NFPA 72 code sections · Fire Alarm Design Principles
Design documents first, approval second, installation third
Chapter 7 lays out the paper trail. Design (layout) documents — the drawings and specifications that describe what the system has to do — are prepared by someone experienced in fire alarm design and submitted to the AHJ before installation begins, where the jurisdiction requires a permit. The code says plans are prepared by persons experienced in the proper design, application, installation and testing of fire alarm systems, and evidence of qualification (a PE stamp or NICET level, depending on the state) is provided when the AHJ asks. Starting rough-in before approval means tearing out whatever the plan reviewer rejects.

On the job
An electrical contractor pulls fire alarm cable from a lighting plan, then submits drawings for 'record'. Plan review rejects the layout — strobe candela and detector spacing are missing, and the firm has no qualified designer. Half the boxes move. The project now budgets for a NICET-certified designer and a submittal before anyone pulls wire.
