Gentex

Gentex was originally founded as a manufacturer of high-quality fire-protection products. Our team had long recognized a need for better smoke detection; in 1974, a product was introduced that literally revolutionized the industry.

This landmark product was the world's first dual-cell photoelectric smoke alarm. It quickly became the commercial industry benchmark because it was less prone to false alarms and was designed to quickly detect slow, smoldering fires. This technology became the foundation for our current products, millions of which can be found in schools, dormitories, hotels, and hospital buildings throughout North America and the world.
