Preface
In this manual, the family of the DV-100 and DV-EM VoiceLink products are referred to as the Series DV-100.
The Series DV-100 provides playback capability for pre-recorded messages. The Series DV-100 does not sense an emergency
condition or hazardous fires, but is only a part of a system that does sense such conditions. The Series DV-100, when activated by
a control panel, provides a pre-recorded tone and/or voice message to an audio system. When used as part of a protective
signaling system, the Series DV-100 must be properly connected to a compatible control panel that has been approved by a
nationally recognized testing laboratory ("LISTED") and/or a LISTED compatible audio system with LISTED compatible notification
appliances for proper operation.
PERSONNEL PROPERLY QUALIFIED IN THE APPLICATION AND USE OF LIFE SAFETY EQUIPMENT ("QUALIFIED

Introduction
Wheelock's VoiceLink products provide unique digital recording, programming, storage, and playback capabilities to create versatile
and automated announcement systems. Figure 1 illustrates the basic capabilities of the Series DV-100.
The Series DV-100 plays pre-recorded voice, tones, or other sounds through amplification equipment (not supplied with the Series
DV-100) when instructed to do so by a contact closure or an instruction over a serial link from other equipment. Custom recording
and programming can be provided by Wheelock or by the system installer using a Series DV-200 record/playback model to program
a Series DV-100 playback model.
This manual describes the Series DV-100 which features:
•
A PREPROGRAMMED SERIES DV-100 MUST BE PROPERLY INSTALLED AND CONNECTED TO A COMPATIBLE CONTROL
PANEL AND AUDIO SYSTEM, AND A POWER SUPPLY, TO FUNCTION IN A VOICE ANNOUNCEMENT SYSTEM. THE
SERIES DV-100 OPERATES ONLY WITH REGULATED AND FILTERED DC VOLTAGE, NOT FULL-WAVE-RECTIFIED
VOLTAGE.
The control panel can range from simple push-buttons or detectors that provide contact closures to activate Series DV-100 files to
sophisticated, computer-based control panels that address Series DV-100 files through a serial port. Similarly, the audio system can
range from a simple amplified speaker to a large, multi-channel audio distribution system that may also be integrated with a zoned
telephone paging system. Wheelock offers a wide line of audio equipment to configure such systems.
Wheelock models; DV-100, DV-200, MDV-2, DX-100, DX-200, MDX-2 and DV-EM are UL 864 approved for use with Fire Alarm
Control Panels (FACP). The above models are used as accessory control units in UL 864 listed protective signaling systems. All
models have an operating voltage range of 11.0-29.0VDC. All are operated by a serial port or contact closure with an adjustable
output from 0.5-2.0VRMS.

Message Memory
Wheelock's Series DV-100 is a playback-only unit and has no recording capability. The Series DV-100 is programmed by first
recording messages in a Series DV-200 and then transferring the information to the Series DV-100.
NOTE:
When programming a Series DV-100 from a Series DV-200, refer to the Series DV-200 operation and installation manual for
required procedures, cautions and warnings.
The Series DV-100 has the ability to store up to eight minutes of audio. The audio is stored digitally on up to eight memory
integrated circuit ("I.C.") chips. Each memory I.C. can store up to one minute of audio messages. See Figure 8 for the socket
locations S63 thru S70 on the Series DV-100 printed circuit board into which the eight memory I.C.'s, U63 thru U70 are inserted.
The eight memory I.C.'s which store audio data are U63 thru U70. These memory I.C.'s are commonly referred to as erasable
programmable read only memories ("EPROM's", see EPROM definition in glossary.). The number of memory I.C.'s in this Series
DV-100 will vary between one and eight, depending on the number and length of audio messages recorded.
EPROM's are erased by exposure to ultraviolet ("UV") light. UV light is present in light sources such as sunlight and fluorescent
lamps. An EPROM must be protected against accidental or premature erasure by covering its window
(see Figure 2) with a UV opaque label.
Each EPROM supplied with this module has its window covered with a UV opaque label. An EPROM's label is to be removed only
erasing the EPROM. After an EPROM has been erased, its window must be recovered with a new UV opaque label.
when
WARNING: EACH EPROM MUST HAVE A UV OPAQUE LABEL PLACED IN PROPER POSITION AS SHOWN IN
FIGURE 2. IF THE LABEL IS WORN, TORN, OR OTHERWISE DAMAGED IN ANY WAY THAT WOULD
ALLOW UV LIGHT TO PASS THROUGH, STORED MESSAGES CAN BE ERASED. IF STORED
MESSAGES ARE ERASED, THEY WILL NOT BE DELIVERED WHEN AND WHERE REQUIRED, AND
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

