GLOSSARY OF TERMS 16

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.
