Gentex Fire Alarm & Life-Safety Products
Gentex is one of the world's most trusted names in fire alarm and life-safety devices. The company built its reputation on detection - it introduced the world's first dual-cell photoelectric smoke detector - and today few manufacturers cover as much of an installation: 120VAC photoelectric smoke detectors and alarms, a full line of carbon monoxide alarms, plus strobes, horn/strobes, and bells for audible and visual notification. That breadth makes Gentex a single-source solution for schools, hotels, hospitals, dormitories, and commercial buildings.
A Detection Heritage Since 1974
Gentex Corporation was founded as a manufacturer of high-quality fire-protection products, built around a simple conviction: smoke detection could be better. In 1974 the company introduced a product that genuinely changed the industry: the world's first dual-cell photoelectric smoke detector. Less prone to false alarms and engineered to catch slow, smoldering fires early, it became the industry benchmark and the technical foundation for the products Gentex builds today, millions of which protect buildings across North America.
Smoke & Carbon Monoxide Detection
Detection is where Gentex made its name. Its photoelectric smoke alarms and detectors are listed to UL 217 and NFPA 72, with patented multi-position testing, onboard piezo sounders, and tandem interconnect, and the 120VAC hardwired families - including the widely installed 7100, 8240, and 9000 Series detectors - are among the most specified in residential and commercial buildings. Paired with Gentex carbon monoxide alarms like the GN-503, plus combination smoke/CO units, they give specifiers a coordinated detection layer from a name installers already trust.
Notification: Strobes, Horns & Bells
On the notification side, Gentex's audible/visual signaling appliances deliver strobes and combination horn/strobes with field-selectable candela, letting you cover a space efficiently with fewer SKUs to stock. The lineup also includes fire alarm bells and chime/strobes for audible and evacuation signaling across commercial and residential systems.