Input and Output Options
Each Series DV-100 model includes 8 inputs that can be used to activate file numbers 1 through 8 with a contact closure or a
transistor switch across the corresponding input terminals. The optional digital voice expansion modules (“DV-EM”) can provide 32
inputs. When a DV-EM is used, the 8 inputs in the Series DV-100 unit cannot be used. Up to 8 Series DV-EM’s can be connected
to a Series DV-100 for a total of 256 inputs.
Make sure that Series DV-100 outputs are connected to a properly operating, listed compatible audio system so that message files
assigned to that channel can be played.
The Series DV-100 is provided with a serial port, through which up to 999 files can be activated with digital commands. The contact
inputs in the Series DV-100 or Series DV-EM modules can be used along with the serial port. A command is required to start a
message, and a second command is required to stop the message. The operation is similar to closing an input contact (start) and
then reopening the contact (stop).
Up to four audio output channels are available with the Series DV-100. The audio output from each channel of the Series DV-100 is
through a 600 Ohm transformer and is designed to drive a load impedance of 600 Ohms or higher. The audio level of each channel
can be adjusted by a potentiometer on the PC board from -3.8 dBm to +8.2 dBm (0.5 to 2.0 Vrms). All Series DV-100 output
channels can be active simultaneously.
Message Files
All messages are stored in files within the Series DV-100 memory. Up to 999 message files can be stored. There is no limit on the
length of a message file (except for the limit imposed by total memory in the unit). There are two types of message files: voice files
and string files. Voice files are created by storing audio directly into the selected file number. String files are created by storing file
numbers of other message files into the selected file number. (See "file" and "string" definitions in glossary.) Each message file
must be assigned a priority level from 1 to 5 (1 is highest, 5 is lowest) and an output channel from 1 to 4. See “Output Channels”,
“File Priority”, and “Playing Files” sections for additional information.
WARNING: EACH MESSAGE MUST BE ASSIGNED ITS INTENDED OUTPUT CHANNEL AND PRIORITY LEVEL
String files reduce the message memory requirements by allowing many different message files to be created with a relatively small
library of voice files that contain custom words or phrases and using one or more of the six string file commands. The string file
commands are ADD, PAUSE, COMMON REPEAT, FILE REPEAT, TELEPHONE, and END. ADD is used to add a previously
created message file to the string. PAUSE is used to add a period of silence to the string. COMMON REPEAT is used to play the
next entered file number multiple times. FILE REPEAT is used to play the entire file again a specified number of times after the file
has been de-activated. TELEPHONE is used to add telephone numbers to a string file. END is used to finalize the string.
The following is an example of creating string files from a small library of voice files using the ADD command.
The following voice messages are recorded into the indicated file numbers:
“There is a fire on the” into file number 100
“First” into file number 101
“Second” into file number 102
“Third” into file number 103
“Floor” into file number 104
Create three string files as indicated:
File 1: ADD 100, ADD 101, ADD 104, END
File 2: ADD 100, ADD 102, ADD 104, END
File 3: ADD 100, ADD 103, ADD 104, END
DURING PROGRAMMING OR THE MESSAGE WILL NOT BE PLAYED WHEN AND WHERE REQUIRED.
THIS COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR
OTHERS.
DV-100 Manual Sheet 11 of 37
Rev. G August 2000
When file number 1 is selected to play, “There is a fire on the first floor” will be played. When file number 2 is selected to play,
“There is a fire on the second floor” will be played. When file number 3 is selected to play, “There is a fire on the third floor” will be
played.
The following is an example of creating string files using the ADD command and the PAUSE command.
The following voice messages are recorded into the indicated file numbers:
“Welcome to Herbie’s” into file number 100
“Our fish are the freshest in town” into file number 101
Create a string file as follows:
File 1: ADD 100, PAUSE 10 seconds, ADD 101, END
When file number 1 is selected to play, “Welcome to Herbie’s”......(10 seconds of silence)......”Our fish are the freshest in town” will
be played.
The following is an example of creating string files using the ADD command and the COMMON REPEAT command.
The following voice messages are recorded into the indicated file numbers:
“Run” into file number 100
“to the nearest salesman” into file number 101
Create a string file as follows:
File 1: COMMON REPEAT 3 times, file number 100, ADD 101, END
When file number 1 is selected to play, “Run, Run, Run to the nearest salesman” will be played.
The following is an example of creating string files using the ADD command and the FILE REPEAT command.
The following voice message is recorded into the indicated file number:
“Thank you for buying Wheelock voice products” into file number 100
Create a string file as follows:
File 1: ADD 100, FILE REPEAT 3 times
When file number 1 is selected to play, “Thank you for buying Wheelock voice products” will be played. The file will play
continuously as long as the file is activated. After the file is de-activated, the file will play three additional times. A momentary
activation will play the message four times. The FILE REPEAT command must be the last item in the string.
The following is an example of creating string files using the ADD command and the TELEPHONE command.
The following voice message is recorded into the indicated file number:
“A fire has been detected at 101 Main Street” into file number 100
Create a string file as follows:
File 1: TELEPHONE 555-0100, TELEPHONE 555-1212
TELEPHONE 555-4949, ADD 100, END
When file number 1 is selected to play, the phone number 555-0100 is called. If the line is busy or the call is unanswered, the
phone number will be tried two more times. After the third attempt, the next number in the string file is called. If three attempts to
that number fail, the next number in the string file is called, and so on. If the last phone number in the string file also fails three
times, the process starts over with the first phone number.
If at any point the called phone number is answered, the message “A fire has been detected at 101 Main Street” is played. Within
30 seconds of the end of the message, the digital voice module expects to hear an acknowledge code from the person receiving the
message. If the acknowledge code is not received, the digital voice module treats the call the same as a line busy or an
unanswered call. The acknowledge code expected is a “1-2-3” dialed from a touch-tone phone. When the acknowledge code is
received, the digital voice terminates the file, and no other calls are made.
The TELEPHONE command is only available to use in string files programmed for channel 1 with no secondary channels.
TELEPHONE commands must be the first commands entered into the string. Once any other command has been selected when
creating a string file, the TELEPHONE command is prohibited from being used.
