  • the sprinkler is also suitable for installation in walls or floors.
  • the sprinkler is also suitable for installation in ceiling panels and ceiling materials such as concrete.
  • the invention is suitable for making a concealed sprinkler from conventional sprinklers of different manufacturers.
  • Sprinklers in fire extinguishing systems are usually screwed to a pipe that protrudes through the ceiling of the corresponding room, so that the sprinkler can be triggered in the event of a fire on the object to be deleted and distributes the extinguishing liquid on the response of the trigger element on the fire.
  • the arrangement of sprinklers in workrooms such as laboratories, production facilities and warehouses is unproblematic, since these are functional areas in which such devices do not interfere.
  • sprinklers are also arranged in rooms with a selected aesthetic architecture in which they can have a disturbing effect. In this case, it is common to install the sprinkler completely or partially sunk into the ceiling, where it is still visible. In special cases, it is installed as a concealed sprinkler, that is, the sprinkler is embedded in the ceiling of the building and provided with a cover. For this purpose, a variety of solutions are known.
  • US 4,976,320 describes a concealed sprinkler whose cover is also removed by an ejector and via a spring.
  • the cover is a simple plate that is unlikely to cause much damage when dropped. Complicated, however, the mechanism is designed, which ensures that the cover is repelled by a spring.

  • the magnets may be one or more magnets.
  • the magnetic force on the hood of the sprinkler is designed so that the cover is removed by the escaping extinguishing agent.
  • a resilient element is arranged between the cover and the spray plate of the sprinkler that is stretched in the standby state by means of fusible link and relaxed at a predetermined temperature by desoldering and the relaxed spring by overcoming the adhesive forces of the magnets removed the cover.

  • the hidden sprinkler has the advantage that in the event that the fire heat passes from the top of the sprinkler, the sprinkler initially triggers and removed with magnets attached cover through the fire water and, if the fire heat from below reaches the sprinkler, the cover is removed by means of spring by the melting of the fused solder and the sprinkler can trigger faster than is the case with other sprinklers of this type.

Due to the escaping water falls Within a very short time the cover 4 from, so that the deletion can take place. This is especially important when fire heat from above. the sprinkler 2 passes.
