MRP-2002 Series Instruction Manual — P/N 53049:E5 7/28/2016 35ANN-BUS Devices Installation3. Secure the ANN-SEC to the circuit board with the supplied screw.2.7 ANN-BUS DevicesGuidelines• A variety of optional annunciation devices can be connected to an ANN-BUS communicationcircuit. ANN Series devices can be connected to the primary communication circuit (EIA-485)terminals on TB3. A secondary communication circuit (EIA-485) for these devices is availableat TB1 on the ANN-SEC card.• When using one ANN-BUS circuit, up to eight (8) annunciators can be supported.• When using both ANN-BUS communication circuits, the primary circuit supports up to three(3) annunciators and the secondary circuit supports up to (5) annunciators.Compatible devices include:– ANN-80 LCD Annunciator– ANN-80C LCD Indicator (Canadian Applications)– ANN-S/PG Serial/Parallel Printer Interface Module– ANN-I/O LED Driver Module– ANN-LED Annunciator Module– ANN-RLY Relay Module (can be mounted in the FACP chassis)• When operating two ANN-BUS circuits, only one ANN-S/PG Printer module can be used inthe system.• The panel is capable of operating a primary ANN-BUS (TB3) and a secondary ANN-BUS(TB1 on ANN-SEC card) simultaneously.TB1J1ANN-SECFACP Circuit Boardconnector to J13 onmain circuit boardstandoff and screwFigure 2.17 Installing the ANN-SEC Option Card ann-sec2001.wmf!
