5.7 Multiple Cascaded & Synchronized FCPS-24S Power Supplies
In this application, multiple FCPS-24S power supplies, configured as Slave units, are cascaded
from a power supply which is connected to a master FACP NAC programmed for synchronized
output. Each power supply should be set for synchronization which matches the FACP
programming. 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 (Commander II) devices.
Note: FACP supplied selective silence function output will follow panel input.
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.
