Man-1111_SigmaXT+_Coincidence_Unit_18 Page 15 of 368.4 Connecting to Sigma CP fire panel serial busThe ECU may be activated by selected zones from the serial bus of a Sigma CP conventional fire panel if required.The zones that will activate the ECU are selected as described in section 14.3.The terminals marked CIE SERIAL on the lower terminal block of the ECU should be connected to the terminalsmarked RS485 on the Sigma CP fire panel.It is important that the polarity is carefully observed and that + is connected to + and – is connected to –The RS485 terminating jumper LK1 must be fitted to the last ECU on the serial bus. This jumper is fitted asstandard on all ECUs so will need to be removed from all ECUs except the last one connected to the RS485 bus.To remove link LK1 from an ECU, undo the two screws holding the plate in place and lift the plate away from thebox. Locate LK1 as shown below and pull it off of the pins.Refit the plate and screws.Leave link LK1 fitted only to the last ECU connected to the RS485 serial bus.KM 73505Fire Alarm ControlModel: K11080BS EN54-2 : 1998BS EN54-4 : 1998Warning SilenceAlarm/FaultSilence/SoundAlarm LampTestGeneral FaultSystem FaultGeneralDisablementPower FaultAlarm/FaultWarning SilencedPower OnDelay OnTest Mode OnFire In ZoneFire In ZoneFireEnable ControlReset Mode Select EnterZone Fault/Test/DisablementZone Fault/Test/Disablement(+10) (+1)System Mode1 2 3 45 6 7 8Sounder Fault/DisablementGeneral System StatusZone Chart123456782 WIRE RS485 SERIALBUS2 WIRE RS485 SERIALBUS2 WIRE RS485 SERIALBUS2 WIRE RS485 SERIALBUSUP TO 4 ECU CONNECTED TO SIGMA CP CONVENTIONAL FIRE PANEL RS485 SERIAL BUSSIGMA CP FIRE PANEL ECU ECU ECU ECUREMOVE LINK LK1 REMOVE LINK LK1 REMOVE LINK LK1 LEAVE LINK LK1 FITTEDC19R21R64L4R77L13R32R67R40C41C4LED11D24R159R43C39C111R98R60F7R12C13C110L3R154R35R68TP3R31R73R167R155L34C40U1 R165TP21R58R11 Q16R46C11C9LK2C12TP17R28C73R70R6C43 C36L8C14L2R34C70LK1D11LED13R62C23R138L6 L5C3R48 R33L32C21C16R57R143R160C24Q35R120TP22L1TP14C17L11C20R142C32C1R26C2R19X3TP18C33R162R71C74 C34R74C69C38C50L43C18C30R110C71C37D10R55R161C49C77C25U2R63U9U11R89 R86C47C5W3W4L16D25C35C28R65C29L44R136R134R157R148R147W2W1R44TP34TP32R61R29R47 R176L9R54 R41L7R90Q3TP23C72R102L14C7R2R3R4R5R10R9D26D28C81C90R72R150R50LED3Q17R27R179R170C31F3C78R158R30R20Q2R69D41TP24TP26TP1BZ1LK4Q30LED8D27R80C8R87R171R91R92C84R163R133R168R180L15U14R153LED10 OPT1LED12C80R51C82U13C46 C42U8 R173R172D41C15C83 R164R88U5D15R94R93D29Q4R25X4R66R56R144Q32R17R18Q10R22R59R169R24LED7 LED6LED5 LED4Q34Q29LED2LED1LK3TP35TP33TP4TP7TP5 TP31TP28TP36D3D1D2D4D9D13D14D43L10C103C106C107U3Y1D12R1R182R166R42R8 R175L33C79C76Q19R96R119R178R95R139R140R23R177C26C6R118R181D16D17C27 U12U4R7Q18C75 R111C91F4C85R105R113Q24Q23R101+ ++kkkkk+k+ISS.01D1058++kkkkkkLK1REMOVE LINK LK1 UNLESS THE ECU IS THE LAST ONE FITTED TO THE SIGMA CP PANEL RS485 BUSREAR VIEW OF ECU CIRCUIT BOARD
