An acceptance test is a procedure conducted after work has been completed to verify that a fire protection system performs according to its design and applicable codes. The permit and construction documents are required for the initial installation, modification, or rehabilitation work itself. The acceptance test is a final step in the process of fulfilling the requirements of that permit, not an activity that requires a new, separate permit and submission of construction documents. The AHJ witnesses or receives documentation of the test to approve the system and close out the permit.

B. Rehabilitation: This involves significant restoration or upgrades to an existing system, which requires plan review and a permit to ensure the work meets current codes.

C. Installation: The initial installation of any fire protection system is a fundamental activity that requires the submission of construction documents and the issuance of a permit by the AHJ.

D. Modification: Any alteration or change to an existing fire protection system, beyond minor repairs, requires AHJ approval through a permit to ensure continued compliance.

1. NFPA 1, Fire Code, 2021 Edition.

Section 1.12.6, "Permits." This section explicitly states, "A permit shall be obtained from the AHJ prior to engaging in any of the following activities..." It lists activities such as installing or modifying fire protection systems. Acceptance testing is not listed as an activity requiring a permit; it is a condition of approval for work already permitted.

Section 1.13.1, "General." This section mandates that "construction documents shall be submitted...to the AHJ for review and approval prior to the issuance of a permit..." This applies to installation, modification, and rehabilitation.

2. SFPE Handbook of Fire Protection Engineering, 5th Edition.

Chapter 57, "Fire Protection System Inspection, Testing, and Maintenance," Section 57.3.1, "Acceptance Testing." This section describes acceptance testing as the process to "verify that the fire protection system has been installed in accordance with the design and installation standards." This confirms it is a post-installation verification step, not a pre-construction permitting activity.

3. NFPA 13, Standard for the Installation of Sprinkler Systems, 2022 Edition.

Chapter 29, "System Acceptance." This chapter details the requirements for acceptance testing, including hydrostatic tests and flushing procedures. Section 29.1.1 states, "The installing contractor shall be responsible for...conducting all required acceptance tests." This is presented as a final step before the system is put into service, following the permitted installation.
