The hydraulic design information sign for a sprinkler system shall include each of the following except:

• A. the size of the pump
• B. the system type
• C. the location of the water supply
• D. the design head

Answer: (A)

Hydraulic design information signs are meant to convey the essential data that define how the sprinkler system will perform hydraulically. The sign should identify the system type (for example, wet, dry, or deluge) so responders know what kind of water-filled piping they’re dealing with. It also needs the location of the water supply, so you know where the water is coming from and how it’s connected to the system. The design head is included to indicate the pressure the system is designed to deliver at the points of interest, reflecting the hydraulic requirements the system must meet under design conditions. The size of the pump isn’t part of this sign because pump size is a separate equipment detail. It can be chosen to meet the required design head and flow, but it doesn’t define the hydraulic design data itself. The sign focuses on the hydraulic criteria needed to verify and understand system performance, not on the pump’s physical rating.
