    Honeywell FS20X Dual IR & UV Flame Detector

    Advanced Multi Spectrum (UV/Dual IR/VIS) Flame Detector.

    Based on the foundation of the highly successful and reliable SS4 detector, the FS20X detector represents a quantum leap in integrating Infrared and Ultraviolet sensing technologies. The FS20X detector is a Multi-Spectrum and UV/Dual IR/VIS and flame detector with a proven UV solar-blind sensor. FS20X delivers a faster response and fewer false alarms, performs in a wider ambient temperature range, with a much longer detection range compared to conventional UV/IR detectors.

    Conventional and older technology UV/IR detectors, using narrow band 4.3 micron IR sensors, will not always respond to smoky fires or if the detector lens is contaminated with oil and other substances since both UV and 4.3 micron signals are attenuated, obscured or absorbed by thick smoke or detector lens contaminations. All UV sensors will be attenuated to some degree.

    Superior Technology Dual microprocessors enable fast and reliable performance. The master microprocessor performs high-speed digital sampling and signal processing calculations while the slave microprocessor handles sensor data, performs communications, self-diagnostics and manages interfaces and memory for storing event log and FirePicTM data. The FS20X detector has a detection range in excess of 60 m (200 feet) (very high sensitivity setting) for the detection of a 0.1m2 (one square-foot) Heptane reference fire and has a field of view with a greater volumetric coverage than most UV/IR detectors. This means fewer detectors can be used to cover an area as compared to other manufacturers’ detectors.

    The FS20X detector using advanced algorithms for signal processing and fire and flame analysis to alarm to most fires in all industrial environmental conditions. If the detector’s UV signal is degraded due to heavy smoke or a contaminated lens, FS20X’s patented WideBand IRTM, Near Band IR and Visible sensors will still alarm to fire, albeit at a reduced sensitivity and slower response time.
