example, Alarm Input 1 produces the CLI message “Alarm Input 1 Detected”.

• Momentarily short-circuit pins for each alarm input pair (l, 2, 3 in Figure 6-31) to simulate an
alarm contact closure. See Alarm Input Connections on
page 6-31 .
Requirement: Contact closure on any alarm input wire pair produces Minor Alarm indica-
tion on active Controller card (see Figure 6-32).
