5.8 Cascaded FCPS-24S Supplies from Nonsynchronized Source
In this application, multiple slave FCPS-24S power supplies are cascaded from a master power
supply which is connected to an FACP NAC with nonsynchronized output. Each power supply
should be set for synchronization which matches the master power supply. A maximum of ten
cascaded supplies can maintain synchronization using System Sensor and Wheelock devices while
a maximum of four can maintain synchronization using Gentex devices.
Note: The following notes apply to this illustration
1. Refer to NFPA 72, Chapter 4-4, Visible Characteristics, Public Mode.
2. Use only devices from the same manufacturer in each system.
