Which of the following is NOT a required entry in the FLS Logbook after testing a smoke control system?

The correct answer is that the manufacturer's company address is not a required entry in the FLS Logbook after testing a smoke control system. The FLS Logbook is primarily focused on documenting specific operational details that are directly relevant to the safety and functionality of the smoke control systems.

Key entries that are required include the date of the test, which provides a record of when the testing occurred; the names of the crew involved, which ensures accountability and traceability of personnel who conducted the test; and the outcome of the test, which is critical for evaluating the performance of the smoke control system and determining whether it meets safety standards.

The manufacturer's company address, while it may be useful information for reference, does not directly impact the operational status or results of the smoke control system in the context of immediate fire safety procedures. As such, it is not considered essential for inclusion in the logbook entries required following a test.
