The VC-24 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 oneway 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 VC-24 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 VC-24 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 VC-24 control units can be interconnected to allow global all call and global priority pages for up to six (6) VC-24 control units.

COMMUNICATING WITH THE VC-24

Communicating with the VC-24 allows sending and receiving of user programmed data, Setting of System Date and Time, and reading the revision numbers of the system firmware.

Once system programming is complete, this data must be downloaded to the VC-24 System. This communication can be accomplished through two methods:

Initiating Communications

Direct Connect (PC is on site with the VC-24 System - can be accessed via RS232 cable). To Connect: Connect cable from the VC-24 to the PC being used. Set up Com Port (see Set Up Com Port Section). Connection complete.

Modem Connect (PC is off site or can only be accessed using phone lines to communicate). To Connect: Set up modem (See VCMDM user manual). Set up Com Port (See Set Up Com Port Section). Select Dialing Method

• Modem Connect

One-Way Page with Meet Me/Follow Me

Attendant makes an all call or group page to locate a specific individual -

• Called person presses call button two times at

any talkback speaker (this cancels the page to all other speakers and connects the attendant to the answering speaker)

• Called person presses the call button of another

speaker included in the original page two times, the call is disconnected from the active speaker and reconnected at the new speaker.

• Handsfree alert tone notifies the attendant and

speaker location the Meet Me or Follow Me was successful.

Allows the use of a single line phone (“A” lead modified). When the phone goes offhook, all handsfree, group, and/or all call pages are cancelled and the phone is connected to the attendant.

Override Page Port

When a phone connected to the override page port goes offhook, it is immediately connected to all speakers for a one-way page. Any existing handsfree or one-way pages will be placed at the top of the queue for reconnection when the priority phone releases. The attendant phone receives a repeat beep tone alerting of an override.

Queue Operation Attendant phone is in use and another call is placed from a speaker location, the phone and connected speakers receive a queued call tone (single or triple beep tone), and the call is placed in the queue. Pressing the “#” key twice while on a call with one or more queued calls, will disconnect the current call and connect the attendant to the next call in the queue. If the attendant hangs up while calls are in the queue, the phone will ring and the next call in the queue will be connected when the phone is answered. Queued calls will be accessed in the order received with a maximum of 20 calls being in the queue at one time. If the queue is full, additional calls are ignored unless the last queued call has a lower priority than the incoming call in which case the lower priority call will be replaced in the last position by the new call.
