1.0 Introduction
1.1 ProductDescription
TheDetectorsInc.modelD381isanewgenerationof
general‐purposeandmediumrangeMulti‐Spectrum
3IR + UV flame detector designed for detection of
firesinmultitudeofindoorandoutdoorapplications.
The Model D381 senses the Ultraviolet radiation in
UV spectrum and Infrared radiation in 3 discrete
bandsofIRintherangeof2‐5microns.Thedetector
will respond to Hydrocarbon and non‐Hydrocarbon
basedfireswithin3seconds.
The Model D381 is a stand‐alone flame detector in
watertight NEMA 4 (IP67) and explosion‐proof
aluminum enclosure designed for Class I, Division 2
(Zone 2) installations. The detector offers multiple
outputs including two fire alarm relays, 4‐20 mA
analogandRS485ModBusRTU.
Thedetectorcanbeusedasastand‐alonedeviceor
canbeinterfacedwithanyapprovedfirealarmpanel,
controlsystem,orPLC.TheD381detectorfeatures
anAutomaticSelf‐Testforcontinuously monitoring its sensors and electronics. Additionally, the detector is
equippedwithOptiRadarfeaturethatcontinuouslychecksthedetector’sopticalpathintegrityandthewindow
blockagebyexternalobjects.ThisfeaturewillinitiateaFaultsignalifanyobjectisblockingtheviewingwindow
within1”ofdetector.
