It's a complete flip from the rest of NEC, requiring design around "Keep the fire pumps running at all costs, even if you're in the process of melting down the windings." Separate wiring conduits, handling full locked rotor current indefinitely, etc. The logic, reasonably enough, is that if the fire pumps are running, you probably have way, way bigger problems that will be made worse if your fire pump system trips off to protect the wiring.
