a. Connect one lead to the common (COM) terminal.
b. Connect the other lead to the normally closed (NC) or normally open (NO) terminal.

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.
