Young children and household pets may be the first affected. Exposure during sleep is particularly dangerous because the victim usually does not awaken. The amount of carbon monoxide in the air is measured as ppm (parts per million). The graph below shows the important relationship between carbon monoxide in the air, exposure time and health effects. For most people, mild symptoms generally will be felt after several hours of exposure to 100 ppm of carbon monoxide. Higher levels will lead to more severe symptoms or death. M. What are the potential sources of carbon monoxide? Although many products of combustion can cause discomfort and adverse health effects, it is carbon monoxide (CO) that presents the greatest threat to life. Clogged Chimney Wood Stove Wood or Gas Fireplace Automobile and Garage Gas Water Heater Gas or Kerosene Heater Gas or Oil Furnace Gas Appliances Cigarette Smoke CO is produced by the incomplete combustion of fuels such as natural gas, propane, heating oil, kerosene, coal, charcoal, gasoline or wood. The incomplete combustion of fuel can occur in any device that depends on burning for energy or heat such as furnaces, boilers, room heaters, hot water heaters, stoves or grills and in any gasoline- powered vehicle or engine (e.g., generator set or lawnmower). Tobacco smoke also adds CO to the air you breathe. When properly installed and maintained, your natural gas furnace and hot water heater do not pollute your air space with carbon monoxide. Natural gas is known as a “clean burning” fuel because under correct operating conditions the combustion products are water vapor and carbon dioxide, which are not toxic. (Carbon dioxide [CO2] is also present in the air we exhale and is necessary for plant life.) The products of combustion are vented from furnaces and water heaters to the outside by means of a flue duct or chimney. Typical Carbon Monoxide Problems 1. Equipment problems, due to defects, poor maintenance, damaged or cracked heat exchangers. 2. Collapsed or blocked chimneys or flues, dislodged, disconnected or damaged vents. 3. Downdraft in chimneys or flues; this can also be caused by very long or circuitous flue runs, improper location of flue exhaust or wind conditions. 4. Improper installation or operation of equipment, chimneys or vents. 5. Air tightness of house envelope results in a lack of air for the combustion process. 6. Inadequate exhaust of space heaters or appliances. 7. Exhaust ventilation/fireplace competing for air supply. Caution: Correct operation of fuel-burning equipment requires two key conditions. There must be: • An adequate supply of air for complete combustion • Proper venting of the products of combustion from the furnace through the chimney, vent or duct to the outside CARBON MONOXIDE Alarm D. What do the LED lights mean? Power – Green This lights up green when the unit has power. It is normal for this light to be on while the unit is plugged in. If this light is off, the unit is not operating properly. Alarm – Red This flashes Red when the full alarm sounds. It is normal for this light to turn on when you press the Test/Reset button. The alarm signal consists of 4 rapid beeps repeating every 5 seconds, with the Red LED light flashing every time the alarm horn beeps. Low Back up Power – Yellow CO900 & CO920 Models only: Your Carbon Monoxide Alarm has a low level back-up battery warning. When the battery power is low, the yellow LED will flash every 5 seconds and the alarm will beep once every minute. During a mainline power failure or when unplugged to test the back-up power source (as per Section H) the indicator will light up and flash yellow, accompanied by a short beeping sound if the battery is low. This means the battery needs immediate replacing. It is normal for this light to turn on once or twice immediately after you plug in the alarm or after a power failure. E. What does the Digital LED Display Mean? FOR MODELS CO910 & CO920 ONLY: These models feature a Digital LED Display (Light Emitting Diode) that will show the level of carbon monoxide present when the unit senses concentrations of 46 parts per million (ppm) or greater. See section L for more information on the dangers of carbon monoxide. For any concentration below 45 PPM the display will show one dash “—” Reading the Digital LED Display F. What should you do if the ALARM sounds? If potentially harmful levels of carbon monoxide are detected, your unit will go into a continuous full alarm. The alarm signal consists of 4 rapid beeps repeating every 5 seconds, with the red LED light flashing every time the alarm horn beeps. WARNING Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can KILL YOU. If alarm signal sounds: 1. Operate reset/silence button; 2. Call your emergency services ( ), [fire department or 911]; 3. Immediately move to fresh air–outdoors or by an open door/window. Do a head count to check that all persons are accounted for. Do not reenter the premi...
