G08B SIGNALLING SYSTEMS, e.g. PERSONAL CALLING SYSTEMS; ORDER TELEGRAPHS; ALARM SYSTEMS
Introduced: September 1968
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.
