Which items are powered from the DC EMERGENCY Bus?

Explanation:
In an electrical emergency, the DC emergency bus keeps the systems that must work even when the main power is down. It specifically powers safety functions that help contain engine fires and prevent further damage. Engine and APU fire extinguishers rely on this bus to activate and discharge their extinguishing agents, and the fuel and hydraulic shutoff valves use it to isolate fuel and hydraulic lines to reduce fire risk. Other systems that aren’t critical for immediate fire containment aren’t powered by this bus, so they aren’t part of what the DC emergency bus supports. So the DC emergency bus powers engine and APU fire extinguishers as well as the fuel and hydraulic shutoff valves.
