TheTUN‐38ExHeatDetectorisdesignedfordetectionoffirehazardorfireappearance
warninginclosedrooms,whereduringthefirstphaseoffireanoccurrenceoftemperature
risemaybeobserved,orwhere–duetovariousreasons–temperaturemayexceedtheset
firedangerlevel.
Itisprovidedforworkingtogetherinfiredetectinglineswithcontrolpanelsmanufacturedby
POLON‐ALFAorbyotherproducersthatobtainedPOLON‐ALFA’scompatibilityconfirmation.
Thedetector’soperationaltemperatureisbetween‐25°Cand+50°CforA1classand+65°CforB

Thedetectorcasingismadeofblackcolourplastic.Inordertoremoveelectrostaticcharge,low
surfaceresistancematerialisutilised.Thethermistorisprotectedwithaspeciallyshapedcoverthat
ensuresproperdirectionalcharacteristics.Jointstoconnectdetectinglinecablesandcrampstoset

6PRINCIPLESOFOPERATION
TheTUN‐38Exheatdetectorreactstoariseoftemperatureoccurringduringinitialphaseoffire.
Thedetectoroperatesasafixedtemperaturedetectorafterexceedingitsset‐offoperation
threshold,accordingtoitsgivenclass.Itoperatesalsoasarate‐of‐riseheatdetector‐whentherapid
riseoftemperatureexceedstheleveldeterminedforthedetector,accordingtoitsgivenclass,the
electroniccircuittransmitsawarningsignaltothemastercontrolpanel.Thesignalmayalsoresult
fromthethermistordamage/malfunction.
ThedetectorisprovidedwithasignallingLEDdiodethatshinesinalarmmode.Theindicatorenables
fastlocalisationoftheactivateddetectorandishelpfulinperiodicdetector’sinspections.Incasethe
detectorisinstalledinahardtoreachspace,anadditionalopticalalarmsignalcanbeobtainedby
connectingtheWZ‐31alarminanaccessibleandvisibleplace.
