2.8.3 ANN-80(C) Remote Fire Annunciator/Indicator
The ANN-80(C) Annunciator/Indicator is a compact, 80 character, backlit LCD remote fire annun-
ciator which mimics the FACP display. It also provides system status indicators for AC Power,
Alarm, Trouble, Supervisory and Alarm Silenced conditions. The ANN-80 Annunciator provides
buttons for remote Reset, Silence, Acknowledge, and Drill of the FACP. The ANN-80C Indicator
does not provide these buttons. Communication between the ANN-80(C) and FACP is accom-
plished 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, fil-
tered, power supply.
