MD Fire Sprinkler study plan

Identify the occupancy hazard classifications and explain how each drives sprinkler design density selection

Compute required design density, remote area size, and minimum operating pressure for a light hazard wet system from a given scenario

Diagram the four major sprinkler system types (wet, dry, preaction, deluge) and label when each is required or preferred

Define hydraulic terms-density, discharge, remote area, safety margin-in writing without referring to notes

Calculate sprinkler spacing, coverage area per head, and branch line limits for a given ceiling configuration

Size pipe runs using the Hazen-Williams method and explain how C-factors change for steel, copper, and CPVC

Evaluate the effect of a 10% design safety margin and elevation/backflow losses on total system demand

Compare tree, loop, and grid piping layouts for pressure loss and reliability

Sequence the installation of underground mains, risers, branch lines, and heads in correct order of operations

Explain spacing and obstruction rules for heads near joists, ducts, and walls

Select the correct hanger type, spacing, and bracing method for steel and CPVC pipe

Identify required components-check valves, flow switches, inspector's test valves, drain valves-and where each is installed

Perform and document the hydrostatic test procedure including test pressure, duration, and pass criteria

Describe acceptance testing for dry and preaction systems including air pressure tests and trip tests

List the components inspected at each ITM interval (weekly, monthly, quarterly, annual) and the acceptance criteria for each

Explain the difference between an impairment and a deficiency and the required response for each

Walk through the annual main drain flow test and calculate expected flow from the orifice and static pressure

Explain trip testing, alarm test, and valve status testing for dry-pipe and preaction systems

Diagnose common failure signatures: low pressure, slow trip, false alarms, and obstructed heads

Describe the process for restoring a system after an impairment and who must be notified

Map Maryland's licensing structure for sprinkler contractors, designers, and fitters and identify which license covers which work

Outline the plan review and permit submission process including which authority has jurisdiction

Identify the state-adopted code edition and explain how local amendments affect design and installation

Explain contractor and individual continuing education and renewal requirements

Apply Maryland-specific code provisions to two design scenarios and note where state rules tighten the model code

Explain the roles of the state fire marshal, local fire departments, and building officials in approvals and inspections

Review record-keeping, as-built, and documentation obligations after installation

Re-work two missed design calculations from week 1 using the code edition in force in Maryland

Complete a full-length timed practice exam and score each domain separately

Review every missed question and write the underlying rule or calculation in your own words

Re-drill the two weakest domains with focused practice sets

Build a one-page formula and code-reference sheet from memory, then verify it against source material
