This guide is an intensive, no-nonsense preparation for the Minnesota Journeyman Sprinkler Fitter exam, highlighting the critical need to master both NFPA standards and Minnesota's specific, often stricter code requirements. It emphasizes that while national guidelines provide a foundation, Minnesota's code always takes precedence, particularly concerning licensing, system design, and component specifics like FDC placement or valve monitoring exceptions. The training delves into various sprinkler system types, their installation nuances, and crucial inspection, testing, and maintenance (ITM) protocols, constantly reminding listeners to pay laser-sharp attention to numerical values, keywords, and potential "gotcha" questions that differentiate a general understanding from the precise knowledge needed for certification and safe practice in the field.
