The FDU-80G is a compact, cost-effective, 80 character, backlit LCD Fire Annunciator for use with the IFC-320, IFC- 640, and IFC2-640 Fire Alarm Control Panels (FACPs). The FDU-80G mimics the display of the control panel and displays complete system point status information. Up to 32 FDU-80Gs may be connected onto the EIA-485 Terminal Mode port of each control panel. The FDU-80G requires no programming, which saves time during system commissioning. The FDU-80G can be semi-flush mounted to a 2.188�/5.556 cm (minimum) deep, three-gang electrical box or three-gangable electrical switchboxes. Alternately, an SBB-3 surface backbox is available for surface-mount applications.
