B162_Fire_Protection_DWG.pdf

This document is a detailed architectural floor plan and fire protection system schematic for Building 162 at Otis Air National Guard Base, prepared for the Massachusetts Military Division's 102d Intelligence Wing. The technical drawing includes a comprehensive floor layout with gridded sections, detailed annotations, and two technical detail diagrams showing a "Preaction System Control Valve" and a "Double Check Valve Assembly" on the right side of the document. The drawing is marked with the drawing number OTS-210-221 and includes a legend explaining various symbols and markings used throughout the plan.

The floor plan provides a precise architectural representation of the building's interior configuration, with numerous rooms and spaces meticulously mapped out across multiple levels. The technical details on the right side of the document suggest a sophisticated fire protection system design, with specific components and valve assemblies outlined to ensure comprehensive fire suppression capabilities. The drawing appears to be part of the technical documentation supporting the ITB SPBN253101 for fire protection system inspection and certification, which requires a licensed professional to conduct thorough inspections of the facility's internal fire suppression systems and provide detailed reporting on system reliability and potential deficiencies.
