GLOSSARY OF TERMS

The V-2924 Talkback Intercom System provides 24 stations with one-way, two-way, group call and all call pages.
Each station can be programmed for one-way or two-way communication.  The stations may be grouped into one-
way page groups.  The system also provides the ability for a remote speaker location equipped with a call button to
call the attendant location.  The attendant receives calling speaker identification when using a Caller ID equipped
telephone or a Caller ID display.

The V-2924 is compatible with standard 45 ohm speakers and one-way amplified speakers and can be accessed via a
single line phone, E-Key line port or PABX loop start trunk port.   An RS-232 port on the control unit provides a
connection for a serial printer for printout of system activity.

The V-2924 provides a background music input and is designed to automatically mute music during a page.  The
basic system also provides four (4) contact closures associated with the last 4 zones to allow for door strike plate
activation.  Multiple V-2924 control units can be interconnected to allow global all call and global priority pages for
up to six (6) V-2924 control units.
