Abstract
A paging system controller is accessible from a plurality of input devices, such as an attendant's position, a telephone interface, telephone night bell, programmable switch devices and digital data communications devices, and is user-programmable to respond to signalling activity sourced from such accessing devices to establish a paging connection to and perform prescribed audio/visual output paging signal functions with respect to one or a plurality of paging zones served by the system. The output paging signal functions include the transmission of audio tone and voice paging signals via an audio signal path from a paging source to one or more controllably energized paging loudspeaker amplifiers, the generation of one or more alert tones to a paging zone, talkback audio signalling from the paging zone to a telephone interface, the playback of prerecorded (audio/visual) messages from either or both of audio output (e.g. loudspeaker) and visual output (e.g. silent radio) devices. Respective access inputs to which the paging system controller responds are given user-programmable priorities of access permission, with a higher priority access input always being given preference over a…
