VOCIA DESK STATION 4 (DS-4)
The DS-4 is a desktop networked paging station for use in Vocia®systems. The DS-4 features embedded DSP and on-board memory
to support standard and advanced public address and mass notication functionalities. The DS-4 can store four user-congurable page
codes. Additionally, all device-specic conguration information is stored locally, which means the DS-4 does not rely on a centralized
controller for processing and page routing. Thus, the processing, routing and storage functionality in a Vocia® system is decentralized.
This eliminates the centralized point of failure and builds redundancy directly into the network. As part of the Vocia system, the DS-4
meets paging requirements for facilities of all sizes.

Setup and Use
The Vocia software provides an intuitive interface for conguration, DSP equalization, and programming of the DS-4. The information supplied
by this manual relates to physical connections and assignment. For more details on software setup, please consult the Vocia Help File.
Display
The DS-4 features a backlit display that provides the user with an easy-to-read interface to view paging information.
Microphone
The DS-4 microphone has a cardioid polar pattern. Correct operation of the microphone is essential for good speech intelligibility.
The recommended distance between the user’s mouth and the microphone is between 2 and 4 inches (50 and 100mm). Closer use may
cause distortion and unwanted bass boost, while more distant use may result in inadequate sound level. The microphone is a dynamic type
with two transducers. The primary (microphone) transducer is constantly monitored for ambient signal. In low ambient conditions, the
secondary transducer is energized with an inaudible tone to emulate ambient noise.
Soft Key Buttons
Two soft key buttons are located to the right of the display. In the default state they are used as “Next” and “Previous” buttons to browse through
the Page Codes assigned to the DS-4. If PIN security is enabled (see PIN Security section of this document for more information), the soft key
buttons are used to accept or cancel PIN entries. During a delayed page, the soft key buttons are used to cancel the delayed page if required.
Destination Buttons
Four buttons located below the display enable the user to select from one of four predetermined Page Codes. The destination buttons
are set up using the Vocia software. For stations that are PIN-enabled (see PIN Security section of this document for more information),
these buttons are also used for PIN entry.
Push-to-Talk Button
The Push-to-Talk (PTT) button, represented by the speaker icon, triggers the action associated with the selected Page Code
(generally a live page, delayed page, or recorded message).
Status LEDs
The status LEDs are located directly above the PTT button and inform the user of the current state of the paging station once the PTT
button is pressed. The left yellow LED “Wait” indicator illuminates while the system establishes audio paths, checks for zone availability,
and plays the chime (if selected). The right green LED “Please Talk Now” indicator illuminates once the DS-4 audio path is live.

DS-4 BOTTOM VIEW
Device ID
The rotary ID switches are located on the bottom of the DS-4 and give the unit a unique Device ID. The switches are in hexadecimal
format. All DS-4 units must have a unique Device ID to function within a Vocia Paging World (i.e., it is not possible to have two DS-4
units with the same Device ID of hex 07). To assign a Device ID of hex 07, turn the LSB switch to 7 and leave the MSB switch on 0.
To create an ID of hex B7, turn the LSB switch to 7 and turn the MSB switch to B. Device ID switches should be set using a 0.1 inch
(2.5mm) to 0.12 inch (3.0mm) flat blade screwdriver. More information on setting IDs and the hexadecimal numbering scheme used
in Vocia can be found in the Vocia Help File.
Please note: Changes made to the Device ID while connected to the network require a power cycle in order to take effect.
CobraNet
The DS-4 is a CobraNet device. All CobraNet routing and bundle assignments are processed by the Vocia devices locally. Vocia makes
dynamic use of available bundles in CobraNet. Vocia devices are currently not interoperable with non-Vocia devices.
Network Connection
The DS-4 has two RJ45 connectors located on the bottom of the unit that are labeled (1) Audio Network and (2) Option. The Audio Network
connector should be wired to standard copper Ethernet cable to interface the DS-4 to a Vocia system via a PoE-compliant network switch. The
Option connector is currently not used. The RJ45 connector provides two LEDs that indicate Ethernet link and network activity (see table
below).

DS-4 BOTTOM VIEW
This connection carries control data, power, and digital audio over CobraNet. PoE-enabled network switches or PoE midspan adapters
must be used to power the DS-4. These must be 802.3af compliant. The maximum distance between any unit and an Ethernet switch is
328 feet (100 meters) when using copper cabling. Additional Ethernet switches and/or ber-optic cable can be used to further extend
distances between units on a network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions) within
a network.
If other network trafc shares an Ethernet switch with the Vocia network, a managed switch should be used with separate VLANs.
The following diagrams illustrate valid network connections for the DS-4.
Personal Identication Number (PIN) Security
The DS-4 can be congured for PIN security protection. If PIN security is enabled via the Vocia software, the four Page Code buttons may
be used to enter the required four-digit PIN (see button labeling examples below). To enter a number, the user may need to press a button
multiple times (as in SMS messaging). During PIN entry, the two “Next” and “Previous” soft key buttons on the right side of the display will
display as “Clear” and “Enter” respectively. Input the four-digit PIN sequentially, followed by the “Enter” key or the Push-to-Talk button.
Each digit will be shown briey on the display and subsequently replaced by an asterisk for security purposes. If the entered PIN is correct,
the station will unlock and be ready for use.
After a period of inactivity (no pages made and no buttons pressed), the DS-4 will revert back to a locked state. This length of time
(at a default of 180 seconds) is set using the Vocia software. To lock the station instantly, the user can press and hold down the “Next”
and “Previous” buttons at the same time.

DS-4 DISPLAY
Display Status Messages
The following messages are used to display the state of the DS-4 during normal operation. More information on display status messages
can be found in the Vocia Help File.
1. Destination Idle: This status message indicates that the paging station is ready and there are no busy zones among
the destinations selected by the Page Code.
2. No Network: This status message indicates that the DS-4 is not connected to a functioning network.
Please check network connections and settings.
3. Destination Busy: This status message signies that at least one of the destination zones is busy with a lower priority page.
When paging into a busy zone, the lower priority message will be lost.
4. Destination Delay: This status message indicates that at least one of the destination zones is busy with a page of equal priority.
When paging into a busy zone at an equal priority, the message will be recorded in the DS-4 locally and played when the busy zones
become available.
5. Not Available: This status message indicates that the selected Page Code is not available. The message “Code Barred”
or “Undened” will appear in the top left corner of the display. Please choose a different Page Code or assign the selected
Page Code to the DS-4.
6. Please Wait: This status message signies that the PTT button has been pressed and the system is assigning paging resources
and playing the chime. Simultaneously, the yellow LED below the “Wait” icon will illuminate.
7. Request Failed: This indicates that the PTT button has been pressed and the request has failed. If a recorded message
is associated with this Page Code, please check that an MS-1 is online and congured to play the announcement.
8. Please Talk Now: This status message indicates that the PTT button has been pressed, the page has been correctly set up in the
system, any assigned chime has nished playing, and the audio path is open. This status message corresponds with the green LED
illuminated below the “Please Talk Now” icon.
9. Request Queued: This status message reports that the selected Page Code represents a request to play a recorded announcement.
When the zone(s) are ready to receive the announcement, the message will be played and the DS-4 will return to the Destination Idle state.
10. Cancel Request?: This status message indicates that the selected Page Code is a Delayed Release page. Once the PTT button
is released, the “Cancel” prompt will ash on the display. The “Cancel Request?” message is displayed for ve seconds. If the user
presses the Cancel button within this ve-second period, the recorded page will be discarded and the system will return to idle status.
If ve seconds elapses and the user does not press the Cancel button, the message will be released for playback as soon as all
destination zones are available.
