A21 - Encl-33_702-D678-01-0 Fire detection sys.pdf

This file appears to be a technical drawing or schematic showing three different views (top, middle, and bridge deck) of what appears to be a ship's fire detection system layout. The drawing provides detailed views of sensor/detector placement, system components, and infrastructure routing throughout the vessel. The document appears to be labeled as "Fire detection sys" with drawing number 702-D678-01-0 and is related to the Murden Shipyard Repair Services solicitation (W912PM25Q0009). The drawing shows comprehensive fire detection coverage across multiple decks with clearly marked system components and appears to be an engineering specification document intended to guide installation or maintenance of the ship's fire detection infrastructure.
