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  m)  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 occur 1  Locate detectors at the corners of an area or module 1  Employ CAD tools to optimize area coverage at the design stage 1  Install detectors on the perimeter of equipment under detection, with unobstructed lines of sight and on rigid mounting points 2  Determine maximum distance from detector to item or area to be covered after considering fire size, fuel type, and desensitizing effects from environmental conditions 3 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.
