Description
The N-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 N-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.
