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

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.
