4.4.1 Common Trouble Relay
The 5499 has a Form C trouble relay built into Terminals 11-13. The relay provides a
normally open and a normally closed contact, both of which are rated at 2.5A. The
trouble relay will deactivate under any trouble condition.
A typical application of the trouble relay is to connect the 5499 normally closed (N.C.)
contacts in series with the EOL supplied with the fire alarm control panel. This will
cause a trouble on the fire alarm control panel when the 5499 opens its trouble
contacts.
Note: The N.C. contact is the contact that is closed when the 5499 has power and there are no trouble
conditions.
