Although loudspeakersmay mimic alarm tones, they also give alert tonesand other progress tones when setting andunsetting the alarm system.Output on KEY-KPZ01Figure shows the wiring required to connect anoutput the output terminal on the KEY-KPZ01.RS4850V 12V A B OP1K0 Ohm ResistorLED (Light Emitting Diode)Figure 50 KEY-KPZ01 Output WiringStep 8. Connect the InternalCommunicatorThe control unit has an internal communicator onits main PCB. This is an auto-dialling modem.If necessary, a standalone communication devicecan be connected through a wiring harness tointerface pins on the main PCB (this is known as aplug-by communicator, see page 28).The communicator can be used for:• Transmitting alarm signals to alarm receivingequipment at a central monitoring stationusing Scancom Fast Format, Scancom SIA(Security Industry Association) or Contact ID.• Connecting to a PC based at a remoteengineering centre. Using Eaton’s SecurityBusiness Downloader software, the remotePC can upload and download systemparameters (including the event log anddiagnostics), set and unset the alarm system,and carry out other special functions.Telephone LineIdeally, the internal communicator should beconnected to an ex-directory line used exclusivelyfor alarm communications.Line Monitoring for the Internal CommunicatorThe control unit provides a line monitoringfunction to check that a telephone line connecteddirectly to the control unit is working, and toindicate a line failure if it is not. While enabled,this function continually checks the line voltage toensure that the line is connected. If it detects afailure, the system gives the Line Fault Responseselected in the Installer Menu.Test CallsThe control unit can be programmed to make testreport calls to an ARC. "Static" test calls can beprogrammed to occur at set times or intervals."Dynamic" test calls occur 24 hours after the lastcall made by the unit. See the Menvier40/100/300Engineering Guide for details on how to programthese functions.Statutory InformationApplicationsThe built-in communicator is suitable forconnection to the following types of networks:(a) Direct exchange lines (PSTN) supportingDTMF (tone) dialling.(b) PABX exchanges (with or without secondaryproceed indication).Note: The built-in communicator is not suitable forconnection as an extension to a pay-phone or to 1+ 1 carrier systems.ApprovalThe built-in communicator is manufactured tomeet all European Economic Areatelecommunication networks requirements.However, due to differences between theindividual PSTNs provided in different countries,the approval does not, of itself, give anunconditional assurance of successful operationon every PSTN network termination point.The built-in communicator has been approved forthe following usage:(a) Automatic call initialisation.(b) Operation in absence of indication to proceed.(c) Automatic dialling.(d) Modem.(e) Serial connection.(f) Multiple repeat attempts.(g) Line status monitoring.Usage other than approved usage or failure tocomply with the installation and programminginstructions may invalidate any approval given tothe apparatus if, as a result, the apparatus ceasesto comply with the standards against whichapproval was granted. Note the approval label onthe main PCB.In the event of problems you should contact yourequipment supplier in the first instance.Ringer Equivalence NumberThe Ringer Equivalence Number (REN) of thebuilt-in communicator is 1. As a guide to thenumber of items that can be simultaneouslyconnected to an exclusive line, the sum of theREN values should not exceed 4. A standardtelephone (as provided, for example, by BT in theUK) has a REN value of 1.
