With over 60 years of experience and over 70 million gas alarms sold, our mission is to create safe and secure environments with the most advanced technology possible. Since creating the world’s first residential gas alarm in 1964, we’ve also created the first, and only, battery-powered wireless natural gas alarm. Our world-class gas sensor technology includes residential and industrial gas alarms, portable gas detectors, and odor sensors. Together, we can protect both people and property.
