NOTES

  • This subclass covers also means for identifying or incapacitating burglars or the like.
  • This subclass does not cover:
    • the mere provision of an audible or visible signalling device on measuring or switching apparatus;
    • alarm systems for indicating that a specific variable has exceeded, or fallen below, a predetermined value, which are covered by the relevant subclasses of class G01 for the measurement of that variable.
    • alarms for specific processes or types of machines or apparatus, which are covered by the relevant subclasses for the processes, machines, or apparatus.
  • In this subclass, the following term is used with the meaning indicated:
    • "systems" may cover also devices peculiar thereto.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
