2.8.3 GFANN-80 Remote Fire Annunciator
The GFANN-80 Annunciator is a compact, 80 character, backlit LCD remote fire annunciator which mimics the FACP display. It also
provides system status indicators for AC Power, Alarm, Trouble, Supervisory and Alarm Silenced conditions. The GFANN-80 Annunci-
ator provides buttons for remote Reset, Silence, Acknowledge, and Drill of the FACP. Communication between the GFANN-80 and
FACP is accomplished over a two wire serial interface employing the ANN-BUS communication format. The devices are powered, via
two additional wires, from either the host FACP or remote UL-listed, filtered, power supply.
