Section 1: FDU-80 Annunciator
The FDU-80 Annunciator is a compact, 80-character, backlit LCD fire
annunciator designed for use with the AFP-300/400 and AFC-600
FACPs (Fire Alarm Control Panels).
It should be noted that the FDU-80
Annunciator display will mimic the FACP display.
The FDU-80 is capable of displaying English-language text of system
point status including device type, independent
point
alarm, trouble or
supervisory, zone and custom alpha labels programmed into the control
panel. The FDU-80 also provides system status LEDs to display Power,
Alarm, Trouble, Supervisory and Alarm Silenced conditions. The
FDU-80 is capable of performing system acknowledge, silence, drill
and reset remotely.
Communication between the FACP and the FDU-80 is accomplished
over a two-wire serial interface employing the EIA-485 communication
standard. Up to 32 annunciators may be connected to the two-wire
EIA-485 circuit. The annunciators may be powered from the host FACP
or remote UL listed, filtered, power supplies.
