The term describing equipment or operation not required by standards or AHJ is which of the following?

• A. Optional
• B. Core
• C. Supplementary
• D. Mandatory

Answer: (C)

In fire alarm design and compliance, there are features that are required and features that are not. When equipment or operation is not mandated by standards or the AHJ, it is described as supplementary. This means it’s added to enhance or extend the system beyond the minimum required performance, but it isn’t necessary for code compliance. It’s the kind of upgrade that improves reliability or capability without being a code or authority having jurisdiction requirement. Optional elements could also be left out without failing to meet standards, but supplementary signals a purposeful enhancement tied to performance or risk considerations rather than simply presenting a possible choice. Core or mandatory, by contrast, refers to elements that must be included, which is why they don’t fit the description.
