Which individual is NOT likely to perform maintenance in accordance with service instructions?

Administrative personnel are typically not involved in the hands-on maintenance of fire alarm systems. Their roles usually focus on management, documentation, scheduling, and other support functions rather than the technical aspects of service, installation, or inspection of fire alarm systems.

Service personnel are directly responsible for maintaining and repairing systems, ensuring they function properly. Installation personnel are tasked with setting up these systems and might also be involved in initial testing and quality assurance. Inspection personnel evaluate systems for compliance with safety standards and regulations, often performing functions that require technical expertise in the operation of the systems.

In contrast, administrative personnel lack the technical training or responsibilities that align with performing maintenance tasks according to service instructions, thereby making them the least likely group to engage in such activities.
