This document is a photographic catalog or reference guide displaying plumbing and fire suppression system assemblies across multiple building systems.

The document presents eight system assemblies with corresponding photographs and equipment dataplates. Assembly 33 shows a fire suppression system with white piping, red valves, pressure gauges, and control components installed in an interior space. Assembly 44 includes a boiler makeup water system featuring copper piping, control valves, and an expansion tank, alongside a separate fire suppression assembly with dual black pump units and red manifold components. Assembly 48 depicts a wall-mounted fire suppression system with a large red cylindrical tank and associated piping. Assembly 65 shows a domestic water system with blue and black piping components, blue pressure tank, and associated valves in an interior mechanical room. Each assembly includes a close-up photograph of its equipment dataplate, which displays manufacturer information, specifications, model numbers, pressure ratings, and compliance certifications. The dataplates reference companies such as Amtrol and Wilkins, with specifications indicating maximum flow rates ranging from 20 to 350 gallons per minute and pressure ratings up to 200 PSI. The assemblies appear to be from different building systems or facilities, showing variations in installation complexity and scale.
