Gentex was originally founded as a manufacturer
of high-quality fire-protection products. Our team had long recognized a need for better smoke detection,
and in 1974, introduced a product that literally revolutionized the industry.
Smarter Products
This landmark product was the world's first dual-cell photoelectric smoke detector. It quickly
became the 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.
