2.5.6 Trouble Relay
The 15073 board has a Form C trouble relay built into terminals 7-9 of TB2. The trouble relay will de-
energize under a trouble condition.
A typical application of the trouble relay is to connect the 15073 normally closed (N.C.) contacts in series
with an EOL of a spare IDC or NAC or monitor input from a fire alarm control unit. This will cause a
trouble on the fire alarm control unit when the 15073 opens its trouble contacts.
Note: The N.C. contact is the relay contact that is closed when the 15073 has power and there are no
trouble conditions.
