C. Security Code
The Security Code is used to access the programming mode (see Programming section A) using only the numbers 0
- 9 in the security code. The factory set security code is “845464” and should be changed after installation to assure
security.
To change the security code, enter programming (see Programming section A), then enter the desired digits followed
by “#02”. Two beeps will be heard to confirm that the security code has been successfully changed.
D. Messages
The DVA-TNT comes from the factory with two sets of factory-recorded pre-time and temperature messages, a “Good
Morning/Afternoon/Evening” message and a “Thank You for Calling” message. You may select one of these two options
or record your own pre-time and temperature message (see section E).
1. Good Morning/Afternoon/Evening Message
This message is selected by entering “,4” while in programming. There
are three separate greetings that are automatically selected depending
on the time of day (see chart to the right).
2. Thank You for Calling Message
The greeting, “Thank you for calling”, can be selected by entering “,5” while programming.

a. Connect the LINE INPUT jack or terminals to an incoming phone line or analog station.
b. Call the C.O. line or analog PABX/KSU station connected to the DVA-TNT.
c. If the DVA-TNT is in the ring-trip mode, it will answer on the first ring. If the DVA-TNT is in drum recorder mode,
it will allow the line to continue ringing until the current message cycle has been completed, at which time it will
answer and produce a single beep as a user prompt.
d. Enter a ,followed by the six digit security code (see section Cbelow).
e. Two beeps will be heard indicating that the unit has entered programming.
2. Remote Programming

F. Time of Day
The DVA-TNT uses a standard 12-hour clock and will announce the time as such. When the DVA-TNT is first pow-
ered up, or it has experienced a loss of power longer than the back-up battery could maintain, the time of day will need
to be set.
Note: If the time of day is not set, the DVA-TNT will skip the time portion of the announcement. The DVA-TNT cannot
play a “good morning/afternoon/evening” greeting until the time is set. If the time is not set, the DVA-TNT defaults to
the “thank you for calling” greeting.
1. Enter programming (see Programming section A).
2. Enter two digits pertaining to the hour (01 - 12).
3. Enter the minutes (00 - 59).
4. The next digit signifies morning or afternoon, enter 0for AM or 1for PM.
5. Then enter “#01” to store the information.
Note: To prevent the DVA-TNT from announcing the time of day, enter “#01” without any preceding digits.
E. User-Recorded Messages
This message can be up to 30 seconds long and is played before the time and temperature is given, in place of the
“Good Morning/Afternoon/Evening” message or the “Thank You for Calling” message. To enable this message, enter
,,8while in programming, and to disable, enter ,,7. Follow these steps to record the pre-time and temperature
announcement:
a. Enter ,1while in programming.
b. The DVA-TNT will play “record your message now” followed by a single beep as a prompt to begin recording.
c. When finished recording, enter any touch tone to stop the recording.
d. The DVA-TNT will then playback the message just recorded. To listen to the message again, enter ,3, and the
DVA-TNT will then playback all user-recorded messages in the following order: the night message (if recorded),
the pre-time and temperature message (if recorded) and the post-time and temperature message (if recorded).
Note: If the available time is exceeded while recording, the DVA-TNT will automatically stop the recording process
and begin playing back the message just recorded.
1. Pre-Time and Temperature Message
This message can be up to 30 seconds long and is played after the time and temperature is given. After this mes-
sage is played, the DVA-TNT disconnects if in the ring-trip mode or starts a new message cycle if in the drum
recorder mode. To enable this message, enter ,,0while in programming, and to disable, enter ,,9. Follow these
steps to record the post-time and temperature announcement:
a. Enter ,2while in programming.
b. Follow steps b-d shown in section 1above.
Note: If the available time is exceeded while recording, the DVA-TNT will automatically stop the recording process
and begin playing back the message just recorded.
2. Post-Time and Temperature Message
The night message can be up to 15 seconds long and is played before the time and temperature is given. After the
time and temperature is given, the DVA-TNT disconnects if in the ring-trip mode or starts a new message cycle if in
the drum recorder mode. To enable this message, provide a contact closure across the “NIGHT MODE C.C. INPUT”
(terminals 7 and 8) on the front of the unit. Follow these steps to record the night announcement:
a. Enter ,0while in programming.
b. Follow steps b-d shown in section 1above.
Note: If the available time is exceeded while recording, the DVA-TNT will automatically stop the recording process
and begin playing back the message just recorded.
3. Night Message
G. Call Counter
The DVA-TNT has a call counter that can be read and reset by entering the programming mode. The call counter
capacity is 99,999 calls. To read the call counter, enter ,8while in programming. The DVA-TNT will play “total calls”
and then speak the individual digits making up the call count number. For example, “one, one, eight, nine” would
indicate that the call count was 1,189. The call counter can be reset by entering ,9while in programming. The DVA-
TNT will reset the call counter to zero and play “call counter has been reset.” Note: The call counter is volatile and
will be reset to zero when the unit is powered down.

