SPRINKLER WITH ACTIVATION MONITORING

The proposed invention relates to sprinklers in fire-extinguishing installations and is intended for feeding fire-extinguishing liquid into a source of fire in the case of combustion or burning. The essence of the proposed invention consists in a sprinkler containing a housing having an outlet aperture, which is covered by a shut-off valve, a heat-sensitive destructible element and an activation monitoring device; the activation monitoring device is in the form of a currentconducting coating which is applied to the surface of the heat-sensitive destructible element, the coating having outputs for connecting to a circuit of a sprinkler status monitoring unit. Preferable variants of the sprinkler involve the heat-sensitive destructible element taking the form of a hermetic glass bulb filled with a liquid which boils at a sprinkler activation temperature; outputs for connecting to a circuit of a sprinkler status monitoring and control unit are connected to the coating by means of clamps which encircle the surface of the element; the current-conducting coating is applied to the surface of the element by means of sputter deposition; the outputs are disposed on one end of the element; the applied coating is electrically conductive, allowing the bulb to be heated to the boiling temperature of the liquid with which the bulb is filled, while feeding voltage from the monitoring and control unit.
