Commissioning in fire protection systems is defined as a process that:

• A. A process verifying that fire protection systems perform correctly through testing, adjustment, and balancing before occupancy
• B. An informal walk-through after occupancy
• C. A budget review of fire protection measures
• D. A post-occupancy maintenance plan only

Answer: (A)

Commissioning is about proving that fire protection systems perform as designed through a planned sequence of tests, adjustments, and balancing before the building is occupied. This process verifies that all components work together correctly, that hydraulic and functional performance meet design criteria, and that proper documentation and acceptance are in place for the owner and authorities having jurisdiction. It goes beyond a simple check; it involves rigorous testing of controls, alarms, interlocks, and system interfaces and may include pump performance, valve operation, sequence of operations, and documentation of results. The other options describe activities that do not systematically verify performance before occupancy: a casual walk-through after occupancy lacks the formal testing and documentation; a budget review is financial, not a test of system performance; a post-occupancy maintenance plan focuses on ongoing upkeep rather than initial verification of function.
