I’m Marshal David, a fire alarm design specialist focused on NFPA 72 documentation for U.S. building projects. I prepare fire alarm permit drawings, shop drawings, riser diagrams, battery and voltage drop calculations, device layouts, and AHJ correction revisions. I work from architectural plans, existing system drawings, equipment data and project requirements to produce clear, organized documentation for contractor, installer and review needs. Send your project plans and scope to get started.
