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 is a Multi-Spectrum and UV/Dual IR/VIS fire and flame detector with a proven UV solar-blind sensor. The FS20X exhibits faster false-alarm free response to fires over a wider temperature range and 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 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. Also, these old technology UV/IR detectors will not alarm any fire if they are installed behind ordinary window glass.
Dual microprocessors provide a high level of fail-safe operation combined with fast and reliable performance. The master microprocessor performs high-speed digital sampling and signal processing calculations whilst the slave microprocessor handles various sensor data, performs communications, and self-diagnostics and provides interface versatility and additional memory for storing event log and FirePic™ data. The FS20X detector has a detection range over 60 m (200 feet) (very high sensitivity setting) for the detection of a 0.1m2 (one square foot) Heptane reference fire and has a cone of vision greater in volumetric coverage than most UV/IR detectors. This means fewer detectors can be used as compared to other manufacturers’ detectors.
The FS20 detector using advanced patented algorithms for signal processing and fire and flame analysis is designed to alarm to all types of fires in all industrial environmental conditions. If the detector’s UV signal is degraded due to heavy smoke or a contaminated lens, the FS20X’s patented WideBand IR™, Near Band IR and Visible sensors will still alarm to fire, albeit at a reduced sensitivity and slower response time.

FS20X Plus builds on the FS24X Plus 3IR flame detector by adding UV, enabling detection of a more diverse fuel list, including hydrocarbon, nonhydrocarbon, and hydrogen fires and at greater distances, while simultaneously further reducing spurious alarms. Performance certified to FM3260 and EN54-10 and SIL2 certified to EN61508.
The FS20X Plus comes standard with HART® over the 4-20 mA analogue output. The relays for Alarm, Auxiliary, and Fault are included and may be configured as normally open or normally closed, latching or non-latching. The FS20X Plus features a multi-colored, highly visible LED halo to indicate status locally, eliminating the need for an additional device. The FS20X is for replacement applications.
