________ shall identify a hydraulically designed sprinkler system with a permanently marked weather proof metal or ridged plastic sign secured with corrosion resistant wire, chain, or other approved means.

________ shall identify a hydraulically designed sprinkler system with a permanently marked weather proof metal or ridged plastic sign secured with corrosion resistant wire, chain, or other approved means.

• A. Original contactor
• B. Senior engineer
• C. Homeowner
• D. AutoCAD drawing

Answer: (A)

Identifying a hydraulically designed sprinkler system with a durable on-site sign is about ensuring the actual installation carries clear, lasting information that stays with the system. The person who should place and verify that sign is the original contractor—the team that installed the system—because they are responsible for the on-site work and must attach a weatherproof marker that meets the spec (metal or ridged plastic, permanently marked, secured with corrosion‑resistant fasteners). This sign communicates to future maintenance crews and inspectors that the system was designed hydraulically and provides the design basis at the location. A senior engineer might specify or approve the design, but they don’t typically install or attach the on-site identification. A homeowner isn’t the proper party responsible for marking the system, and an AutoCAD drawing is just a plan/document, not the physical sign attached to the system.
