Abstract
A wet-pipe sprinkler system, method of supplying water to the system, and method of dealing with a leakage of the system are provided, wherein the wet-pipe sprinkler system includes a sprinkler head; a plurality of interconnected pipes for supplying water to the sprinkler head; at least one water supply connected to one end of the pipes; an electric main valve for controlling inflow of water to the pipes; an electric drain valve to drain water from the pipes; a first electrical control circuit in a central control studio which outputs a drain valve opening signal to the electric drain valve and a main valve closing signal to the electric main valve when a leakage is detected, thereby blocking the water from entering the pipes and draining the water from the pipes. Accordingly, a leak may be dealt with promptly, thereby minimizing damage caused by the leakage.
