he Detectors Inc. D371 3IR +UV Multi-Spectrum Fire & Flame Detector represents a new generation of optical fire & flame detector designed and optimized to respond to both the Hydrocarbon and Non-Hydrocarbon based fires while rejecting False Alarm Sources. The Protector D371 senses UV radiation in the Ultraviolet spectrum and Infrared radiation in 3 discrete bands of IR Spectrum for detecting fires.
Flame response and false source rejection for the detector is accomplished by utilizing the Convolution Method and Advanced DSP (Digital Signal Processing).
The D371 is a stand-alone fire & flame detector in a watertight NEMA 4X (IP66/67) and explosion-proof Stainless Steel enclosure designed for indoor/outdoor Class I, Div. 1 (Zone 1) Installations. The detector features an automatic self-test for continuously checking the detector’s optical path integrity while monitoring the electronics to ensure utmost reliable operation and fault reporting.
