You may wish to unplug the alarm and store in a plastic bag during the project. The following is a list of substances that at high levels can affect the sensor and cause an alarm. Methane, propane, iso-butane, ethylene, ethanol, alcohol, carbon monoxide, iso-propanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide, sulfur dioxides. Most aerosol sprays, alcohol based products, fresh paint, thinner, solvent, adhesive, hair spray, aftershave, perfume, auto exhaust (cold start) and some cleaning agents. 12 2520-7203-00.qxd 2006.4.7 3:50 PM Page 13 Normal Operation The Peak Level Memory Button When the Peak button is pressed the unit will display the highest CO concentration measured since the peak memory was last reset or the unit was powered. Levels between 11 and 999-ppm will be display although the unit does not display values below 30-ppm during normal operation. Although the peak level will display values below 30ppm the unit will never result in an alarm no matter how long the device is exposed to these levels. Peak Levels below 30ppm are for reference only and the accuracy of the concentration shown may not be as accurate as noted in the technical information section. DO NOT ignore readings above 30ppm or an alarming device. Refer to the following section “What to Do When The Alarm Sounds”. To Reset the Peak Level Memory… Step 1. Press the peak level button. Step 2. With the peak level button still pressed, press the test/reset button for two seconds and release. The number on the display will turn to “0”. The memory has now been cleared and the alarm will begin monitoring for CO within a few minutes. The Effects of CO Exposure When you breathe carbon monoxide, it enters your bloodstream through your lungs and attaches to red blood cells. These red blood cells, called haemoglobin, carry oxygen throughout your body. CO molecules attach to the red blood cells 200 times faster than oxygen, preventing the flow of oxygen to your heart, brain and vital organs. As CO accumulates in your bloodstream, your body becomes starved for oxygen. The amount of CO in a person’s body can be measured by a simple blood test, called a “carboxyhaemoglobin level” test . The early symptoms of CO poisoning are often mistaken for the flu – headache, dizziness, weakness, nausea, vomiting, sleepiness, and confusion. Breathing very high concentrations of CO can be lethal in minutes. Your Family at Risk for CO Poisoning Carbon monoxide is the number one cause of poisoning deaths. While anyone is susceptible, experts agree that unborn babies, small children, senior citizens and people with heart or respiratory problems are especially vulnerable to CO and are at the greatest risk for death or serious injury. 13 2520-7203-00.qxd 2006.4.7 3:50 PM Page 14 Normal Operation Where CO Comes From Inside your home, fuel burning appliances used for heating and cooking are the most likely sources of CO. Vehicles running in attached garages can also produce dangerous levels of carbon monoxide. A by-product of combustion, CO can be a potential problem from a number of common sources such as – a running automobile, a furnace or water heater leak or misuse of a fireplace, wood stove, charcoal grill, a gas range and space heater leak or misuse, and running portable generators where exhaust can enter the home. When appliances are in good working condition and with proper ventilation, lethal CO gas is vented outdoors where it quickly disperses. Even the slightest malfunction or misuse of any of the above sources can lead to a build-up of CO in your home that can become deadly before you even know it’s there. You don’t have to have ancient appliances to have a CO problem. Today’s more energy-efficient, airtight home designs can trap CO polluted air inside where it can quickly build to lethal levels. What You Can do to Protect Your Family To be safe, know the possible sources of CO in your home. Keep fuel- burning appliances, their chimneys, and vents in good working condition. Learn the early symptoms of CO exposure. If you suspect CO poisoning, move outside to fresh air and get emergency help. A blood test can confirm that CO has caused the symptoms of CO poisoning. Your first line of defence is an annual inspection and regular maintenance of your appliances. Contact a qualified Corgi installer or Transco (British Gas) for assistance. Remember, problems can begin after an inspection has been completed. CO can come from sources such as a crack in a furnace heat exchanger, or a leak in a water heater vent or a bird’s nest blocking a flue. Other sources of CO are nearly impossible to detect; even a change in the air pressure outside can turn a normally safe situation deadly. That’s why you need the 24-hour protection provided by a CO Alarm. Home Safety Tips What You Can Do... • Buy only appliances approved by a nationally recognized testing laboratory. • Choose fuel-burning appliances that can be vented to the outdoors. • Make sure appliances a...
