Flame Detection System

40/40 UV/IR Flame Detector

Spectrex offers two versions of the new 40/40 Series UV/IR Flame Detectors: Model 40/40L (& LB) and Model 40/40L4 (& L4B). The UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum.

40/40R Flame Detector

The new 40/40R Single IR Flame Detector detects hydrocarbon-based fuel and gas fires using advanced flame analysis tools. The detector provides early warning of flaming fires working at 4.5 μm for maximum sensitivity, and immunity to false alarms from IR sources such as sunlight and IR projectors.

40/40I Flame Detector

The new 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 1ft2 (0.1m2) gasoline pan fire at 215 ft (65m) in less than 5 seconds.

40/40M Flame Detector

The new 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.

Flame Simulators

Spectrex Long-Range Flame Simulators are specifically designed for testing the various SharpEye Optical Flame Detectors. To comply with local standards and jurisdiction, "end-toend" loop testing of Fire Protection Alarm Systems, including detectors, should be performed periodically.


The SharpEye Model 20/20SI is a new version of the Triple IR Spectrum Flame Detector designed to provide maximum fire protection. The optical sensors and filters have been carefully selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire, and the lowest degree of matching to non-fire stimuli.


The SharpEye UV/IR High- Speed Optical Flame Detector (20/20F) is the new derivative of our wellknown military detector used in Armored Vehicle Explosion Suppression System (The SAFE System). This flame detector is designed to meet two important requirements: fast response time (less than 5 milliseconds) & high reliability (immune to false alarms)


The SharpEye UV/IR Optical Flame Detectors 20/20L and 20/20LB (which includes a BIT function) are an improved version of the well-proven Spectrex Ultra Violet/Infra Red (UV/IR) optical flame detectors featuring modern microprocessors and detection algorithms that provide excellent detection sensitivity combined with enhanced immunity to false alarms.
