SystemComponents TheZONESCAN800systemconsistsofthefollowingcomponents:
Radiologgers SystemCommunicationLink(ZS820Bluetooth) Communicationcable(Serial/RS232C) Mobilecomputer(laptop)withZONESCAN800software 1.2. Radiologgers The radio loggers continuously monitor and analyze noise characteristics. The loggers need no maintenance. Depending on the setting of radio operation period and how often the functions CorrelationandRemotelistening(seeLoggerState)areused,batterylifetimenormallyexceeds5 years.Batterymaybereplacedbyauthorizedpersonnelonly. 1.3. SystemCommunicationLink The System Communication Link (abbreviated: CommLink) serves as an interface for radio communication between computer and the loggers. It is connected to the computers serial interface via the Communication Cable. When connected to the computer the System Communication Link will be automatically detected as soon as the ZONESCAN 800 software is started. It is switched off either by exiting the software or disconnecting it from the computer. Later version CommLinks have a push on/off button. Depending on the surrounding conditions, radiotransmissiontotheloggersispossibleuptoseveralhundredmetres. 2. ZONESCAN800software TheZONESCANsoftwareprovidesavarietyoffunctions:

The following section explains how the sampling process works. The tables depict when the logger takes a noise sample and what the sample is caused by, e.g a passing car or leak. Traffic &
Consumption noise should be ignored. A large number of samples at the quietest level, indicate a consistant sound that could be a leak which never stops. The Leak is the closest to the loudest, quietest noise.

Logger synchronization allows programming of the loggers by transferringthecorrespondingloggersetupdatatotheloggerandreceivingstoredmeasurementsfromthe loggers. Inwizardmodetheuserwillbeguidedthroughthesynchronizationsetup. Explanationofoptions:
Synchronize only reachable loggers (in case only few loggers are in transmission range, "driveby operation"): During synchronization the System Communication Link will search for the next reachable logger. This option should be used during normal operation when loggers are deployed throughout the distributionnetworkandonlyfewloggersareintransmissionrange.Iftoomanyloggerscanbereachedat thesametime,theSystemCommunicationsLinkwon'tbeabletoestablishradiotransmissiontoallloggers. Seealsonotebelow. Synchronizeaccordingtologgerlist(incasemanyorallloggersareintransmissionrange):Thismodeshould be used when many loggers are at the same place e.g. for initial programming or testing of the loggers. Duringsynchronizationthesoftwarewilltrytoconnecttheloggersexactlyinthesameorderasshowninthe loggers list of the main window. This mode is not suited for collecting data of deployed loggers as the synchronizationprocessfollowsastricttimecourse. Get sound signal for correlation: Get recorded sound signal. Sound signal is only available if logger was preparedtorecordsoundsignalduringaprevioussynchronization. Afterselectingtheoptions,synchronizationprocesswillbestartedautomatically.Accordingtotheselected orderofsynchronization,theSystemCommunicationLinkwillsearchforthenextreachableloggerorthe nextloggeroftheloggerlist.Oncealoggerisrecognized,datawillbetransferredfromandtotheloggeras specifiedbythesynchronizationoptions.Successandfailuremessagesaswellaswarningmessageswillbe displayedinthestatuspaneloftheMainWindow.Ifaudiooutputisswitchedon,therewillalsobeaudio messages. After successful synchronizing a logger in Reachable loggers mode the logger can't be re synchronizedthenext5minutes. ImportantNotes(pleaseread):
PleasecheckwhethertheselectedorderofSynchronizationoptionisadaptedtothetransmissionsituation. Synchronizeonlyreachableloggerswon'tworkproperlywithtoomanyloggersandSynchronizeaccording tologgerlistwon'tworkproperlywithdeployedloggers.Incasesynchronizationofasingleloggerisdesired pleaseusetheSynchronizecommandaccessedfromtheLoggerStatewindow.
