4.5 Notification Appliance Wiring
Note: Not all devices can use the sync feature. Be sure to check Appendix A to ensure the device you
have chosen will work with this feature.
4.5.1 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 Appendix A for notification
appliances compatible with the 5499.)
Class A Output Notification Circuits
The configuration shown in Figure 4-4 shows two, 3 A devices wired as Class A.
When 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:
• When wiring to Terminal 18 on the 5499, you must use two separate wires. Do not
loop a single wire or twist two conductors together.
• Do not use notification appliances on Class A circuits connected to a 5499 for
input. The 5499 will detect voltage across the input circuits, but is not designed to
Important!
For all synchronization options, input 1 is the strobe input and input 2 is the audible input. The signals to input 1
and input 2 must be DC signals for the synchronization patterns to work properly. When it is desired to activate
both strobes and audibles, input 1 and input 2 must be active. If it is desired to only activate strobes, then input 1
must be active and input 2 must be inactive. The audible can be deactivated and reactivated at any time by
changing the signal at input 2 as long as input 1 remains active. If input 1 is not active, then input 2 is ignored.
