Can wiring from FACP to an external battery (24V 40Ah) in its own conduit be run through the same 4x4 junction box as wiring from FACP to power supplies and power supplies to notification appliances?

Is the cable from the FACP to the power supplies the FACP on-board NAC circuit going out to trip the remote booster power supplies? If "yes", then the answer is probably, "no". The cable going from the battery box to the FACP is considered non-power limited, while the NAC's are power limited and they should not be mixed in the field.
