The V-2924A 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-2924A 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-2924A 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-2924A control units can be interconnected to allow global all call and global priority pages
for up to six (6) V-2924A control units.
