Installation ANN-BUS Devices
Wiring Configuration
Figure 2.16 illustrates the wiring between the FACP and ANN-BUS devices.
Powering ANN-BUS Devices from Auxiliary Power Supply
Figure 2.17 illustrates the powering of ANN-BUS devices from an auxiliary power supply such as
the FCPS-24FS6/8, when the maximum number of ANN-BUS devices exceeds the ANN-BUS
power requirements.
