NE Fire Sprinkler study plan

List the components of a wet-pipe, dry-pipe, preaction, and deluge system and state the activation sequence for each from memory

Identify the applicable NFPA 13 occupancy hazard classifications (light, ordinary group 1 and 2, extra hazard group 1 and 2) and assign three building examples to each

Define the key hydraulic terms (flow, pressure, density, discharge coefficient, K-factor, friction loss) and write the formula relating discharge to pressure and K-factor

Map the exam's single content domain into a personal topic checklist covering design, installation, hydraulics, inspection, and ITM

Calculate required flow from design density times design area for at least five practice scenarios

Trace a simple tree and gridded layout and explain how remote-area selection and hydraulic balance differ between them

Compute friction loss through schedule 40 steel pipe using the Hazen-Williams form and verify units on each step

Explain how K-factor, minimum operating pressure, and sprinkler spacing interact to set the minimum end-head pressure

Size a water supply by converting a static and residual flow test into an available-pressure-versus-flow curve

Determine the margin between supply and demand at the base of the riser and at the most remote head

Select sprinkler temperature ratings and response types (quick, standard, special) for given occupancy and ceiling conditions

Identify obstruction rules that require additional sprinklers or shielding, and describe the spacing rule for each case

Explain the purpose and required components of a fire department connection, main drain, and flow test valve

Describe the acceptance test sequence for a new system: hydrostatic, flow, main drain, alarm, and trip tests for dry and preaction systems

State the inspection, testing, and maintenance frequencies for gauges, alarm devices, valves, and waterflow switches

Differentiate between impairment procedures, hot work controls, and the conditions that require a fire watch
