Overview
Features and Capabilities
The Digital Feedback Terminator has 4 minutes of available audio memory and can record up to 16 paging
messages. A single page can have a maximum length of 1 minute. The unit can record new pages while
playing back previously recorded pages.
The DFT120 eliminates feedback over the paging system by opening the loop between the input microphone
and the speakers. This not only eliminates the potential for acoustic feedback, but also gives the user
flexibility in the manner in which pages are broadcast.
Multiple Record and Playback options are supported, as well as Pre-Page Tones, Message Repeat, and
Adjustable Delay Between Message Repeats functions. Abort and Stop functions are also available.
The DFT120 includes a transformer-isolated 600-ohm page input and priority override input, as well as a
transformer-isolated switchable 8-ohm or 600-ohm audio output.

Package of two 1/2" mounting wood screws
Installation Manual
You can mount the Digital Feedback Terminator on a wall, rack or table.
Installation Steps
These are the general steps for installation:
1.
2.
3.
4.
5.
Mount the unit to the wall, rack or table.
Make cable connections from the DFT120 to the PBX and the paging system.
Set DIP switches to the desired operation.
Power unit up.
Test unit operation.
Mounting the Unit
To mount the unit:
1. Select a space on the wall, rack or table. Make sure there is a standard electrical outlet into which you
can plug your power pack. This outlet should not be controlled by a switch.
2. Mount the DFT120 and its wiring at least 18 inches away from power supply or other equipment that
generate electrical noise. Secure using the supplied mounting screws.
3. Connect the power supply. Power LED should be green.
6
Operation
There are three important functions that the Digital Feedback Terminator performs:
1. It eliminates feedback by recording the incoming page, then playing it back.
2. It is able to repeat a page once, allowing for a better response in noisy environments.
3. It is capable of stacking up to 16 incoming pages by recording incoming pages while playing back
previously recorded pages, on a first-in, first-out basis.
Other important features include the ability to record or block DTMF tones used for zone selections and
external control of system playback.
The DFT120 is designed to run either automatically or through external controls. For most paging applications, the DFT120 will run automatically. This configuration requires minimum installation time since it is the
factory's default setup. RJ11 connectors are used for Audio/Control inputs and outputs. Where logical,
certain control signals will be provided on the individual RJ11 connectors associated with each.
Page Operation
Recording a Page
A combination of the Page In interface switch and setup switches 1 & 2 determine how the DFT120 records
a page. The DFT120 is always monitoring for loop current or contact closure, depending on the Page In
switch setting. By configuring setup switches 1 & 2, the DFT120 can be configured to start recording a page
into memory only on loop current detection or only on contact closure detection. It can also be configured to
detect either of the above and then wait before recording a page into memory until a DTMF digit is detected.
This configuration provides for excellent DTMF signaling into a zone paging device.
For telephone systems that cannot provide a loop start or a contact closure, the DFT120 can be triggered
solely by audio detection. In this configuration when audio is detected the unit begins recording the page into
memory. After a 3-second interval of silence, the DFT120 stores the page and begins playback of the page
as soon as it is possible.
Loop Start Interface (Page In switch set to LS)
• Loop Start Activation
• DTMF Activation
(Setup switch settings UP, UP) - Begins recording page into memory as
soon as loop current is detected.
(Setup switch settings DN, UP) - Begins recording page into memory
when loop current is detected and then a DTMF tone is detected. This
provides for better DTMF signaling to zone paging devices.
Dry Audio with Contact Closure Interface (Page In switch set to DL)
• Contact Closure Activation
(Setup switch settings DN, DN) - Begins recording page into memory as
soon as a contact closure is detected.
• DTMF Activation
(Setup switch settings DN, UP) - Begins recording page into memory
when a contact closure is detected and then a DTMF tone is detected.
This provides for better DTMF signaling to zone paging devices
Dry Audio without Contact Closure Interface (Page In switch set to DL)
• Voice Activation
(Setup switch settings UP, DN) - The page is recorded into memory as
soon as audio is detected. After a 3-second interval of silence, the page
is completed and stored for playback.
If either the memory capacity (240 seconds) or the maximum number of paging messages stored (16) is
exceeded, no further page recording can occur. A busy back tone will be heard by the caller when the unit is
accessed under either of these conditions. The recorded message must be a minimum of one second in
length. Any message shorter than one second will be deleted.
7
Playing Back a Page
The DFT120 can be configured to either automatically play back a recorded page announcement or to store
recorded pages until directed to begin playing back these pages by some external device. The Play control
on the I/O connector and setup switch 8 "Play Mode" control the method of playback. Selecting Automatic
allows the DFT120 to operate without external signaling. Selecting Manual requires external triggering of
page playback.
The manual type of operation is sometimes necessary when the DFT120 is not the only device feeding the
PA system. With this type of operation the unit will record and save up to 16 pages until playback is triggered,
at which time all stored pages will be played in the order in which they were received. Once played, the
messages are erased from memory. When the DFT120 has 16 messages stored or if all available memory
has been used, it will issue a busy back tone whenever it is accessed until additional message space is
made available by playing the stored pages.
Override Operation
The DFT120 includes an override input that has priority over pages made through the Page In input. The
override input is a live input and does not record the page for playback at a later time, therefore it does not
protect the override input from feedback.
When an override page is detected either through loop start or contact closure signaling, the current recorded
page being played is immediately stopped and the override signal is sent to the Audio Out connector, and
thus to the PA system. After the override page is complete, the page that was interrupted is played again
from its beginning followed by all subsequently recorded pages. During an override, the DFT120 can
continue to record pages from the Page In input, however if the maximum number of pages stored or total
memory time is exceeded, then the unit will produce a busy back tone at the page input until previously
recorded pages are played.

