Which DCS screen is used for testing the annunciator?

The service adjustments screen is utilized for testing the annunciator because it typically provides access to functionality necessary for modifying or testing system components, including alarms and annunciators. This screen allows operators or maintenance personnel to check the performance and functionality of the annunciators by simulating alarms or conditions that should trigger them.

The configuration screen focuses on setting up system parameters and might not provide the real-time testing capability needed for annunciators. The status monitoring screen is designed for viewing current system states and alerts but does not offer the ability to perform tests. The diagnostic tools screen, on the other hand, is generally used for troubleshooting by providing detailed data and analysis but may not be specifically tailored for the direct testing of annunciators. Thus, the service adjustments screen is the appropriate choice for such testing tasks.
