ANN-S/PG interface modules connect 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.
ANN-S/PG interface modules and FACPs communicate over a 2-wire serial interface employing the ANN-BUS communication format. An additional two wires are used for 24V DC power. A single 4-conductor unshielded cable may be used for both power and data communications. Up to eight ANN-S/PG interface modules may be connected to the ANN-Bus of each FACP.
