G08B - Definition 
Definition statement
This subclass covers:
Signalling systems, either characterised by the form of transmission of the signal or by the nature of the signal, e.g. audible, visible, tactile or a combination of these
Personal calling systems, e.g. audible, visible, tactile or a combination of these
Order telegraphs
Alarm systems, e.g. burglar alarms, fire alarms, alarms responsive to multiple conditions, including transmission of alarm information between substations and a central station
Predictive alarm systems
Identifying, scaring or incapacitating burglars, thieves or intruders
Checking or monitoring of signalling systems, personal calling systems or alarms systems, including prevention or correction of operating errors
Relationship between large subject matter areas
The mere presence of a signalling step in a process covered in another subclass is not a sufficient criterion to select a classification symbol from this subclass. For example, a measuring or switching apparatus with an audible or visible signalling device is covered in the classification place relevant to that measuring or switching apparatus. A specific example would be G01D 1/18, which covers measuring arrangements for signalling that a predetermined value of an unspecified parameter has been exceeded.
Many subclasses provide for an alarm operating in connection with their subject matter. For example, a measuring apparatus may use an alarm system to indicate that a specific variable has exceeded, or fallen below, a predetermined value. This aspect is covered in the subclass covering that specific variable. Similarly, alarm systems forming part of a specific process, apparatus or machine are covered in the classification place covering that specific process, apparatus or machine.
