Honeywell Analytics Fire Sentry FS20X
Multi-Spectrum UV/Dual IR/VIS Fire and
Flame Detector
Agency Listings
General
The Honeywell Analytics 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 reliable Fire Sentry SS4 detector, the
Fire Sentry FS20X detector integrates infrared and ultraviolet
sensing technologies. It 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
Features
• Patented* WideBand IR™ Infrared combined with Ultraviolet
• Detection range greater than 200 ft. 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 and
plug-in terminations for easy field installation
• Two ¾” NPT OR 25mm conduit entries
