4.5 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 panel when the 5499 opens its trouble contacts.

Note:The N.C. contact is the relay contact that is closed when the 5499 has power and there are no trouble con-

ditions.

4.6 Input and Output Wiring

4.6.1 Class A Supervised Wiring

Figure 4-4 shows how to wire for Class A input and output supervision. Use in/out wiring

methods for proper supervision. (Refer to the Appendix for notification appliances compatible

with the 5499.)

Class A Output Notification Appliance Circuits

The configuration shown in Figure 4-4 shows two, 3-amp devices wired as Class A circuits.

When you are using the outputs as Class A circuits, loop the wiring back to the corresponding

circuit pair. For Class A wiring, no external EOL is necessary since it is built into the 5499

board.

Class A Supervised Input Circuits

The configuration shown in Figure 4-4 shows Class A supervised wiring from a fire alarm

control panel to the 5499 board. Pay close attention to the polarities when wiring a panel to the

5499 and follow these requirements:
