Description
The D381 and D383 Multi-Spectrum Flame Detectors are the most advanced optical flame detectors designed to respond to both hydrocarbon and non-hydrocarbon fires while rejecting false alarm sources. The D38X detectors sense UV radiation in the ultraviolet spectrum and infrared radiation in 3 discrete bands of the IR spectrum for detecting fires. Flame response and false source rejection for the D38X models is accomplished by utilizing the Convolution Method and Advanced DSP (Digital Signal Processing) in conjunction with hard coded algorithms identifying specific wavelengths of energy. The detectors are able to respond to hydrocarbon and non-hydrocarbon fires at a distance of 80+ feet, all while rejecting false sources.
