The devices of the 40/40 series operate under the harshest environmental conditions and are standalone, independent units designed for direct connection to control and alarm systems or automatic fire suppression systems.

40/40I Triple IR (IR3) Flame Detector

The 40/40I Triple IR (IR3) flame detector detects fuel and gas fires at long distances with the highest immunity to false alarms. The 40/40I IR3 can detect a 0.1 m² (1 ft²) gasoline/heptane pan fire at a distance of 65 m (215 ft) in less than 5 seconds.

40/40M Multi IR Flame Detector

The 40/40M Multi IR flame detector has been specifically designed for the detection of hydrocarbon and hydrogen flames. It detects hydrocarbon-based fuel and gas fires at long distances with the highest immunity to false alarms.

40/40 Series UV/IR Flame Detectors

The UV/IR flame detectors of the 40/40 series are available in two versions:

• The Model 40/40L (& LB) detects hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires.
• Model 40/40L4 (& L4B) is identical to the 40/40L, except that the IR sensor operates at a wavelength of 4.5 µm and is suitable only for hydrocarbon-based fires.

40/40UV Flame Detector

The 40/40UV flame detector is the most durable and weather-resistant UV flame detector currently available on the market.

40/40R Single IR Flame Detector

The 40/40R Single IR flame detector detects hydrocarbon-based fuel and gas fires using advanced flame analysis technology.

20/20 Range

The 20/20 range includes Mini IR3 and Mini UV/IR detectors offering a cost-effective, energy-efficient, and compact design in a general-purpose format (without hazardous area approval). The 20/20MI IR3 is also available as an intrinsically safe ATEX-certified detector.
