Step 5 Connect one set of alarm indicator wires to the alarm terminal block as follows:
a. Connect one lead to the common (COM) terminal (Figure 5-37).
b. Connect the other lead to the normally closed (NC) or normally open (NO) terminal.
Caution Figure 5-37 shows the wiring configuration for normally open (NO) alarm relays. If you are wiring the
router in series with other equipment for the alarm indicators, use the normally closed (NC) terminals.
If you are wiring the router in parallel with other equipment for the alarm indicators, use the NO
terminals.
