The Fire Sentry 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
Electro-Optical Flame detectors.
Based on the foundation of the highly successful and reliable Fire Sentry
SS4 detector, the Fire Sentry FS20X detector represents a quantum leap in
integrating Infrared and Ultraviolet sensing technologies. The Fire Sentry FS20X
is a Multi-Spectrum and UV/Dual IR/VIS fire and flame detector with a proven
UV solar-blind sensor. The Fire Sentry 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. Also, these old technology UV/IR
detectors will not alarm to any fire if they are installed behind ordinary
window glass.
The Fire Sentry FS20X detector uses 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
Fire Sentry FS20X’s patented* WideBand IRTM, Near Band IR and Visible
sensors will still alarm to fire but at a reduced sensitivity and slower
response time.
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;
while the slave microprocessor handles various sensor data, performs
communications, self-diagnostics and provides interface versatility; and
additional memory for storing Event Log and FirePicTM data.
The Fire Sentry FS20X detector has a detection range in excess of 200
feet (very high sensitivity setting) for the detection of a 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.
