<p>PROBLEM TO BE SOLVED: To provide sprinkler fire-extinguishing equipment capable of detecting which sprinkler head is actuated and causing a water pressurization/feed device to feed water at appropriate pressure according to an installation position of the actuated sprinkler head.SOLUTION: The sprinkler fire-extinguishing equipment includes an ultrasonic sensor providing a sprinkler-head unwinding pipe with address information so as to detect flowing water in the unwinding pipe. Further, the sprinkler fire-extinguishing equipment employs the water pressurization/feed device capable of arbitrarily controlling a feed water pressure. The ultrasonic sensor transmits own address information along with a flowing water detection signal. A pump control board, upon receiving them, controls the feed water pressure according to the position of the actuated sprinkler head.</p> |
