For pre-engineered systems, to which authority must the information required by the listed system design manual be made available for verification that the system is within its listed limitations?

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

Answer: (C)

Pre-engineered clean agent systems rely on a system design manual that documents the conditions under which the system is listed and is considered safe to operate. To confirm the installation stays within those listed parameters, the information in the manual must be made available to the Authority Having Jurisdiction—the local fire marshal or building official who has the authority to enforce codes and verify compliance with listing requirements. The AHJ uses the SDM data to check that factors such as room size and configuration, detection and activation criteria, agent concentration, and release characteristics remain within the system’s listed limitations. This ensures the installation is approved and remains within the tested and approved boundaries. The building owner, the insurance carrier, or the system designer do not hold the regulatory authority to verify these listed limitations in the field.
