apartments, and condominiums heated with wood and coal. Detectors should be placed near sleeping areas, as carbon monoxide poisoning often occurs while people are asleep.
• Garages: because vehicles running in enclosed spaces produce dangerous levels of carbon monoxide.
• Other rooms where fuel-burning appliances, such as furnaces, boilers, or water heaters, are used. Detectors should be placed near these appliances to monitor for CO leaks into the room.
• Campers, RVs, and yachts — carbon monoxide detectors are essential in campers, trailers, and yachts, as they are all equipped with combustion-based heating appliances, stoves, cooktops, and, in some cases, internal combustion engine-powered generators.

Advantages of a CO Gas Detector

• Reliable electrochemical CO sensor
• LCD display showing CO concentration in PPM (parts per million).
• Modern design
• Compact size
• Audible and visual alarm
• Certified to BDS/EN/ISO 50291-1
• Alarm memory function
• Power supply: 1 CR123 lithium battery (lifespan between 7 and 10 years)

Can I easily silence the alarm?

Yes, the sound on each detector can be silenced for 10 minutes by pressing the TEST button. This is enough time to check all rooms for the hazard.

About Carbon Monoxide (CO)

Carbon monoxide (CO) is a dangerous, highly toxic gas that is odorless and colorless. It is released during various chemical processes. In the home, the danger most often stems from the incomplete combustion of hydrocarbons. Sources include all types of heating appliances that use combustion: gas appliances, fireplaces, wood-burning stoves, and solid-fuel or gas water heaters. Other sources of carbon monoxide include vehicle exhaust and cigarette smoke.

Incomplete combustion most often occurs when oxygen is restricted to prolong the burning process—a common practice used to increase heat output from a stove at night. Switching the stove to “smoldering” mode carries the risk of incomplete combustion, during which this dangerous and highly toxic gas begins to be released. Since it is odorless and colorless, a person cannot detect its presence! Upon exposure to low to moderate concentrations of carbon monoxide, a person initially experiences headaches and dizziness. With prolonged exposure or exposure to very high concentrations—even for a short time—there is a risk of death. The greatest risk occurs during sleep, as the first signs of carbon monoxide poisoning will go unnoticed.

Why Is It So Toxic?

When inhaled, carbon monoxide binds to hemoglobin in the blood—the primary compound responsible for transporting oxygen in the human body—thereby reducing the amount of oxygen circulating in the body.

For the Curious

Carbon monoxide converts hemoglobin into carboxyhemoglobin, causing hypoxia. The chemical bond between carbon monoxide and hemoglobin is 230 times stronger than that between hemoglobin and oxygen, which is why hemoglobin converted to carboxyhemoglobin remains in that state permanently. Exposure to CO concentrations above 700 ppm (parts per million) converts 50% of hemoglobin into carboxyhemoglobin. This leads to severe or fatal consequences from carbon monoxide poisoning.

Carbon monoxide is produced by:

• Wood, coal, or liquid fuel (kerosene) stoves
• Gas stoves, cooktops, and heaters
• Blocked flues and chimneys
• Exhaust gases from internal combustion engines
• Barbecues

Symptoms of carbon monoxide poisoning

Support

The JKD-626 detector is factory-calibrated for carbon monoxide and does not require periodic calibration throughout its lifetime.

It only requires:

1. periodic cleaning of the housing to ensure that dirt or dust does not block access to the sensors. Depending on the environment, cleaning should be performed once a month to once a week (for very dusty rooms);
2. Battery life with a CR123 lithium battery is between 7 and 10 years.

Other than what is mentioned above, the detector requires no other maintenance.
