A firefighter is reviewing a pre-plan diagram for a warehouse. The main entrance is on the South wall ('Alpha' side). Inside, a hallway extends directly North. The Fire Alarm Control Panel (FACP) is on the East wall, 10 feet North of the entrance. The sprinkler riser room is shown as the first door on the West wall of this main hallway. The gas meter shut-off is located on the exterior of the building at the Northwest corner. To shut down the building's sprinkler system, which direction should the firefighter turn from the main hallway?
