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.
The D371 3IR +UV Multi-Spectrum Fire & Flame Detector (Patent pending) 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).
