Gent S-Quad Detectors & Multi-Sensor Fire Alarm Devices
The Honeywell Gent S-Quad range is one of the most advanced fire detection systems available today, combining multi-sensor technology, sounders, voice alarms, and visual alarm devices (VADs) in a single unit. Trusted by installers and specifiers across the UK, Gent S-Quad detectors are designed to deliver maximum reliability, rapid response, and reduced false alarms.
Part of our wider Honeywell Gent Collection, the S-Quad range integrates seamlessly with Gent Vigilon and Nano addressable fire panels.
What Is the Gent S-Quad Range?
The Gent S-Quad is a family of addressable devices that combines:
Heat sensors
Dual-angle optical scatter sensors
Carbon monoxide (CO) detection
By using multiple sensing elements, S-Quad detectors provide false alarm immunity in challenging environments (such as steam or dust) while ensuring fast, accurate fire detection.
Many devices also include integrated sounders, voice alarms, and EN54-23 compliant VADs, providing a complete all-in-one life safety solution.
