Which term describes equipment or operation not required by NFPA standards or required by the AHJ?

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

Answer: (C)

When something is not required by NFPA standards or the AHJ, it’s described as supplementary. This term signals that the item adds to the base system to enhance performance or reliability but isn’t mandatory for compliance. The standards establish the minimum requirements, and anything beyond those minimums is considered an add-on, hence supplementary. Even though you may install such features, they aren’t required to meet code or the authority’s mandates. For example, extra remote annunciators or advanced monitoring may be installed to improve operation, but they’re not legally necessary. The other terms describe either things that are essential (mandatory) or simply optional in a more general sense, whereas supplementary specifically denotes non-mandatory add-ons that go beyond the minimum.
