Exam tip

When inspecting existing buildings, it's crucial to consider the current code requirements and not just the code in effect at the time of installation.

Why C is correct

Section 907.2.2 of the 2021 International Building Code requires that fire alarm systems be maintained and upgraded to meet current code standards. The inspector should recommend that the owner consult with a fire protection engineer to determine the necessary upgrades, rather than immediately replacing the system or accepting it as compliant with older standards.
