The TIC must be connected to the host panel via RUI cabling. This section explains how
to wire the two together, and how to set up a system with multiple transponders connected
to the same host panel.
to wire the two together, and how to set up a system with multiple transponders connected
to the same host panel.
RUI cabling can be accomplished either through Class A or Class B wiring.
Class A wiring allows transponder cabinets to communicate with the FACP even in the
event of an open circuit somewhere in the loop. Class A wiring requires that two wires are
routed from the CPU motherboard to each TIC, and then back again to the CPU
motherboard.
Class B wiring allows “T” tapping, and therefore requires less wiring distance per
installation than Class A. Additionally, Class B wiring does not require end-of-line
resistors, because each TIC communicates directly to the CPU.
Note: Use supplied ferrite beads with TICs. Loop wires once through the

Note: Use supplied ferrite beads with TICs. Loop wires once through the
supplied ferrite bead(s) as shown in Figure 4-4.
The illustration below shows both types of wiring.
