Which entity must have access to the information required by the listed system design manual for verification that the system is within its listed limitations?

• A. Building Owner
• B. System Manufacturer
• C. Authority Having Jurisdiction
• D. Insurance Carrier

Answer: (C)

Access to the information in the system design manual for verification that the system stays within its listed limitations is required by the Authority Having Jurisdiction. The AHJ is the regulatory body responsible for confirming that the installation complies with the listing, the manufacturer’s design specifications, and applicable codes. The system design manual lays out the specific limitations and acceptance criteria, and the AHJ uses that information during plan review, commissioning, and inspections to ensure the installation is safe and within its listed parameters. The building owner may retain records and oversee maintenance, the manufacturer provides the design documentation, and the insurance carrier may review risk, but none of them have the formal verification authority that the AHJ has.
