ZonedNetworkReceivershelptheonsiteManagertoidentifywhichareaofthe
buildingapendantalarmhascomefrom.

169MHzZonedNetworkReceiverswereintroducedinSeptember2011andcan
onlybeusedwithAdventxtControllerfirmwareV2.03aonwards.

Fullradiocoveragemustfirstbeachieved
usingstandardZXT325Network
ReceiverswithW062501/2WaveAerials,thenalimitednumberofZXT326Zoned
NetworkReceiverscanbedeployedaroundthesitetogivelocalisedradio
coverage.

IMPORTANT:themaximumnumberofZonedNetworkReceiverspersiteis12,for
exampleyoucouldinstallthefollowingmaximumcombinations;4standard+12
zoned,or6standard+10zoned,or8standard+8zonedetc.

WhenapendantisactivatedthezonewiththestrongestRadioSignalStrength (RSSI)
willbeidentifiedinthealarmmessage.IfthependantisnotwithinrangeofanyZoned
Receiverthenthecallwillstillbepicked‐upbytheStandardReceiversandreported
withoutanyzoneinformation.

ATTENUATOR & AERIAL

Togivethereducedrange,ZonedNetworkReceiversaresuppliedwitha10dBBNCAttenuatorandaHelicalStubAerial.
SimplyplugtheBNCAttenuatorbetweentheNetworkReceiverandtheAerial.These2partsMUSTBE
fittedtoZoned
NetworkReceivers‐DONOT
fit1/2WaveAerials(W06250).

CONNECTION

ZonedNetworkReceiversrequireapoweranddatafromtheAdventxtsystemnetworkusinga2pairCW1308cable.

INSTALLATION

ZonedNetworkReceiversshouldbesitedinadrysecurearea,theyareNOTsuitableforoutdoorlocations.Choose
locationscentraltothezoneyouintendcovering.TryandspacetheReceiverstominimiseradiooverlapbetween
neighbouringzones.SeethefollowingpagefordetailsoftestingandRSSI attenuation.

ID SETTING

DILswitches1to4areusedtosetauniqueIDoneachZonedNetworkReceiver,DILswitches5to8arenotused.ID’smust
followonsequentiallyaftertheStandardNetworkReceivers.Seetableonpreviouspage.

PROGRAMMING

TheID’softheZonedNetworkReceiversmustbesetinthe“ZoningSetup”programming.
ThetotalnumberofStandard+ZonedNetworkReceiversmustbesetinthe“GeneralSetup”.
SeetheAdventxtProgrammingManual(TynetecDocNo.FM0411issue“F”onwards).
