Space Age Electronics D171 | 1IR+UV Multi-Spectrum Flame Detector

The D171 1IR+UV Multi-Spectrum Flame Detector is the most advanced optical flame detector designed and optimized to respond to hydrocarbon based fires while rejecting false alarm sources. The D171 model senses UV radiation in the ultraviolet spectrum and infrared radiation in one discrete band of the IR spectrum for detecting fires. Flame response and false source rejection for the D171 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 fires at distances of 100+ feet, all while rejecting false sources.

The D171 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 is supplied with Alarm / Auxiliary / Fault relays, 4-20 mA analog and RS485 outputs. The detector can store 200 events and 6 FireGraphs in its FRAM memory.
