FS20X Fire and Flame Detector
MultiSpectrum UV/Dual IR/VIS Fire and Flame Detector
FS20X Detector
The FS20X is the latest generation high technology Multi Spectrum
(UV/Dual IR/VIS) Fire and Flame Detector, which is part of the FSX
family of advanced technology ElectroOptical Flame detectors.
Based on the foundation of the highly successful and reliable SS 4 detector, the FS20X detector represents a quantum
leap in integrating Infrared and Ultraviolet sensing technologies. The FS20X is a MultiSpectrum 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
to 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, self-diagnostics and provides interface versatility and additional memory for
storing event log and FirePic™ data. The FS20X detector has a detection range in excess of 60 m
2
(200 feet) (very high sensitivity setting) for the detection of a 0.1m
(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.
