Owner's Manual

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.
Features
• Patented* WideBand IR™ Infrared combined
with Ultraviolet
• Detection range greater than 200 feet to 1
sq. ft. heptane fire
• Patented* Electronic Frequency Analysis
• Visible Sensor for optimum false
alarm rejection
• Selectable detection sensitivities
• Solar blind 90° full 100% cone-of-vision
• Dual Microprocessors for reliable
performance
• Real-time clock for accurate time dating
of events
• FirePic™ — Up to 6 pre-fire event
data storage
• Event log — Up to 200 events with date and
time stamp
• Built-in RS-485 ModBus Communication
• Built-in non-isolated 4-20 mA analog output
(sink or source)
• Alarm, Fault and Fire Verification relays.
• Automatic Optical Path and Electronic
Self-Test
• Widest operating temperature range
• Patented* Electronics Module for
components protection with plug-in
terminations for easy field installation
• Two ¾” NPT OR 25mm conduit entries
• Low power consumption
• High RFI and EMI immunity
• FM approved
Benefits
• Detects hydrocarbon and non-hydrocarbon
fuel fires in all environmental conditions
• Arc welding immunity
• False alarm rejection for all environmental
conditions
• Minimal maintenance for trouble-free
operation
• PC software and Interface Module (FSIM) for
fault diagnostics real-time graphs (RTGs),
and downloading of FirePics™ and event log
• Suitable for a wide variety of applications
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.
