Diagram a wet-pipe riser assembly from memory, labeling the check valve, alarm valve, main drain, test valve, flow switch, gauges, and inspector's test connection in correct order.

Explain how a dry-pipe system's hydraulic calculation must account for air pressure and the dry-pipe valve friction loss, and compute a simple dry-pipe example.

List the NFPA 13 requirements for sprinkler obstructions (18-inch rule, 3x rule for structural members, and obstruction distances) and apply them to three sketch scenarios.

Specify the correct sprinkler temperature rating and response type (quick, standard, special) for given occupancy and ceiling conditions, citing the applicable NFPA 13 table.

Determine hanger spacing, rod size, and seismic bracing requirements for Schedule 40 steel pipe in a given bay width and building height, per NFPA 13 Chapter 17.

Trace the acceptance test sequence for a new wet-pipe system: hydrostatic test pressure and duration, flushing, flow test, and main drain test, with pass/fail criteria.

Identify the required clearances for sprinklers relative to ceilings, walls, and storage, and calculate minimum clearance for a rack storage scenario.

Compute net positive suction head available (NPSHa) for a fire pump drawing from a ground-level tank and from a city main, and compare to the pump's NPSHr.

Read a fire pump performance curve and determine churn pressure, rated flow, 150% overload flow, and the maximum allowable shutoff pressure per NFPA 20.

Explain the acceptance test requirements for a fire pump, including the 150% flow test duration, and identify the four test points recorded.

Size a standpipe system for a five-story building, selecting Class I, II, or III, and determine the minimum residual pressure at the topmost outlet.

Describe the requirements for a fire department connection, including location, height, pipe size, and the check valve arrangement.

Build a monthly, quarterly, annual, and 5-year ITM task matrix from NFPA 25 for wet-pipe, dry-pipe, and standpipe systems, listing the specific task at each frequency.

Explain the main drain test procedure, the expected static and residual pressure readings, and how to interpret a pressure drop indicating a supply problem.

Describe the dry-pipe valve trip test procedure, including the required frequency, and identify the conditions that require an internal inspection.

Interpret a failed flow test result and list the diagnostic steps in order, from the inspector's test connection back to the water supply.

Distinguish between an impairment and a deficiency under NFPA 25, and state the required notification and corrective action timeline for each.

List the Nevada State Fire Marshal licensing requirements for a fire sprinkler contractor, including the license classification, qualifying party requirements, and renewal cycle.

Explain the Nevada contractor licensing rules on bid limits, the requirement for a qualifier to be actively engaged, and the consequences of unlicensed contracting.

Identify the key Nevada-specific amendments to the adopted fire code, including any local sprinkler thresholds for one- and two-family dwellings and small commercial occupancies.

Describe the permit and plan review process for a fire sprinkler installation in a Nevada jurisdiction, including who may submit and what inspections are required.

Summarize Nevada lien law basics and contract requirements applicable to fire protection subcontractors, including notice requirements.

Produce a job hazard analysis for a sprinkler installation task involving overhead work, pipe cutting, and ladder or lift use, identifying controls for each hazard.

Explain the plan review submittal requirements under NFPA 13, including what working plans must show and the qualifications of the person preparing them.

Describe the sequence of inspections required during construction and the conditions that must be met before each is signed off.

Identify the record-keeping and as-built documentation required at project closeout, including the material and test certificate.

Compare the design criteria for residential sprinklers, ESFR, and CMSA sprinklers, stating where each is permitted and the key density and pressure differences.

Explain the requirements for clean agent, water mist, and foam-water systems and identify the occupancies where each is an acceptable alternative to a standard sprinkler system.

Complete a timed 100-question mixed practice exam covering all eight domains and score your performance by domain to identify remaining weak areas.

Re-derive the density/area selection and one full hydraulic calculation from memory as a final retention check.

Review all previously missed practice questions and write a corrected explanation for each.
