D381 3IR+UV Multi-Spectrum Flame Detector

The D381 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 D38X detectors sense 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 D38X models 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 detectors are able to respond to hydrocarbon and non-hydrocarbon fires at a distance of 80+ feet, all while rejecting false sources.

The D381 detector is designed for a multitude of applications. The detector will respond to a 1 ft. x 1 ft. n-Heptane or IPA fires from 200 feet within approximately 3-5 seconds. The models D38X series are stand-alone fire & flame detectors in watertight NEMA 4 (IP66/67) aluminum enclosures. The detectors feature automatic self-test for continuously checking the optical path integrity while monitoring the electronics to ensure utmost reliable operation and fault reporting.

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.
