6.5.9 Sprinkler/Standpipe System

Sprinklers will automatically suppress fire in the area upon sensing heat. Sprinkler activation will activate the fire alarm system. Standpipes have water available locally in large quantities for use by professional fire fighters. Multiple sprinkler and standpipe risers limit the possibility of an event severing all water supply available to fight a fire.

Redundant water services would increase the reliability of the source for sprinkler protection and fire suppression. Appropriate valving should be provided where services are combined.

Redundant fire pumps could be provided in remote locations. These pumps could rely on different sources, for example one electric pump supplied from the utility and/or emergency generator and a second diesel fuel source fire pump.

Diverse and separate routing of standpipe and sprinkler risers within hardened areas will enhance the system’s reliability (i.e., reinforced masonry walls at stair shafts containing standpipes).
