Viking VSF301 Video Flame Detector

The Viking VSF301 is an explosion-proof visual flame detector. It processes live video images to detect the characteristic properties of flames visually, by means of its FM- and SIL 2-certified flame detection algorithms and onboard digital signal processing (DSP). It is the safest and most advanced flame detector on the market today.


• Comprehensive design and support services provided by Viking Integrated Safety
• Intelligent video flame detection (iVFD) principle ensures maximum false alarm immunity and eliminates sensitivity from modulated sunlight
and black body heat
• Operates with or without color video output
• On-board recording of pre- and post-fire alarms
• Continuous optical test, without a reflector, verifies operation and improves device up-time
• Microprocessor controlled heated-optics maintains operation in harsh weather conditions (snow, ice, condensation)
• International hazardous area approvals: FM / ATEX / IEC Ex
• Certified performance testing to multiple fuels: FM 3260 / EN 54-10
• Spatially aware—single sensitivity detection
• External testing with a long-range flame simulator minimizes the need for scaffolding
• Easy integration using industry-standard outputs: Alarm and Fault Relays (0–20mA), HART®, as standard
• Certified SIL 2 capable
• Worldwide marine approvals
