SIL2 IR3 Flame Detection


Designed for hazardous industries where fast fire detection is critical and nuisance alarms are not an option!

The MICROPACK FDS303 is an explosion-proof multi-spectrum IR flame detector. The device delivers superior performance, responding to hydrocarbon liquid fuel and gas fires at long distances.

The FDS303 has been tested by Factory Mutual to detect a hydrocarbon fuel pan fire at 60 m (~ 200 feet) in 5 seconds.


The FDS303 complements the FDS301 and FDS300 Visual Flame Detectors by delivering superior performance in the detection of hydrocarbon fires which are not detectable in the visible spectrum. The FDS303 utilises the latest IR flame detection algorithms to ensure maximum false alarm immunity.


Typical applications include:

  • On/Offshore Oil and Gas Processing Facilities
  • Refineries
  • Petrochemical Plants
  • Chemical Facilities
  • Pharmaceutical
  • Aircraft Hangars
  • Road Tunnels
  • Power Generation
  • Tank Farms
  • Road & Rail Loading Racks
  • LNG / LPG
  • Warehouses/ Storage Areas
  • Waste Recycling/ Biomass Plants
  • Printing Industry

Features and Benefits

  • Multi-spectrum IR design delivers long detection distances and enhanced false alarm immunity
  • Continuous optical test, without a reflector, verifies operation and improves device up-time
  • Microprocessor controlled heated optics, maintains operation in harsh weather conditions (snow, ice, condensation)
  • International hazardous area approvals, FM / ATEX / IEC Ex
  • Certified performance testing to multiple fuels to FM 3260 and EN 54-10
  • Adjustable sensitivity levels, for application flexibility and to ensure detectors do not cross vote
  • External testing with a long-range flame simulator minimises the need for scaffolding
  • Easy integration using industry standard outputs: Alarm and Fault Relays; 0-20mA; HART®, as standard
  • Certified SIL 2 capable
  • 5 year warranty
