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. How do CO detectors work? CO detectors measure the concentration of carbon monoxide in the air, triggering an alarm if it's high enough. There are several different kinds of CO sensors, including Article. Vocabulary. The Keeling Curve is a graph that represents the concentration of carbon dioxide (CO2) in Earth’s atmosphere since 1958. The Keeling Curve is named after its creator, Dr. Charles David Keeling. Keeling began studying atmospheric carbon dioxide in 1956 by taking air samples and measuring the amount of CO2 they contained. Ordering information. The Kangaroo™ CO 2 detector is an effective assessment tool that confirms correct NG and OG placement and helps avoid inadvertent tracheal placement - safely, reliably and immediately. Only the Kangaroo™ CO 2 detector incorporates a unique colorimetric paper technology engineered to display an easy-to-detect change in Carbon monoxide detectors are the fastest way to prevent CO poisoning. In your home, you can install a carbon monoxide alarm (or multiple detectors). They work much like your fire or smoke alarm by sounding a siren when they detect carbon monoxide. Step #6: complete your smoke detector installation. Reach up and slide the alarm into place against the mounting plate. If the alarm stays mounted and doesn’t dangle or fall out of place, it’s correctly installed. Note: Installing wired smoke detectors will likely require professional help. Accordingly, a national safety standard for carbon monoxide detectors published by Underwriters Laboratories (UL) requires that manufacturers build in a warning system to alert consumers that the unit is no longer functioning properly. 8.1 The unit (including the sensor) shall have a specified lifetime of at least 3 years from the date of Here are two that we’ve tested and can recommend: • First Alert Battery-Operated Carbon Monoxide Alarm and Smoke Detector. • First Alert Battery-Powered 3-Volt Smoke Detector. Once you’ve connected one of the above items, you can begin to customize how SmartThings will respond to these dangers. Start by tapping the prompt titled 3LAK.
