Which component is not part of a termination connection for standpipe systems?

In a standpipe system, the termination connection typically consists of components that facilitate the connection and use of fire hoses, as well as components that help manage and monitor the water flow within the system. Hose connections, control valves, and drain valves are all integral parts of this connection.

Hose connections allow firefighters to attach hoses to the standpipe, enabling them to draw water for firefighting operations. Control valves regulate the flow of water within the standpipe system, providing firefighters with the ability to manage the amount of water supplied. Drain valves are essential for draining the system to prevent water from stagnating and to allow for maintenance or inspection.

Pressure gauges, while important in the overall function and monitoring of the standpipe system, are not part of the termination connection. They are typically located elsewhere in the system to ensure that pressure levels are within safe operational limits. Thus, the correct answer identifies the component that does not belong to the termination connection specifically.
