40/40M Flame Detector

The 40/40M Multi IR Flame Detector is specifically designed for detection of hydrocarbon and hydrogen flames. It detects hydrocarbon-based fuel and gas fires at long distances with the highest immunity to false alarms. The 40/40M IR3 can detect a gasoline pan fire at 215’ (65m) or a hydrogen flame at 100’ (30m) in less than 5 seconds.

List of Benefits

  • Multi Spectrum Design - for long distance detection of hydrocarbons and hydrogen
  • Sensitivity Selection - to ensure no zone crossover detection
  • Automatic and Manual Built-In-Test (BIT) - to assure
  • continued reliable operation
  • Heated window - for operation in harsh weather conditions (snow, ice, condensation)


The 40/40 Series is the most durable and weather resistant range of flame detectors currently on the market. Its new features include a heated window, to eliminate condensation and icing; HART capabilities, for digital communications; lower power requirements, and a compact, lighter design.

Due to increased reliability, the 40/40 Series warranty period has been extended to 5 years and approved to IEC 61508 Safety Integrity requirements of SIL2.
