37 Amended: Jan 2014The network can be wired as either a Loop or a Radial. If Booster devices are used the system mustbe run as a RadialThe maximum cable length before Boosters are used is 1000m.The Terminator resistors are fitted across the network to smooth out the signal. The network requires51ohms across pos & neg when checked at any card on the network, This can be achieved by cuttingoff or soldering on resistors as required. (See Figs 32, 34, 35, 36 & 37)On the later version network card this process has been improved by selecting the switches providedon the PCB for loop topology or radial (bus) and terminator in or out.NOTE Connection details on the terminal block are not polarity sensitive.Cable TypesThe recommended cable for the network connection between panels is an enhanced cablemanufactured by Draka Cables (Pt No 910234). Screen continuity must be maintained throughout theentire network circuit including each junction point.The screen should only be earthed at the connection point at the first panel and not at any other point.The screen or drain wire of the network cable should not be considered as a safety earth andtherefore should not be connected to the terminals marked with the earth symbol, except at the panel,and should not be insulated with green/yellow sleeving.Where the network passes between buildings, screen continuity should not be maintained frombuilding to building. A Booster device must however be used irrespective of cable length and shouldbe fitted at a suitable point in the link between buildings. The screen should be connected to the earthof one panel in each building.The L-Switch Booster is made by a firm called Loytec, and works on a supply voltage of 9-35 v DC.This means that the Easicheck or DF6000 panel external 24v output can power this device.The Booster has two modes of operation ‘Smart Switch mode’ and ‘Configured Router’, for allapplications we use the former mode. In this mode the device automatically detects the bit-rates ofthe connected channel, copies the information detected on the network and forwards it to the nextnetwork card.ConfigurationsNetwork configuration without Boosters - RadialFig 34
