According to NFPA 72, the sound pressure level of audible appliances shall be tested upon ___________?

• A. Initial acceptance
• B. Reacceptance
• C. Every other year
• D. Every 5 years

Answer: (A)

Testing the sound pressure level of audible devices is done at initial acceptance to confirm that the installed notification appliances actually meet the required sound levels before the system is put into service. This creates a baseline showing the design goals are achieved in the as-installed condition and ensures occupants will receive the intended warning. After changes that could affect audibility, reacceptance testing is performed, but routine long-interval checks (every year, every few years) aren’t the standard basis for verifying audible SPL under NFPA 72.
