Step 2:
Insert the twisted-pair wire into the terminal block labeled
FTT (Figure 11) in the first Reader and run it out the
conduit chase.
Step 3:
Run the twisted pair through the conduit chase of the
second Reader and insert the twisted pair wire into the
FTT terminal block. Each terminal in the FTT terminal
block can hold up to four wires, depending on gauge.
Note: When connecting Readers to each other, remember that
shorter cabling makes for a better network because it improves
transmission.
Connecting an FTT Reader to a Device
The FTT Reader has two outputs to control devices. These outputs
can be found on the FTT Terminal block (Figure 11).
The terminals in the FTT terminal block are for the following:
