New CO detector in CO

With more and more states passing legislation that mandate CO detectors in homes, installing these devices has become a nice add-on business for many fire installers. I saw a story this morning from Colorado about a new CO detector, called CO Authority, that monitors the level of CO in a house in an ongoing basis. This differs from the CO detectors I've heard about, which typically alarm only when there are dangerous levels of CO. CO Authority is installed directly on the furnace and shuts of the furnace when it goes into alarm. It's unclear whether it's designed to integrate with the alarm system. It is designed to be professionally installed, but by a "certified heating technician." The story says that the inventors are working with the NFPA to "with the National Fire Protection Association to develop a higher standard for detectors like theirs." Here's the story.
