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.
