Standard for the Installation of Standpipe and Hose Systems. 2016 Edition (30 cards)
1.1.1 Scope of standard.
1.1.1 This standard covers the minimum requirements for the installation of standpipes and hose systems.
1.2 Purpose of standard.
1.2.1 The purpose of this standard is to provide a reasonable degree of protection for life and property from fire through installation requirements for standpipes and hose systems based on sound engineering principles, test data, and field experience.
3.3.1 Define Auxiliary Drain Connection.
3.3.1 A drain connection installed to permit draining water from a trapped section of pipe.
3.3.3.1.2 Define FDC for Manual Standpipe.
3.3.3.1.2 A connection through which the fire department can pump the primary water supply to a manual standpipe system at the required system demand.
3.3.4.1 Construction Types. Type I and II.
3.3.4.1 Those types in which the fire walls, structural elements, walls arches, floors, and roofs are approved noncombustible or limited-combustible materials.
3.3.4.2 Construction Types. Type III.
3.3.4.2 Those types in which exterior walls and structural elements that are portions of exterior walls are approved noncombustible or limited combustible materials in which fire walls, interior structural elements, walls, arches, floors, and roofs are entirely or partially of wood or smaller dimensions than required for Type IV construction or are of approved noncombustible, limited-combustible, or other approved combustible materials.
3.3.4.3 Construction Types. Type IV.
3.3.4.3 That type in which fire walls, exterior walls, and interior bearing walls and structural elements that are portions of such walls are of approved noncombustible or limited-combustible materials. Other constructed of solid or laminated wood or cross-laminated timber without concealed spaces within allowable dimensions of the building code.
3.3.4.4 Construction Types. Type V.
3.3.4.4 That type in which structural elements walls, arches, floors, and roofs are entirely or partially of wood or other approved material.
3.3.7 Define High-Rise Building.
3.3.7 A building where the floor of an occupiable story is greater than 75 ft above the lowest level of fire department vehicle access.
3.3.8 Define Hose Station.
3.3.8 A combination of a hose rack or reel, hose nozzle, hose, and hose connection.
3.3.9.1 Define Feed Main.
3.3.9.1 The portion of a standpipe system that supplies water to one or more standpipes.
3.3.9.1.1 Define Express Main.
3.3.9.1.1 The type of feed main supplying only the upper zone(s) of a standpipe system.
3.3.11.1 Define Nozzle Pressure.
3.3.11.1 Pressure required at the inlet of a nozzle to produce the desired water discharge characteristics.
3.3.1.1.2 Define Residual Pressure.
3.3.11.2 For standpipe systems, pressure acting on a point in the system with a flow being delivered.
3.3.11.3 Define Static Pressure.
3.3.11.3 For standpipe systems, pressure acting on a point in the system with no flow from the system.
3.3.12 Define Pressure Control Valve.
3.3.12 A pilot-operated pressure reducing valve designed for the purpose of reducing the down-stream water pressure to a specific value under both flowing and nonflowing conditions.
3.3.13 Define Pressure-Regulating Device.
- 3.13.1 Pressure-Reducing Valve is a valve designated for the purpose of reducing the downstream water pressure under both flowing and nonflowing conditions.
- 3.13.2 Pressure-Restricting Device is a valve or device designed for the purpose of reducing the downstream water pressure under flowing conditions only.
3.3.15 Define Record Drawing.
3.3.15 A design, working, drawing, or as-built drawing that is submitted as the final record of documentation for the project.
3.3.16 Define Standpipe.
3.3.16 The system piping that delivers the water supply for hose connections, and for sprinklers on combined systems, vertically from floor to floor.
3.3.16.1 Define Horizontal Standpipe.
3.3.16.1 The horizontal portion of the system piping that delivers the water supply for two or more hose connections, and for sprinklers on combined systems, on a single level.
3.3.17.1 Define Automatic Dry Standpipe System.
3.3.17.1 A standpipe system permanently attached to a water supply capable of supplying the system demand at all times, containing air or nitrogen under pressure, the release of which opens a dry pipe valve to allow water to flow into the piping system and out of the opened hose valve.
3.3.17.2 Define Automatic Wet Standpipe System.
3.3.17.2 A standpipe system containing water at all times that is attached to a water supply capable of supplying the system demand at all times and that requires no action other than opening a hose valve to provide water a hose connections.
3.3.17.3 Define Combined System.
A standpipe system that supplies both hose connections and automatic sprinklers.
3.3.17.4 Define Manual Dry Standpipe System.
3.3.17.4 A standpipe system with no permanently attached water supply that relies exclusively on the fire department connection to supply the system demand.
