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. The world's first dual-cell photoelectric smoke alarm.
The photoelectric 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.View Products
