312.5.6 Relay CircuitsSection 8.8Fault Output.Relay 1 is arranged for failsafe operation as standard.The MxPro 5 Series are equipped with two relayoutputs. These are normally programmed toactivate on Fault and Fire Alarm conditionsrespectively.Each output is unsupervised with volt-freechangeover contacts rated at 30V AC/DC,1 Ampere, resistive.An Optional plug-in 2-Way relay card is available ifadditional relays are required (Relays 3 & 4).Optional peripheral bus relays cards are alsoavailable.NCCOMNONCNOCOMRELAY 1 RELAY 2Base card connectionsThe Relay outputs can be used, instead of the Routing Interface Card, to provide non-monitored fireand fault routing outputs to appropriate routing equipment.In this case, the panel will not indicate transmission path failures to the routing equipment – this featuremust be incorporated into the routing equipment itself. [Not fully EN54-2 compliant].2.5.7 Auxiliary Supply OutputThe MxPro 5 Series are equipped with an auxiliary24V DC, 500mA power supply output.This can be used for powering ancillary equipmentand must only be used for powering localised /internal equipment.BA0V+24VSWCOMAUX SWITCHPBUSBase Card connections2.5.8 Isolated Peripheral Bus InterfaceThe isolated bus interface is used to connect localperipheral equipment located internal to the panelor located within 10m of the panel.The terminal block on the MxPro 5 Series basecard is shown opposite. Connect the cable from 'A'to 'A' and from 'B' to 'B'. Equipment is connectedvia a daisy chain.External connections should be made using firerated cable or run in rigid metal conduit betweenenclosures.BA0V+24VSWCOMAUX SWITCHPBUS Base Card connectionsPeripheral Bus modules must beconfigured using the PC ToolPanel Base CardTBB A B ATBB A B ATBB A B ATo External ModulesLast Module – FITEOL Jumper to INPeripheral Module Peripheral Module Peripheral ModuleA BPPCCOONNLLYYwww.acornfiresecurity.comwww.acornfiresecurity.com
