Installation ANN-BUS Devices
3. Secure the ANN-SEC to the circuit board with the supplied screw.
2.9 ANN-BUS Devices
Guidelines
• A variety of optional annuciation devices can be connected to an ANN-BUS communication
circuit. 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 available
at 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-RLED Annunciator Module (red alarm LEDs only)
– ANN-RLY Relay Module
• When operating two ANN-BUS circuits, only one ANN-S/PG Printer module can be used in
the system.
• The panel is capable of operating a primary ANN-BUS (TB3) and a secondary ANN-BUS
(TB1 on ANN-SEC card) simultaneously.
