automatic sprinkler system
(2) The term “automatic sprinkler system” means an electronically supervised, integrated system of piping to which sprinklers are attached in a systematic pattern, and which, when activated by heat from a fire, will protect human lives by discharging water over the fire area, and by providing appropriate warning signals (to the extent such signals are required by Federal, State, or local laws or regulations) through the building’s fire alarm system.
