Which of the following is NOT a responsibility of a fire alarm tech?

The role of a fire alarm technician primarily focuses on the installation, maintenance, and testing of fire alarm systems. While they have a significant responsibility in ensuring that these systems function correctly and meet safety standards, the design of fire alarm layouts typically falls outside their scope of work. Fire alarm designers or engineers are usually the professionals responsible for planning and designing the layout of the fire alarm systems, ensuring compliance with codes, regulations, and safety needs.

The responsibilities of a fire alarm technician do include supervising other technicians, maintaining fire alarm systems, and testing alarm systems to ensure they operate properly. These tasks directly align with ensuring functionality and compliance with safety standards. However, the technical and legislative complexity of creating system layouts is generally reserved for trained professionals who specialize in that area. Thus, the correct answer accurately reflects the boundaries of a fire alarm technician's normal responsibilities.
