PURPOSE: An automatic operating device for sprinklers is provided to enable rapid suppression of a fire by making all sprinklers operate at once thus minimizing victims and property damages. CONSTITUTION: The automatic operating device for sprinklers comprises a body(110) fixed to a fire-fighting solution supply pipe and having an injection port(111) at the lower side thereof, an injection plate(120) for allowing a fire-fighting solution to be uniformly injected in all directions, a heat-response valve(130) fixed between the body and the injection plate and adapted to seal the injection port of the body, and a heater installed adjacent to the valve for heating the valve. The valve has a glass tube(131) charged with alcohol. As the glass tube is broken by the temperature of the outside, the valve serves to open the port of the body.
