The Gastech F-Guard-UV-IR HD flame de­tector offers extremely reliable and quick detection of fires and explosions.

List of Benefits

  • High immunity to false alarm
  • Ultra-fast detection mode detection within 5 milliseconds for fireballs or explosions
  • Hydrogen and Hydrocarbons flame detection
  • High sensitivity -up to 100 ft. (30m) for a 1 ft2 (0.1m2) n-heptane pan fire
  • 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
  • Ethernet communication -in addition to the standard methods, such as 4-20mA and Modbus
  • Built-in-Test (BIT) -Automatic and manual internal self-test of window cleanliness and the overall operation of the detector (for both IR and UV channels)
  • Window heater to avoid condensation and icing
  • Tilt mounting bracket can be connected either above or below the detector

The Gastech F-Guard-UV-IR HD flame de­tector provides ultra-fast esponse, high performance and reliable detection of a large variety of fires including hydro­carbon fires (visible and nonvisible), as well as Hydrogen fires. The detector addresses slow growing fires as well as fast eruptions of fire us­ing improved UV-IR technology. The detector operates in all weather and light conditions. The detector provides high-definition (HD) video output of the monitored area with clear imaging of a fire event and of personnel at distances 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 UV-IR flame detection and you have a very powerful safety tool to protect your per­sonnel, plant and process. personnel, plant and process.
