Core Performance & Features
Multi-Spectrum Triple IR Detection: Combines four infrared sensors and solid-state quantum sensors for superior flame recognition.
High-Speed Digital Sampling: Powered by an advanced microprocessor that executes fast digital sampling to enhance detection speed while reducing false alarms.
Wideband IR Technology: Utilizes 4.3-micron IR sensors exceptionally sensitive to hydrocarbon flames, even through dense smoke, dust, or vapor.
Patented FirePic™ Data Storage: Records pre-fire data for detailed event examination and historical performance review.
Real-Time Graphing (RTG): Enables real-time output graphing for maintenance diagnostics and system optimization.
Self-Test Functionality: Automatically monitors sensor health, window lens clarity, and internal diagnostics to maintain consistent accuracy.
Modular Detector Puck Design: Allows easy replacement and servicing without removing the complete unit.
Industrial Application Scenarios
Designed for hazardous and demanding locations, the Honeywell FS24X-9 Flame Detector is ideal for:
Oil and Gas Facilities: Rapid fire detection for high-risk hydrocarbon fuels.
Chemical Processing Plants: Detecting flames in areas with hazardous vapors and volatile chemicals.
Power Generation: Ensuring safety in turbine enclosures and fuel-handling systems.
Manufacturing Environments: Fire monitoring in flammable storage and heavy production zones.
Offshore Platforms: Withstanding corrosive marine atmospheres and extreme weather.
Installation Guidelines
Mounting Requirements: Surface-mount or install using optional mounting brackets, ensuring a clear, unobstructed field of view toward potential fire sources.
Wiring Instructions: Follow Honeywell’s installation diagram. Use stranded conductors (AWG 12–22) and verify correct polarity.
Address Setting: Configure unique digital addresses using the onboard DIP switches to avoid network duplication.
Final Checks: Inspect all wiring terminations and verify LED indicators to confirm system communication and detector readiness.