H. Slave Mode
For ring-trip applications where heavy usage of the DVA-TNT is expected, multiple units may be configured in master-
slave mode to allow for multi-line capability without having to install additional temperature sensors for each DVA-TNT.
1. Since many PABX’s can be programmed to play a message from a single DVA-TNT to several callers at once, you
should determine if a multi-line installation is necessary.
2. Connect the temperature probe to the master unit (pins 9 and 10).
3. Program each unit individually to your desired messages and settings.
4. Connect the I/O communications terminal (pins 5 and 6) of the slaves in parallel to pins 5 and 6 of the master, being
careful to observe polarity.
5. Access the programming mode (see Programming section A) of the master and enter ,,1.
6. Access the programming mode (see Programming section A) of the slaves and enter ,,2.
7. Assign the master unit to the first line in your hunt group. This is important, as the slave’s temperature data will
only be updated when the master unit receives a call.
8. Attach the slave units to the subsequent lines in your hunt group.

The DVA-TNT can be set up in several modes of operation, including a time and temperature announcer, a time only
announcer, a temperature only announcer, a standard ring trip announcer, a drum recorder, as well as a night mode
announcer. The normal operating mode is for the main greeting to be given followed by “The time is XX:XX temperature
XX”. This basic operation can be customized in Programming.

C. Temperature Only Announcer
In some monitoring applications, it may be desirable to only announce the temperature. To set the DVA-TNT into this
mode, do not set the time of day. If the time of day is not set after a power up, the DVA-TNT will omit this portion of the
announcement. If recorded, an additional 30 seconds of voice recording may be used after the temperature message.
E. Drum Recorder
If the drum recorder mode is selected, the message will be repeated continuously. At the end of the message, an end
of message pulse will be sent out of the “Busy” terminal positions and the DVA-TNT will start a new message cycle. If
normal busy lead polarity is selected, the busy lead terminals will be open during the message and close during the
end of message pulse. If inverted busy lead polarity is selected, the busy lead terminals will be closed during the mes-
sage and open during the end of message pulse.
B. Time Only Announcer
If it is difficult to provide wiring for the temperature sensor, or you choose not to announce the temperature, the DVA-
TNT can be used as a time only announcer. If no temperature sensor is detected, the DVA-TNT will automatically elim-
inate the temperature announcement. In this mode the DVA-TNT will send out the selected greeting or custom record-
ed greeting followed by the time of day. If recorded, an additional 30 seconds of voice recording may be used after the
time message.
D. Standard Ring-Trip Announcer
If no temperature sensor is connected, and the time is not set, the DVA-TNT will act as a simple announcer. When the
unit is called, it will play the selected greeting, or the custom recorded greeting and hang up. If recorded, an addition-
al 30 seconds of voice recording may be used after the message.
F. Night Mode Announcer
If the night mode is activated via a contact closure across the night mode terminal 7 and 8, the DVA-TNT will play the
night message and then the time and temperature. If configured for ring-trip, the unit will then hang-up. If configured
for the drum recorder, the unit will start a new message cycle.
