This lot of RTS 848 stations have working speakers and mics, but many are missing button caps, need relamping, and ALL of them are being sold strictly AS IS. No testing has been done beyond applying power and checking the front panel lamps. Most of these will need some work.
Cosmetically they are in good condition.
Power supply is NOT Included, sold separately.
The Model 8488 is an intercommunications master station. Each 848A is a station in a point-to-point intercom system which can have as few as 2 stations or as many as 24 stations -- forming a full 24 by 24 station system. Any configuration of multiple stations in this system is called a matrix. In the matrix, up to 12 conversations may be in progress at any time, either separately or in groups. Each 848A station has two built-in conference-line intercom channels that can be used separately or as part of an RTS Systems TWIntercomSystem. Eachstationalsocontainsan ALL TALK button for paging throughout the entire system.
The Model 848A is an audio communication station with 24 station channels and 2 conference-line intercom channels. Operating in a Cwire, full- duplex mode, all communicationpathsaredistributed toeachstation. Thisconcepteliminatestheneedfor central matrix switching electronics -- all station- select switching is done directly at each station.
Each talk path is dedicated to a send/receive bus. In a typical operating example, a user chooses the station he wishes to talk to by pushing that station's pushbutton. The selected station will automatically hear the calling station. No other station will hear this message unless they are assigned the same receive address or more than - one station has been selected by the sender.
