5.5 Master FACP With Slave HPF24S Power Supply
In this application, an HPF24S power supply, configured as a Slave unit, is connected to a master
FACP NAC programmed for synchronized output. The power supply should be set for
synchronization which matches the FACP programming.
Notes: The following notes apply to Figures 5.5.
1. Refer to NFPA 72, Chapter 4-4, Visible Characteristics, Public Mode.
2. Use only devices from the same manufacturer in each system.
3. Some FACPs do not provide sync capability from the NAC output. Refer to the FACP user
manual to determine the source of the sync signal.
4. If the FACP has a dedicated sync output connector, wire the sync output connnector to the
HPF24S Sync In terminals, terminals 1 and 2 on TB4. Refer to the Supervised Master/Slave
Connections (Remote Sync Source) in 5.5b.
