4.7-2 Consistency with Emergency Operating Procedures

The alarm system HSI should be consistent with the standards, conventions, and terminology used in the plant emergency operating procedures.

Additional Information:
The alarm system should use the same conventions, such as terminology for plant systems and equipment, identification codes for plant components and parameters, and measurement units, that are used in the main HSI displays and procedures. Defined values, such as alarm setpoints, should be consistent. In addition, if the procedures use coding to present information, such as in graphical displays of a computer-based procedure system, then the alarm system should use the same conventions, such as symbols, icons and coding. For example, if color is used to code priority, it should have the same meaning in the alarm system as in the displays of a computer-based emergency operating procedure.
