Gentex

Gentex has developed inventions that assist in smoke detection, voltage verification, and even in safer nighttime driving. The company revolutionized the industry with the world's first dual-sensor photoelectric smoke detector - a device less prone to false alarms, yet quick to detect slow, smoldering fires. Today, millions of Gentex smoke detectors and signaling devices can be found in hospitals, hotels, office buildings and other commercial applications throughout North America. Gentex continues to advance electro-optic technology along with its electrochromic dimming expertise as the company develops products and features for new and existing markets.
