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.
