5.6 Multiple Synchronized FCPS-24FS Power Supplies
In this application, multiple FCPS-24FS power supplies, configured as Slave units, are connected
to a master FACP NAC programmed for synchronized output. Each power supply should be set for
synchronization which matches the FACP programming.
Note: FACP supplied selective silence function output will follow panel input.
Note: The following notes apply to Figure 5.6
1. Refer to NFPA 72, Chapter 4-4, Visible Characteristics, Public Mode.
2. The NAC output devices from one power supply must be partitioned with walls and/or floors
from the next power supplies and their NAC output devices.
3. Use only devices from the same manufacturer in each system.
4. Relay Modules programmed as silenceable points will selectively silence the notification
appliances when its Normally Open contact (7 & 9) closes
