Which of the following is NOT one of the systems a generator is dedicated to?

A generator is typically dedicated to supporting specific critical systems, ensuring that these systems remain operational during power outages or disruptions. In this context, the systems mentioned refer to various operational components that require guaranteed power supply to function effectively.

Building 101, as referenced in the question, does not refer to a specific operational system but rather to a physical location. Generators are usually linked to systems directly involved in operations, such as either communication or information processing systems, rather than associated with a building entity itself.

The other options represent specialized systems that likely require a dedicated power source to maintain functionality. PAR (Potential Assessment Receiver) and DASR (Data Acquisition and Storage Recorder) are systems that would rely on uninterrupted power for safety, data integrity, and operational continuity. A transmitter is also critical for communication, emphasizing the necessity of reliable power supply.

Thus, identifying Building 101 as not being a dedicated system for which a generator would be responsible aligns with the understanding that generators are meant to serve systems directly impacting operations.
