Which sign specifically indicates the hydraulic design details of a sprinkler system?

The hydraulic design information sign is specifically designed to convey the essential hydraulic details of a sprinkler system. This sign typically includes crucial information, such as the required flow rates, pressures, and the specific configuration of the system that must be maintained to ensure effective performance during a fire event.

This sign is particularly important because it provides guidance to fire protection personnel and systems designers about the operational parameters under which the sprinkler system was designed to function. These details are vital for ensuring that the system will perform adequately in an emergency situation, as any deviations from the designed hydraulic parameters could result in ineffective system performance.

In contrast, the system control sign generally identifies the control valves and system monitoring devices, the installation instruction sign provides guidelines for the installation process rather than operational details, and the emergency shutoff sign indicates the location of shutoff valves during emergencies without providing specifics about the hydraulic system.
