SharpEyeTM IR3 Flame Detector User Guide 1.3 1.4 Features and Benefits Detection Range: Up to 215 ft. (65m) for a 1 ft2 (0.1m2) n-heptane fire. Ultra High Immunity to False Alarms: See Table 4 on page 11. Advanced Digital Processing of the Dynamic Characteristics of Fire: Flickering, threshold correlation and ratio. Multi IR Channels: Between 2-5 microns. Field Programmable Sensitivity: Four ranges to avoid zone crossover.
TM 40/40I, Rev (6) July 2013 The detector’s principle of operation is based on patented IR3 technology. This technology identifies the unique spectral signature that hot CO 2 has in the infrared (IR), namely a peak of the intensity at wavelengths 4.2 to 4.7µ. The original IR3 technique (such as implemented in the SharpEye 20/20I flame detector) utilizes three infrared sensors, each sensitive to its own wavelength range. The first sensor is sensitive to wavelengths within the emission peak of hot CO2.
