D371 3IR+UV Multi-Spectrum Flame Detector

The D371 Multi-Spectrum Flame Detector is the most advanced optical flame detector designed to respond to both hydrocarbon and non-hydrocarbon fires while rejecting false alarm sources. The D371 detector senses 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 D371 model 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 detector is able to respond to hydrocarbon and non-hydrocarbon fires at a distance of 200+ feet, all while rejecting false sources.

The D371 is a stand-alone fire & flame detector in a watertight NEMA 4 & 4X (IP66,67) and explosion-proof stainless steel enclosure designed for indoor/outdoor Class 1, Div. 1 (Zone 1) installations.

The detectors are supplied with Alarm / Auxiliary / Fault relays, 0-20 mA analog and RS485 outputs. They can store 200 events and 6 FireGraphs in their FRMA memory.
