Model D381 UV/IR/IR/IR Fire & Flame Detector

The Detectors Inc. Model D381 UV/IR/IR/IR Multi-Spectrum Flame Detector is a new generation flame detectors designed multitude of general purpose applications requiring an economical and reliable fire detection and monitoring for detecting fires. The Model D381 senses Ultraviolet radiation in the UV spectrum and Infrared radiation in 3 discrete bands of IR spectrum for detecting fires.
The Model D381 flame response and false alarm source rejection is accomplished by utilizing a the Convolution Method and Advanced DSP (Digital Signal Processing) The detector will respond to a 1 ft x 1 ft. n-Heptane or IPA fire from 60 feet within 3 seconds.
The Model D381 is a stand-alone fire & flame detector in watertight NEMA 4 (IP66) and explosion-proof Aluminum enclosure designed for Class I, Div. 2 (Zone 2) Installations. The Detector features automatic self-test for continuously checking the optical path integrity while monitoring the electronics to ensure utmost reliable operation and fault reporting.
