F-Guard IR3 H2-HD

F-Guard IR3 H2-HD

The Gastech F-Guard-lR3-H2-HD flame detector provides ultra-fast response, high performance and reliable detec­tion of hydrogen (H2) fires

List of Benefits

  • High immunity to false alarm
  • Ultra-fast detection mode detection within 40 milliseconds for Hydrogen fireballs or explosions
  • Hydrogen flame detection
  • High sensitivity -up to 100 ft.(30m)
  • 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
  • Window heater to avoid condensation and icing
  • Tilt mounting bracket can be connected either above or below the detector.

 
The de­tector addresses slow growing fires as well as fast eruptions of fire using improved IR3 technology. The detector operates in all weather and light con­ditions. In addition, 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). This allows the rescue team to be aware of the exact situation before entering the hazard­ous area. The detector automatically records video of fire event (1 minute pre- and up to 3 minutes post-alarm initiation). These features, along with the built-in event logger, provide ad­ditional means to study the cause and development of fire events
