5.6 Multiple Synchronized FCPS-24S Power Supplies
In this application, multiple FCPS-24S 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 outputs 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
