CLASS A OPERATION
•
Wire size must be
between 18 AWG (0.8231 mm
and 12 AWG (3.309 mm
•
Maximum wiring distance: 2,500 feet
(762 m).
•
Maximum "T" tapping length:
10,000 feet (3,048 m).
•
Maintain correct polarity on terminal
connections.
•
Do not loop wires under terminals.
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 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
supplied ferrite bead(s) as shown in Figure 4-4.
The illustration below shows both types of wiring.
