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.

Abstract: A sprinkler including a housing having an outlet aperture covered by a shut-off valve, a heat-sensitive destructible element, and an actuation monitoring device. The monitoring device is configured as a current-conducting coating that is applied to a surface of the element. The coating has terminals for connecting to a circuit of a sprinkler status monitoring unit. The element is configured as a hermetic glass bulb filled with a liquid that boils at a sprinkler activation temperature. The terminals are located at one end of the heat-sensitive destructible element and are connected to the coating using clamps that encircle the surface of the element. The coating is applied to the surface using sputter deposition. The applied coating is electrically conductive and allows the bulb to be heated to a boiling temperature of the liquid with which the bulb is filled, while feeding voltage from the sprinkler status monitoring unit.
