Revision Topics

The course will cover the following elements of basic sprinkler design:

Brief Introduction

• Design codes, rules & regulations

Principles of Design

• Definitions
• Tailoring a system to specific risk
• Classification of occupancies and fire hazards
• Discharge density
• Assumed maximum area of operation

This module identifies Hazard Classifications and with the use of an aide memoir, describes and catalogues basic design criteria including sprinkler performance demands, sprinkler sizes, maximum/minimum sprinkler spacing, areas of coverage, installation type limitations, water supply duration etc.

Sprinkler heads - types, uses and sensitivity

• Discharge patterns
• Temperature ratings
• Orifice/thread sizes and k-factors
• Types and sizes for various hazard classes
• Thermal sensitivity ratings and selection

Types of installation

• Wet alarm valve
• Dry alarm valve
• Alternate alarm valve
• Pre-action alarm valve
• Deluge valve

Points of discussion covered are basic operational principles and design of each type of valve, trimming details and periodic testing/changeover procedures.

Location and spacing of sprinklers

• Ceiling sprinkler spacing
• Sidewall sprinkler spacing
• Spacing from boundaries
• Location in relation to building structure
• Location in relation to building services
• Sprinklers above open ceilings

Included in this module are progressive exercises and examples to assist with principles of spacing, including beam, girder, truss and column rules.

Piping types and layouts

• Terminal distribution main layout
• Looped distribution main layout
• Gridded layout
• Methods of pipe sizing
• Material specifications
• Design, location and construction of supports

Pre-calculated method of pipe sizing

• Pipe sizing options
• Description of arrays
• Sizing range pipes
• Sizing distribution mains downstream of design points
• Sizing distribution mains upstream of design points
• Static gain

This module includes progressive exercises based predominantly on ordinary hazard design principles. High hazard variation is also incorporated.

Basic full calculation method of pipe sizing

This module introduces delegates to the Hazen-Williams formula for pressure loss calculation in pipework with working examples

Water Supplies

• Acceptable water supply sources
• Reliability and quality
• Towns main pressure and flow requirements and testing
• Water storage capacities and arrangements
• Suction and booster pumps
• Pumphouse arrangements
• Pump flow and pressure testing
