F-Guard IR3-HD

F-Guard IR3-HD

The Gastech F-Guard IR3-HD will detect fires and explosions extremely fast allowing preventative action to be initiated rapidly and thus minimizing the consequences.

List of Benefits

  • High immunity to false alarm
  • Extreme sensitivity -up to 30m or a 1 ft2 (0.1m2) n-heptane pan fire=High immunity to false alarm
  • Ultra-fast detection mode -detection within 40 milliseconds for fireballs or explosion
  • 1.2 seconds detection time -for 1 ft2 (0.1m2) n-heptane pan fire at up to 50 ft. (15m) distance
  • HD video output with Automatic HD video recording of fire events. Data/Event logger: Alarms, faults and other relevant events are logged to non-volatile memory
  • Built-in-Test (BIT) -Automatic and manual self-test of window cleanliness and the overall operation of the detector
  • Window heater to avoid condensation and icing
  • Tilt mounting bracket can be connected either above or below the detector.

 
The Gastech F-Guard-lR3-HD flame detector provides ultra-fast response, high performance and reliable detec­tion of all types of hydrocarbon fires (visible and non-visible). The detector addresses slow growing fires as well as fast eruption of fire using improved triple IR (IR3) technology. It operates in all weather and light conditions with highest immunity to false alarms. The detector provides high-definition video output with clear imaging of fire event at up to 100 ft. (30m), allowing rescuers to know the exact situation before entering the hazardous area. It will automatically record a video of a fire event (1 min pre-alarm/ up to 3 min post-alarm). Add to that, the integral HD quality vid­eo, with event recording, on top of the proven superior capabilities of Triple IR (IR3) flame detection and you have a very powerful safety tool to protect your personnel, plant and process.
