Serial/Parallel Printer Interface Module
Also Known As ANN-S/PG
The ANN-S/PG Interface module connects either a serial or parallel printer with a compatible Fire Alarm Control Panel (FACP) to print real-time logs of system events, detector status reports, and event histories. The ANN-S/PG and the FACP communicate over a two-wire serial interface employing the ANN-BUS communication format. An additional two wires are used for 24-volt DC power. A single four-conductor unshielded cable may be used for both power and data communications. Up to eight ANN-S/PGs may be connected to the ANN-Bus of each FACP.
