The alarm system HSI should be consistent with the standards and conventions used for the HSIs for other displays and controls in the control room.
Additional Information:
The alarm system should use the same conventions such as symbols, icons, acronyms, coding, and measurement units that are used in the main HSI displays and procedures. While some minor differences may exist, the alarm system should never use a display feature, such as coding, in a way that is different from or conflicts with other HSIs. For example, if color is used to code priority, it should have the same meaning in the alarm system as in the process displays.
