Who can plan, install, or service a fixed ext. system that is not pre-engineered?

The ability to plan, install, or service a fixed extinguishing system that is not pre-engineered is designated to individuals with specific credentials and licenses. A Type A licensee is certified to engage in the design and installation of fixed extinguishing systems, while a professional engineer possesses the necessary education and experience to ensure that these systems are designed effectively and meet safety standards.

Both roles are crucial in dealing with non-pre-engineered systems, which often require tailored solutions and expert oversight to ensure compliance with regulations and safety requirements. Therefore, allowing either a Type A licensee or a professional engineer to manage these tasks ensures that the installation and servicing are conducted by qualified professionals with the appropriate knowledge and certification, collectively guaranteeing public safety and adherence to legal standards.

It's essential to recognize that the other options do not encompass the full scope required for these responsibilities, as they may have limitations in their licensing or expertise related to non-pre-engineered systems.
