    Abstract - (Show below) - (Hide below)

    Specifies specific requirements for pumpset systems to be used with fixed fire protection installation such as fire sprinkler, fire hydrant, fire hose reel and fire protection water spray systems.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for pumpset systems, generally represented by the equipment contained in Figures 3.4 and 3.5, for use with fixed fire protection installations such as sprinkler, hydrant, water spray, and hose reel systems. It covers water supplies and specific requirements for pumps, drivers, fire pump controllers, and auxiliary equipment. Requirements for installation and acceptance testing for electrical and compression-ignition drivers are also included.NOTE:Some special fire pump installations, e.g., at petrochemical and petroleum plants and small rural installations may require variations from the requirements of this Standard.
