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.
RUI cabling can be accomplished either through Class A (loop) or Class B (spur) wiring.
Class A wiring allows transponder cabinets to communicate with the host panel even in
the event of a single open or short circuit somewhere in the loop.
Class B wiring allows “T” tapping, and therefore requires less wiring run per installation
than Class A.
If the transponder(s) have more than 40 detectors connected to them in total, Class A
(loop) wiring must be used to meet the requirements of AS 1670.1.
RUI wiring does not require end-of-line resistors, because each TIC communicates
directly to the CPU.
Note: Use the supplied ferrite beads with TICs. Loop wires once through
the ferrite bead(s) as shown in Figure 3-5.
The illustration below shows both types of wiring.
