Note:
The N.C. contact is the contact that is closed when the 5495 has power and there are no trouble conditions.

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 5495.)
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 5495 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
5495 board. Pay close attention to the polarities when wiring a panel to the 5495 and follow these requirements:
• When wiring to Terminal 18 on the 5495, you must use two separate wires. Do not loop a single wire or twist
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.
Must be connected to
a power limited source
