Which of the following best describes work Codes in the context of alarm and safety systems?

• A. Codes are optional guidelines
• B. Codes are mandatory requirements that specify when a device or system is required and are minimum requirements
• C. Codes apply only to electrical wiring
• D. Codes are historical documents with no current relevance

Answer: (B)

Codes set the minimum, mandatory standards that determine when a device or system is required and what level of performance is expected. In alarm and safety systems, this means authorities having jurisdiction require specific systems or components based on building type, occupancy, and risk, and they define the baseline expectations for installation, testing, and maintenance. They’re enforceable requirements, not optional guidelines, and they cover more than just wiring—covering overall life‑safety performance. Local amendments may add to the baseline, but the core idea is that codes are mandatory minimum requirements that specify when a device or system is needed.
