NFPA 720, 2012 edition, Annex B Dangers of Carbon Monoxide, B.1 Carbon Monoxide, Table B.1 Symptoms of Carbon Monoxide Exposure Based Carbon monoxide (CO) is a colorless, odorless gas which at high levels can cause serious illness and death. CO alarms are widely available and should be considered a back-up to BUT NOT A REPLACEMENT for proper installation, use, and maintenance of fuel-burning appliances. CO alarms are designed to warn you of any unusual build-up of CO in your How do smoke and carbon monoxide detectors work? Smoke alarms and carbon monoxide detectors usually work on batteries; even wired devices will have batteries as a backup power source. They could also be a series of alarms connected throughout the building or operate individually. Both detectors are available at different price points – from Carbon monoxide detectors work in much the same way that smoke detectors do. They have mechanisms inside that react to the presence of carbon monoxide in the air to set off an alarm to alert you to the danger. This early warning allows you to get out of the house as soon as possible to seek fresh air and call 911. If you experience any issues at any time during your installation, please call TELUS at 1-855-591-1332. Carbon monoxide detectors in our smart home security plans work alongside your existing devices to send an alert to your control panel or your phone. . Carbon monoxide is an odorless, tasteless, poisonous gas that forms when carbons from fuels burn incompletely. It is lighter than air and released both naturally, such as from forest fires and volcanic eruptions, and through man-made processes. Some common man-made releases of carbon monoxide are from fumes of vehicles, small engines (like Then replace the battery with a nine-volt unit. 2. Verify the Sensor Functionality. Step 1: Light a match stick or cigarette and try to hold it for ten to fifteen inches directly below the air vents of the Nighthawk Carbon Monoxide detector. Step 2: Try to hold it for 3 to 5 minutes until your CO alarm beeps. What Does an End-of-Life Beep From My Detector Mean? Most carbon monoxide alarms last between 5 and 7 years. Even if the battery is still good, all detectors should be replaced after 7 years. This is because the sensor in the detector will not work as well, and when it comes to detecting CO, you want an alarm with a high functioning sensor. Carbon Monoxide Alarm FAQ. How Long Does A Carbon Monoxide Alarm Work? Carbon Monoxide (CO) alarms have a lifespan of 5-7 years, some up to 10 years, before they lose a sense of smell and cannot detect the deadly gas accurately. CO alarms actual life span can be shorter due to environmental conditions like temperatures and humidity. Using Gas Detectors to Measure Carbon Monoxide and Carbon Dioxide. When it comes to choosing an industrial gas detector for the workplace, a single-gas carbon monoxide detector will not measure carbon dioxide levels, nor does it work the other way around. The sensors are specific for each gas.
