CARBON DIOXIDE†. Colorless, odorless gas. Use detector tubes for screening. If greater than PEL, order gas sampling bags. *Note for sampling with Cali-5-BondTM, 10 liter, five layer aluminized gas sampling bag: This gas sampling bag has an integrated twist on/off valve (V-NPB-2/00) Septum (A-SEPT/.750). The nickel-plated brass connection On the most basic level, end-tidal CO2 (ETCO2) detectors are used to measure the exhaled concentration of carbon dioxide. The concentration of exhaled CO2 correlates to the arterial concentration of CO2, although multiple factors can impact the relationship. Carbon Monoxide sources in the home. CO is produced whenever a material burns. Homes with fuel-burning appliances or attached garages are more likely to have CO problems Common sources of CO in our homes include fuel-burning appliances and devices such as: Clothes dryers. Water heaters. Furnaces or boilers. First Alert uses the term “interconnect” to describe the way that certain alarms connect and communicate. When one alarm is triggered by smoke/CO/heat, the others sound to alert you where the problem is. There are a few different ways that alarms can interconnect with each other. The technology varies based on the alarm model you’ve chosen. Battery-powered smoke detectors are stand-alone units. But if you have AC-powered smoke detectors in your home and your home has been built in the last 10 years in the U.S., chances are they are wired together to intercommunicate. This sort of wiring guarantees that if one alarm in the house goes off, they all go off. . This detector can tell you the highest level of CO concentration in your home in addition to alarming. Replace your CO detector every five years. Have your heating system, water heater, and any other gas, oil, or coal burning appliances serviced by a qualified technician every year. Do not use portable flameless chemical heaters indoors. Carbon dioxide detectors work by measuring the concentration of CO2 in the air and triggering an alarm if it reaches dangerous levels. Carbon monoxide, on the other hand, is a toxic gas that is produced by the incomplete combustion of fossil fuels such as gasoline, natural gas, and wood. In Alarm: the detector is silenced for 5 minutes. It will sound again after 5 minutes if the carbon monoxide is still detected. NOTE: if high levels of CO are present (>350ppm), the detector cannot be silenced. If the CO detector goes off, leave the house immediately. Low Battery: the detector chirping is silenced for 12 hours. O2 analyzers can cost as low as $200. Oxygen sensors last from 2 to 3 years. Oxygen is the gas of life and is abundant in air at 20.9%. Detecting and alerting users of low oxygen levels is important for health and occupational safety. Oxygen can be displaced by other gases, becoming life-threatening when it is less than 19.5%. The new detectors integrate seamlessly into the rest of the system, and the existing monitoring plans. They're easy to install (via mounting bracket), easy to order online, and just as good-looking as the rest of the family, if we do say so ourselves. They may not technically be criminals, but smoke and fire are on the public enemy list.
