Fire protection licensing in Wisconsin
Wisconsin's Department of Safety and Professional Services (DSPS) licenses automatic fire sprinkler work under SPS 305. Contractors, journeyman fitters, maintenance registrants and system testers must hold DSPS credentials, mostly by state exam. NICET Water-Based Layout Level III is one route to the contractor exam, and NICET Inspection and Testing of Water-Based Systems Level II is one route to the system tester credential. DSPS also certifies fire detection, prevention and suppression inspectors based on NFPA Fire Inspector I or an equivalent it approves.
