What is a key component of acceptance testing before occupancy for a fire alarm and sprinkler system?

• A. The system must be functional and properly integrated with building systems, with no faults, approved as-built documentation, and operator training.
• B. The system must be fully installed, but functional testing is optional.
• C. Only occupancy-based drills are required.
• D. Visual inspection alone is sufficient.

Answer: (B)

Acceptance testing before occupancy focuses on proving that the fire alarm and sprinkler system is ready to operate as designed and will protect occupants. It requires the system to be fully installed and properly integrated with building systems, with all faults cleared, and with approved as-built documentation and completed operator training. A crucial part is functional testing, which verifies that detectors respond, alarms and notification devices operate, interlocks and sequences trigger correctly, water supplies and valves function, and that the overall system behaves as intended in real scenarios. Visual checks alone or drills without confirming actual system performance do not ensure reliability or compliance, so functional testing is essential.
