How do you verify a SHS installation meets NFPA 2001 requirements during testing?

• A. Visual inspection only.
• B. Only 24-hour test.
• C. Acceptance tests including pre-discharge alarm verification, system integrity checks, agent release timing, airflow considerations, and post-discharge verification.
• D. No testing required.

Answer: (C)

The key idea is that verifying an SHS installation to NFPA 2001 requires a comprehensive acceptance test that proves the system will perform as designed from start to finish, not just look correct. The best answer reflects this by including all the essential checks: pre-discharge alarm verification to confirm that alarms and warnings function so occupants are alerted before any discharge; system integrity checks to verify that valves, actuators, piping, detection, and supervision components are ready and mutually compatible; agent release timing to ensure the sequence and delay times occur exactly as designed; airflow considerations to confirm the agent will be distributed effectively throughout the protected space and that there are no dead zones; and post-discharge verification to confirm safety after discharge, including agent concentration decay and safe re-entry conditions. Together, these elements demonstrate that the system will operate correctly under NFPA 2001 requirements.

Visual inspection alone cannot confirm performance, a single 24-hour test does not address all necessary verification steps, and no testing at all is not acceptable.
