  1. FlameGard 5 UV/IR Flame DetectorThe Benefits of HART on Installation and Maintenance of Flame Detectors

  2. Contents • Product Overview • Principle of Operation • Spectral Range for Flame Detection • Field of View • Detector Placement • Wiring • Test Lamp Check • Fault Conditions • HART • Applications • Conclusion

  3. FlameGard 5 UV/IR Flame Detector Description • HART enabled flame detector with ultraviolet and infrared sensors Customer Benefits • Features wide field of view, enhanced false alarm response, COPM, and broad temperature range • Stores time-stamped records of warnings, alarms, and maintenance events • Supports HART communication • Compatible with Emerson Process Management’s AMS Intelligent Device Manager • Better protection against electromagnetic emissions

  4. Principle of Operation Measures the radiant intensity of light and fluctuations of radiant intensity to detect a flame • Monitors spectral range in ultraviolet (185 – 260 nm) and infrared (4.35 mm) • Provides warning when both UV and IR sensors respond to a flame

  5. Spectral Range

  6. Field of View

  7. Detector Placement As with other flame detectors, allocation of the FlameGard 5 UV/IR should be considered carefully: • Place detector so field of view covers areas where fires may occur1 • Locate detectors at the corners of an area or module1 • Employ CAD tools to optimize area coverage at the design stage1 • Install detectors on the perimeter of equipment under detection, with unobstructed lines of sight and on rigid mounting points2 • Determine maximum distance from detector to item or area to be covered after considering fire size, fuel type, and desensitizing effects from environmental conditions3 1 HSE Hazardous Installations Directorate, Offshore Division, “Fire and Explosion Strategy, Issue 1.” 2 “HSSE Fire Protection Design Philosophy,” British Petroleum, Document No. OCC-IPMT-PR-HSSE-00004, Rev 0. 3 “Guidance and Practice for Fire and Gas Detection,” British Petroleum, GP 30-85, 29 January 2003.

  9. Test Lamp Check Test lamp check allows independent verification of detector’s operation Regardless of approach used to activate test mode, each time a FlameGard 5 UV/IR successfully detects the test lamp, it records a time stamp of the event

  10. Fault Conditions Self-diagnostics show specific device failures

  11. HART Configuration available with HART protocol • Provides uniform and consistent communication for all field devices • Continuous, real time diagnostic, process, and maintenance data

  12. Uses of HART and Modbus Asset management and process improvement • Check compliance to maintenance schedule • Coordinate test lamp checks to reduce labor cost • Aggregate maintenance to a control room • Read fault conditions from control room before sending technician to the field

  13. Applications The FlameGard 5 UV/IR is suited for a wide range of applications: • Gas Compressor Stations • Pipelines • Gas Turbine Power Plants • Oil and Gas Terminals • Refineries • Oil and Gas Storage Tanks • Oil and Gas Platforms

  14. Conclusion FlameGard 5 UV/IR Flame Detector offers significant advantages over many detection instruments • Long detection range and wide field of view • Event logging • Digital communication (HART and Modbus) FlameGard 5 UV/IR reduces total cost of ownership • Enhances management of maintenance, faults, and warning and alarm records through HART & Modbus • HART reduces need for new hardwiring

  15. Conclusion HART and Modbus communication allow users to get the full benefit from the FlameGard 5 UV/IR Flame Detector • Real time device diagnostics enable proactive action to avoid process disruptions and unplanned shutdowns • Digital communication ensures that device information can be linked remotely to other digital networks • Advanced diagnostics help increase safety integrity levels • When connected to plant asset management software, digital communication protocols enable greater operations efficiencies
