Notes

(1)

 This subclass covers also means for identifying or incapacitating burglars or the like.

(2)

 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 G 01 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.

(3)

 In this subclass, the following term is used with the meaning indicated:
 

-

 "systems" may cover also devices peculiar thereto.
