Which item is not required on shop drawings by Chapter 7 of NFPA 72?

• A. Riser diagram
• B. Device locations
• C. Wiring schedule
• D. Name of equipment supplier

Answer: (D)

The question tests what shop drawings must include for a fire alarm system under NFPA 72. The important requirements focus on showing how the system is actually installed: where devices will be placed, how circuits run between floors and panels, and the exact wiring details needed for installation and testing. A riser diagram is essential because it maps the vertical distribution of circuits and devices through the building. Device locations are critical to confirm that detectors, notification appliances, pull stations, and other components are placed to achieve proper coverage and accessibility. A wiring schedule provides the conductor types, sizes, and terminations needed to wire the system correctly. The name of the equipment supplier is not required on shop drawings. That information doesn’t affect the installation, testing, or operation of the fire alarm system, and NFPA 72’s shop drawing requirements don’t mandate listing the supplier. Procurement details belong in separate documentation rather than the installation-focused shop drawings.
