Fire Sprinkler Design Course

Lesson 1 • Fire Behavior and Suppression Principles

Covers combustion chemistry, fire growth stages, and heat release rates. Establishes the physical basis for why sprinkler systems are effective suppression tools.

Lesson 2 • Key Components and Their Functions

Identifies sprinkler heads, control valves, alarm devices, and piping assemblies. Component knowledge underpins all subsequent hydraulic and layout design work.

Lesson 3 • Regulatory Framework and Standards Overview

Surveys the role of fire protection standards, authority having jurisdiction, and code adoption processes. Provides context for design decisions made throughout the course.

Lesson 1 • Occupancy Classification Systems

Explains light, ordinary, and extra hazard occupancy groups and their defining characteristics. Classification directly determines water demand and sprinkler spacing limits.

Lesson 2 • Commodity Classification for Storage

Covers Class I through IV commodities and plastics classification for storage occupancies. Accurate commodity classification drives rack storage and in-rack sprinkler decisions.

Lesson 3 • Selecting Design Criteria from Hazard Data

Translates hazard analysis findings into density-area design curves and system selection. Students produce a written design basis statement for a sample occupancy.

Lesson 1 • Conducting and Interpreting Flow Tests

Details hydrant flow test procedures, data recording, and pitot gauge use. Flow test data forms the empirical foundation for all hydraulic calculations.

Lesson 2 • Identifying and Resolving Supply Deficiencies

Addresses low-pressure, low-flow, and unreliable supply scenarios and their remedies. Students specify fire pumps or storage tanks to meet design demand.

Lesson 3 • Plotting the Water Supply Curve

Teaches the N^1.85 method for plotting available water supply on a hydraulic graph. Students overlay demand curves to verify system adequacy visually.

Lesson 1 • Software-Assisted Hydraulic Calculations

Introduces industry-standard hydraulic calculation software workflows and output verification. Students cross-check software results against hand calculations to ensure accuracy.

Lesson 2 • Hydraulic Principles Review

Covers Bernoulli's equation, friction loss, and velocity pressure concepts as applied to pipe flow. These principles are the mathematical engine behind all sprinkler calculations.

Lesson 3 • Hydraulic Calculation Procedures

Walks through the step-by-step hydraulic calculation worksheet for the most demanding design area. Students balance loops, account for elevation, and determine inlet pressure.

Lesson 4 • Calculation Quality Control and Submission

Covers peer review checklists, calculation report formatting, and submittal requirements. Proper documentation ensures regulatory acceptance and field accuracy.

Lesson 1 • Ceiling and Roof Geometry Considerations

Addresses sloped ceilings, peaked roofs, and irregular ceiling configurations affecting sprinkler placement. Students adjust layouts to maintain required deflector-to-ceiling distances.

Lesson 2 • Special Occupancy Layout Requirements

Applies layout rules for high-piled storage, attics, concealed spaces, and high-rise buildings. Each special condition introduces unique placement and system type requirements.

Lesson 3 • Drafting and Reviewing Sprinkler Plans

Teaches plan drawing conventions, symbol standards, and self-review techniques for sprinkler layouts. Accurate plans reduce field errors and accelerate permit approval.

Lesson 4 • Sprinkler Coverage Area Rules

Details maximum and minimum spacing limits for standard, extended coverage, and residential sprinklers. Coverage rules vary by hazard and ceiling type, requiring careful selection.

Lesson 1 • Piping Materials and Joining Methods

Compares steel, CPVC, copper, and listed flexible piping for sprinkler applications. Material selection affects cost, installation speed, and environmental suitability.

Lesson 2 • Valves, Drains, and Auxiliary Components

Details control valve placement, drain sizing, inspector's test connections, and pressure gauges. Auxiliary components enable safe testing, maintenance, and emergency isolation.

Lesson 3 • Hangers, Supports, and Seismic Bracing

Specifies hanger types, spacing intervals, and seismic brace requirements for sprinkler piping. Proper support prevents pipe movement that could cause joint failure or misalignment.

Lesson 4 • Pipe Routing and Coordination

Covers routing strategies to minimise friction loss, avoid conflicts, and simplify installation. Coordination with mechanical, electrical, and structural trades prevents costly rework.

Lesson 1 • High-Piled and Rack Storage Systems

Covers ceiling and in-rack sprinkler design for high-piled storage exceeding standard height limits. Students size in-rack systems and determine required water demand for storage configurations.

Lesson 2 • Gaseous and Clean Agent Systems

Covers total flooding clean agent and carbon dioxide systems for sensitive equipment protection. Students calculate agent quantity, enclosure integrity, and discharge time requirements.

Lesson 3 • Foam-Water Sprinkler Systems

Introduces foam concentrate types, proportioning methods, and foam-water system configurations. Foam systems are required for flammable liquid hazards where water alone is insufficient.

Lesson 4 • Water Mist Systems

Explains water mist suppression mechanisms, nozzle classifications, and system design parameters. Mist systems suit spaces where water volume must be minimised, such as machinery rooms.

Lesson 1 • Hydrostatic and Flush Testing

Details hydrostatic pressure test procedures, duration requirements, and acceptable leakage criteria. Flushing removes debris that could obstruct sprinkler orifices and impair system performance.

Lesson 2 • Authority Having Jurisdiction Inspection

Prepares designers and contractors for the formal regulatory inspection process and common findings. Understanding inspector expectations reduces delays and costly re-inspections.

Lesson 3 • Pre-Acceptance Inspection Procedures

Covers contractor pre-inspection checklists, visual inspection criteria, and punch list development. Thorough pre-inspection reduces failures during the formal authority having jurisdiction review.

Lesson 4 • Operational and Alarm Testing

Covers inspector's test valve operation, alarm device verification, and flow switch testing. Operational tests confirm that water flow triggers correct alarm and supervisory signals.
