Abstract: The invention relates to fire-extinguishing means, and more particularly to sprinklers for fire-extinguishing systems. A sprinkler comprises a body with an outlet opening which is closed off by a check valve, and a unit for controlling the state of the check valve. The sprinkler is provided with a fire sensor and an activation unit. The unit for controlling the state of the check valve is equipped with an electric trigger device. The input pins of the activation unit are connected to the outputs of the fire sensor. The output pins of the activation unit are connected to the outputs of the electric trigger. The technical result is an increase in the response speed of the sprinkler.
