Partyline: What is the current version of the MS-812A Main Station?

The MS-812 Intercom station is a 12 channel fully programmable micro-processor controlled Master station intended to work with other Clear-Com Party-Line products. All aspects of the station operation are under micro-processor control with many operational parameters programmable by the user.

An LCD display is used to assist the user in programming. The user programmed functions are saved in Non-Volatile memory (EEPROM Memory) and are retained during power-down.
The MS-812 directly supports Clear-Com's IFB and ISO systems. Up to eight channels of IFB can be controlled directly by the existing front panel buttons.

The MS-812 directly replaces the use of an AX-4 or MA-4 in a PIC-4000 based system. Up to sixteen channels of Clear-Com ISO-4000 can be controlled directly by existing front panel buttons eliminating the need for external ICP-4 control modules.
The internal power supply is intended to operate only the internal circuitry of one unit and requires connection to 120/240 VAC 50/60 Hz.

The external Intercom system will need a standard Clear-Com power supply.
A portion of the rear panel is removable offering the user several options on type of system interconnection. The standard version of the MS-812 is shipped with 12 XLR connectors for CC intercom lines with line termination jumpers
available from the rear of the unit. Another version with 8 XLR connectors for CC intercom lines with line termination jumpers is also available. 
The MS-812A data sheet is attached below.

The MS812 is now obsolete and there is no direct replacement

  • Alternative options are RSC2700 in conjunction with MS-704's or a Helixnet digital partyline system
