The information a sign provides is important.
In addition to being required by NFPA standards, a hydraulic data sign can be beneficial because it records information that’s important for fire sprinkler system inspectors and engineers.
NFPA 13 requires that all automatic sprinkler systems undergo monthly assessments to ensure that all system components are working as they should. As part of this process, a hydraulic data sign is present to provide details about the system’s specific capabilities and service history. Think of a hydraulic data sign as a list of design criteria that can explain what the system can do and how service professionals should interact with it.
When such data is present, conveniently displayed, and readily available on a hydraulic data sign, the job of a technician, inspector, or engineer is made that much easier.
