The installation of systems for smoke alarms and audio systems falls primarily under the scope of residential wiremen. These professionals specialize in wiring and installing electrical systems within residential buildings, which includes installing devices that ensure safety (like smoke alarms) as well as systems that enhance livability (such as audio systems).

Residential wiremen are trained to handle the specific needs of homes, including compliance with local building codes and safety standards associated with these installations. They possess the necessary skills to navigate the challenges that come with working in residential environments, such as accessing tight spaces, ensuring proper connections, and integrating various home systems.

In contrast, substation technicians generally focus on high-voltage electricity distribution and the maintenance of substations, electric vehicle technicians specialize in electric vehicle systems and charging infrastructure, and power plant operators manage the generation and distribution of electricity at a plant level. Their training and responsibilities do not encompass the specifics of installing residential alarm systems or audio systems, making residential wiremen the appropriate choice for this task.
