2.8.3 N-ANN-80(C) Remote Fire Annunciator/Indicator
The N-ANN-80(C) Annunciator/Indicator 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 N-ANN-80 Annunciator
provides buttons for remote Reset, Silence, Acknowledge, and Drill of the FACP. The N-ANN-
80C Indicator does not provide these buttons. Communication between the N-ANN-80(C) 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.
