The FIT is provided with a RJ-12 connector cable that is connected to the FC/SA 6 pin RJ-12 jack found on most Johnson Controls® controllers. The FIT also has a Four-Pin removable terminal block that is used to wire the FIT to the FC/SA bus. When the FIT is connected to the FC bus, it can only see the devices directly connected on the FC bus, but not the SA bus.
