FlameGard® 5 UV/IR-H2 Flame Detector

The MSA FlameGard® 5 UV/IR-H2 Flame Detector is an ultraviolet/infrared flame detector designed to detect unwanted hydrogen fires.

The FlameGard® 5 UV/IR-H2 Detector detects fires by monitoring in both the ultraviolet and infrared (UV & IR) spectral ranges, making it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation.

Other features of the FlameGard® 5 UV/IR-H2 Flame Detector include three alarm/fault relays, and an RS-485 serial output with Modbus RTU protocol for linking up to 128 detectors in series or 247 with repeaters. The RS-485 and HART outputs provide status, alarm, fault and other information for operation, troubleshooting or programming of the units. HART enables this feature without the need for rewiring.

The continuous optical path monitoring (COPM) self-test feature checks both the optical path integrity (window cleanliness) and the detector's electronic circuitry once every minute.

Features & Benefits:

  • Wide field of view enables greater fire detection coverage
  • Event logging stores fault and alarm history
  • 4-20 mA stepped output is the industry standard for remote alarm and fault indication Modbus and HART user interface provides complete status and control capability in the control room
  • Wide operating temperature range permits operation at a higher ambient temperature
  • Continuous Optical Path Monitoring (COPM) checks both the optical path integrity and the detector’s electronic circuitry once every minute
  • Three SPDT high-current programmable relay outputs provide both immediate and time-delayed relay outputs for alarm, warning and fault conditions