DTMF Stripping
DTMF tones recorded at the beginning of an audio message are typically used for zone control purposes.
A repeated page should not have the zone control tones on the front end of the second page because the
zone controller is already routed, therefore these tones will be stripped on any repeats of a page. Only DTMF
tones at the beginning of the page would be handled in this fashion. Any DTMF tones recorded in the
middle of the message would be recorded and played back in the typical manner.

DTMF Control
This setting determines how and where the DTMF tones coming from audio input, during a recording, are

DTMF Allotment
This prevents unauthorized users from playing touch tones over the paging system. Most paging systems
require a limited number of tones to be recorded because of zone controlling equipment, but if a certain
number of tones is exceeded, the DFT120 will abort that particular recording. The number of tones which
the DFT120 can be programmed to cut off after is two, three, four, or unlimited.

This would allow the caller to abort a page directly. Should they not like the page they are recording, they
can press the “#” button two times within one second and the recording will immediately be aborted and the
busy back tone sent to the input. They can then call back and record another page. A single “#” sign during
the recording will not have any effect.

External I/O Connections and Control
Five control inputs (Record, Play, Stop, Override, and Abort) are offered to the user for complete control over
the recording and playback processes. None of these inputs are necessary when the DFT120 is operating
automatically (setup switch 8, UP), but may be required based on system requirements. All of the control
inputs are optically coupled so as to electrically isolate each activation initiated via contact closure or open
collector driver.
Abort Control Input
The Abort input is used to prevent a message from being recorded. It does not abort the playback of messages. To stop the playback of a message, see Stop Control Input. See Message Abort in the Setting Setup
Switches section.
When the Abort input is activated, the message that is being recorded will be immediately halted and the
busy back tone sent to the audio input. The recorded message will not be played as part of the playback
message sequence. This causes the user to be cut off and prevents the page from being broadcast. The
busy back tone will be output for as long as this input is held active.
Override Control Input
An Override bypass input which, when activated, stops the play sequence in order to allow a separate audio
input from Priority RJ11 connector to be routed directly through the DFT120. The play sequence, when
allowed to resume, will continue to play back a sequence from the beginning of the message it was playing
when the Override (Emergency) bypass input became active.
The activation for this input must be maintained for the amount of time that the dedicated Override audio
input is to be routed directly through the system. As soon as the activation is released, the message play
sequence will resume, after a one second delay. Normal system recording can still be performed during an
override condition.
Stop Control Input
Messages being played can be skipped using this input. A momentary contact closure will cause the message being played to be stopped and the next message to be played. Once a message has been stopped
using this command, the message is canceled and cannot be played back at a later time.
The Stop command will have no effect on the operation of the record process. If the unit is recording at the
same time it is playing, a Stop command will only stop the currently playing message.
If the Stop control is maintained, the DFT120 will stop the currently playing message and will wait for the
Stop input to be removed before starting the next message if there is one in the stack. Eventually the recording stack will be filled with messages preventing the system from recording new messages. At this point, the
DFT120 will not record nor would it be capable of playing while this Stop control is held active.
Play Control Input
If the Play Mode DIP switch 8 is set to automatic, then this input will have no effect.
When the Play Mode DIP switch 8 is set to manual, the DFT120 is configured for manual/external playback
control. Operating this input will be necessary in order to play back the messages once they are recorded.
A momentary contact closure will initiate the play sequence of all messages currently in memory. A second
play contact closure, while the DFT120 is playing, will initiate the playback for all messages in memory (new
and old) since the last play activation. A maintained contact closure will essentially configure the DFT120 for
automatic playback. Messages cannot be repeated by using the Play control after the sequence has already
been played. Play contacts (pins 2 and 5) of the RJ11 jack and the I/O terminal block (pins 9 and 10) are
internally connected.
Page In Control Input
The Page In input is used for the Dry Audio with Contact Closure activation method. Once the contact closure is closed, the DFT120 may commence recording depending on the DIP switch 1 and 2 settings. A maintained contact closure will be necessary at this input to keep the DFT120 recording. When the contact is
opened, the unit will immediately stop recording. The recorded message must be a minimum of one second
in length. Any message shorter than one second will be deleted. Page In contacts pins 2 and 5 of the RJ11
jack and the I/O terminal block (pins 6 and 1) are internally connected.
Note: Once the DFT120 senses 8 seconds of silence, it will send the busy back tone to the user and abort
the recording. The DFT120 will not be able to record new pages as long as the Page In input is held active.
The user will be informed by the busy back tone that the page has been aborted, prompting them to hang
up. This feature is not defeatable.
13
Terminal Block, Output Signals
All status outputs will be provided via relay contact closure. These contact closures will be provided via
terminal block to the user. The name and description of each output is shown below.
Busy Contact
Normally Open contact closure becomes shorted whenever the DFT120 is processing a page. This would
include the record and play processes, repeats and delays, recording playback tones, etc.
Play Contact
Normally Open contact closure becomes shorted whenever the DFT120 is playing audio through the output.
It will be shorted during the pause between the message repeats but not during the delays between different messages within the play sequence. The Play output will be shorted when the Override Input is active.
Rec Contact
Normally Open contact closure becomes shorted whenever the DFT120 is actually recording a page into
memory. It will not be activated just because the Record input is active, but only when the DFT120 is
actually storing data.
14
Example: System Setup and Connecting to the Paging System
The DFT120 can be configured in several ways depending on the paging system used. The DFT120 is
typically installed between the telephone system and the paging system. It interfaces with the paging
controller in a zone paging environment, and with the amplifier in a single-zone installation.
