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.
