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

Principle of Operation Measures the radiant intensity of light and fluctuations of radiant intensity to detect a flame q Monitors spectral range in ultraviolet (185 – 260 nm) and infrared (4. 35 mm) q Provides warning when both UV and IR sensors respond to a flame

Spectral Range

Field of View

Detector Placement As with other flame detectors, allocation of the Flame. Gard 5 UV/IR should be considered carefully: q Place detector so field of view covers areas where fires may occur 1 q Locate detectors at the corners of an area or module 1 q Employ CAD tools to optimize area coverage at the design stage 1 q Install detectors on the perimeter of equipment under detection, with unobstructed lines of sight and on rigid mounting points 2 q 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 2 3 HSE Hazardous Installations Directorate, Offshore Division, “Fire and Explosion Strategy, Issue 1. ” “HSSE Fire Protection Design Philosophy, ” British Petroleum, Document No. OCC-IPMT-PR-HSSE-00004, Rev 0. “Guidance and Practice for Fire and Gas Detection, ” British Petroleum, GP 30 -85, 29 January 2003.
