SIGNALLING SYSTEMS, e.g. PERSONAL CALLING SYSTEMS; ORDER TELEGRAPHS; ALARM SYSTEMS

Description

G08B covers signalling and alarm systems for communication, notification, and emergency response purposes. The classification encompasses personal calling systems (such as intercoms and paging devices), order telegraphs for transmitting commands or instructions, and alarm systems designed to alert users to hazardous conditions or security breaches. Technologies in this subclass include fire alarms, burglar alarms, personal emergency devices, and related detection and transmission mechanisms that generate signals to inform or warn recipients of specific events.

G08B 1/00 Systems for signalling characterised solely by the form of transmission of the signal
G08B 13/00 Burglar, theft or intruder alarms
G08B 15/00 Identifying, scaring or incapacitating burglars, thieves or intruders, e.g. by explosives
G08B 17/00 Fire alarms; Alarms responsive to explosion
G08B 19/00 Alarms responsive to two or more different undesired or abnormal conditions, e.g. burglary and fire, abnormal temperature and abnormal rate of flow
G08B 21/00 Alarms responsive to a single specified undesired or abnormal condition and not otherwise provided for
G08B 23/00 Alarms responsive to unspecified undesired or abnormal conditions
G08B 25/00 Alarm systems in which the location of the alarm condition is signalled to a central station, e.g. fire or police telegraphic systems
G08B 26/00 Alarm systems in which substations are interrogated in succession by a central station
G08B 27/00 Alarm systems in which the alarm condition is signalled from a central station to a plurality of substations
G08B 29/00 Checking or monitoring of signalling or alarm systems; Prevention or correction of operating errors, e.g. preventing unauthorised operation

G08B 7/00 Signalling systems according to two or more of groups G08B3/00 - G08B6/00
G08B 9/00 Order telegraph apparatus, i.e. means for transmitting one of a finite number of different orders at the discretion of the user, e.g. bridge to engine room orders in ships
