Honeywell FS20X Flame Detector

The FS20X Multi-Spectrum Flame Detector is engineered to deliver fast, accurate, and reliable fire detection in demanding industrial environments. Building on the robust performance of the trusted SS4 model, the FS20X combines ultraviolet (UV), dual infrared (IR), and visible (VIS) sensing technologies to offer superior detection of a wide range of fire types—even in conditions where traditional detectors may fail. With an advanced UV solar-blind sensor and extended detection range, it significantly reduces false alarms while maintaining fast response times, even through smoke, oil film, or glass barriers that hinder older detector technologies.

Designed for maximum coverage and operational reliability, the FS20X features dual microprocessors that support high-speed digital sampling, self-diagnostics, and robust data handling. Its advanced signal processing ensures dependable performance across wider temperature ranges, and its long-range detection capability—exceeding 200 feet for a one square-foot heptane fire—reduces the number of detectors required across large installations. Additionally, the FS20X includes built-in memory for event logging and FirePic™ image storage, providing valuable insights for post-event analysis and compliance reporting.
