The Spectrex 20/20SI is a new version of the Triple IR Spectrum Flame Detector designed to provide maximum fire protection. The optical sensors and filters 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 patented Triple IR (IR3) circuit design scans for oscillating IR radiation (1 to 10 Hz) in the spectral bands ranging from 4.0 to 5.0 microns. This highly advanced detector uses programmable algorithms which check the ratio and correlation of data received by the three sensors. The microprocessor design allows for unique field programmability not found in similar Detectors, making the 20/20SI highly immune to false alarms.
