Which of the following groups is typically responsible for performing fire system inspections?

External certified professionals are typically responsible for performing fire system inspections due to their specialized training and expertise in fire safety and alarm systems. These professionals possess the necessary certifications and knowledge required to assess the functionality and compliance of fire safety systems with relevant codes and standards. Their involvement ensures that inspections are thorough, accurate, and compliant with regulations, which is crucial for maintaining the safety of the building's occupants.

Building maintenance staff may be familiar with basic fire safety protocols, but they usually lack the specialized knowledge required to conduct detailed inspections. Tenant volunteers may not have the necessary training or liability coverage to perform such inspections, which can lead to oversight or non-compliance with safety regulations. Local law enforcement typically does not engage in fire system inspections; their role is more focused on public safety and response rather than preventive inspections. This makes external certified professionals the most qualified choice for conducting thorough fire system inspections.
