When performing repairs on preaction and deluge systems, what should you consult regarding supervisory air pressure?

Consulting the manufacturer's specifications is essential when performing repairs on preaction and deluge systems, particularly regarding supervisory air pressure. Manufacturers provide specific guidelines and requirements that are tailored to their equipment, including the optimal pressure settings needed for proper functionality and safety. These specifications ensure that the systems operate effectively, and any deviations may put the system at risk for malfunction or failure.

While local building codes, NFPA standards, and industry best practices are important for overall compliance and safety, they often provide a broader framework rather than detailed operational specifics for a particular system. Manufacturer specifications are critical for addressing the unique characteristics and requirements of the equipment being repaired. Adhering to those specifications can prevent issues that arise from incorrect pressure settings, ultimately ensuring reliable system performance.
