What do FAT and SAT stand for in BAS commissioning, and what do they verify?

• A. Firmware Activation Test and Structural Analysis Test.
• B. Functional Analysis Test and System Automatic Test.
• C. Factory Acceptance Test and Site Acceptance Test; verify equipment and system performance against requirements and in-site operation.
• D. Final Audit Trial and System Acceptance Time.

Answer: (C)

In BAS commissioning, FAT and SAT refer to Factory Acceptance Test and Site Acceptance Test. They verify that equipment and the whole system meet the project requirements, first in the controlled factory environment and then in the actual site under real operating conditions. The Factory Acceptance Test checks hardware, firmware, sensors, communications, and initial control sequences to ensure everything functions to design before shipment. The Site Acceptance Test validates installation quality, network integration, point-to-point control logic, alarms, trends, and performance under real loads and occupancy, confirming the system operates correctly in its intended environment. Together, they confirm that both the equipment and the installed system perform as specified and are ready for full operation.
