FT128 External Termination
The FT128 Main Board 4556 is normally mounted on the rear of the front door. In order to
avoid the field wiring termination on a swing door, an adapter board SUB836
connected to the main board. The new version of the adapter board is plugged in the screw
terminals of the 4556 board and interfaced to another external termination board SUB835
mounted on the equipment plate. The adapter board SUB836 is connected to the
termination board SUB835 via ribbon cable.
The FT128 has only one programmable relay. To increase the number of programmable
relays in the standard FT128 system, another relay with two changeover contacts is added
to the termination board to provide 2 sets of additional changeover relay contacts. The

The adapter board shown in Figure 9 and external termination board shown in Figure 10 use a new PCB revision (PCB250
Rev 5). In all previous revisions, the adapter board is soldered in the terminals of FT128 main board (4556).
