OVERVIEW
FEATURES AND CAPABILITIES
The FE-3S, Digital Page Stacker and Feedback Eliminator has 4 minutes of
available audio memory and can record up to 16 pages, each with a maximum
message length of one minute. While recording new messages, another set of
up to sixteen messages, can be playing back.
The FE-3S makes feedback over the paging system virtually impossible by opening the loop between the input microphone and the speakers. This eliminates
the potential for acoustic feedback while giving the user flexibility in the manner
in which pages are broadcast. To insure that messages are not played during a
time when other high volume noises might mask them, the systems ability to
stack pages permits a user supplied ambient noise level analysis computer to tell
the FE-3S to hold the messages and then play them when they can actually be
heard.
Multiple Record and Playback modes are supported as well as Pre-page Tones,
Adjustable Delay Between Messages and Message Repeat functions. ABORT
and STOP functions are also available.
Transformer isolated 600 ohm Line input and Priority input, as well as trans former isolated switchable 8 ohm or 600 ohm audio output

OPERATION
3
There are three important functions that the FE-3S performs:
1. It eliminates feedback by recording the incoming page(s) then plays
it back.
2. It is able to repeat each page allowing for a better response in a
noisy environment.
3. It is capable of stacking up to 16 incoming pages by its ability to
Record incoming pages while Playing back previously recorded ones
on a first-in first-out basis.
Other important features such as the ability to Record/Regenerate, or Block
DTMF tones, used for zone selections, and a host of manual operation modes
that allow Page screening functions.
The FE-3S is designed to run in both Automatic and Manual modes. For paging
applications the Automatic mode is the most widely used. This mode requires
minimum installation time since it is the factory’s default setup. RJ12 connectors
are used for audio/Control inputs and outputs. Where logical, certain control signals are provided on the individual RJ12 connectors associated with each.
AUTOMATIC OPERATION
There are several methods to initiate the record mode on the FE-3S. The activation mode will be selected upon power up. It cannot be changed during normal
operation. The record mode will be selected via user configuration dip switch.
These modes are listed and described below.
Loop Start, 2 Wire - The FE-3S will source the talk battery to the ring and tip,
sense the loop current and start the recording process for the duration of the
Dry Loop, 4 Wire - or contact activation mode. A separate switch closure provided to the FE-3S record input will put the unit into the Record mode for the
duration of the contact closure. This mode is available regardless of any other
mode selection.
Audio Activation - The FE-3S will start recording when the audio sensor goes
active and will stop when the audio sensor is inactive for three seconds.
DTMF Activation - For dry loop mode without a separate switch closure and
perhaps noisy audio lines. The FE-3S will start recording when it “see’s” a valid
DTMF tone and will stop when the audio sensor is inactive for three seconds.
MANUAL OPERATION
Terminal Block, Input Controls
General pur pose I/O Ter minal blocks will be used for other control
Inputs/Outputs.
Record, Play, Stop, Priority and Abort
Five input control signals are offered to the user for complete control over the
recording and playback processes. None of these inputs are necessary for the
use of the FE-3S in Auto-play mode but may be required based on system
requirements.
All of the input controls are optically coupled so as to electrically isolate each
activation initiated via contact closure or open collector driver.

(RECORDING)
Page Recording
Upon receiving a valid recording signal, the FE-3S will start recording at the
beginning of the memory until the page is complete. While this page is playing, if
a new page is requested it will be recorded. Multiple pages will be recorded in
series until the playing message has completed it’s play routine. If, for any reason, the end of available recording memory is reached, the system will immediately stop recording, and a Busy back tone will be sent back through the audio
source signaling the user that the FE-3S is not available. Any message prematurely cut off because the end of memory was reached will not be played. If the
memory is filled and a new recording command is offered, the FE-3S will not go
into record mode and a busy back tone will be output to tell the user that the FE3S is not available.
Loop Start - The FE-3S will source “talk battery” onto the ring and tip lines. The
FE-3S will sense loop current flow and start the recording process for the duration of the loop current flow.
The recording is limited to one minute per page and a maximum of three minutes
per stack, or reaching the end of memory during the recording. The incomplete
recorded page will not be played.
There are two conditions which will cause the FE-3S not to respond to a
RECORD command.
1. If the end of memory has been previously reached on a page the
FE-3S will not allow another page to be attempted.
2. If 16 messages have already been recorded without being played
back. The FE-3S cannot record more than 16 messages into the
mode.
NOTE: A user configuration will be provided which will cause the FE-3S to
ABORT a recording should 8 seconds of silence be presented during a recording. Once the FE-3S senses 8 seconds of silence it will offer the busy back tone
to the user and abort the recording. The FE-3S will not be able to record new
pages for as long as the Record input is held active. The user will be informed
that their page has been aborted, prompting them to hang up. This mode is not
defeatable.
RECORD Input
The Record input will be used for the Dry Contact activation method. A maintained contact closure will be necessary at this input to keep the FE-3S in record
mode. Once the contact is closed the FE-3S will commence recording the audio
input immediately. When the contact is opened (released) the unit will immediately stop recording. The recorded message must be a minimum of one second
in length. Any message shorter than this will be deleted.
12
Page Playback
Manual mode is used in applications where the FE-3S may not be the only
device feeding the PA system. In this mode the FE-3S will record, or stack, up to
sixteen messages into memory, waiting for a “Play” activation from an external
controller. Upon this contact, all of the stacked pages are played in a first-in, first
out fashion from memory. Since the unit has two memory banks (hence the
Record while playing feature), it is possible to record up to 32 messages, only in
manual mode when only Record commands are initiated without any Play commands.
In Manual mode after a recording sequence is completed and no page is currently playing, the FE-3S can begin playback of the previously recorded messages.
If the unit is currently playing, the FE-3S sequence through both sides of the
memory in seamless fashion.
Once a message has been stopped, either because the message was played, or
a manual STOP command was received, that message shall be tagged for overwrite. This means that messages cannot be stored and played repeatedly, or
skipped for playback later.
PLAY Input
If the FE-3S is in automatic playback mode, this input will have no effect. When
the FE-3S is in manual playback mode, this input will be necessary in order to
playback the messages once they are recorded. A momentary contact closure
will initiate the play sequence. A second play contact closure, while the FE-3S is
playing, will be ignored. A maintained contact closure will essentially put the FE3S into automatic repeat mode. Message strings cannot be repeated by using
the Play input after the string has already played.
STOP Input
Messages being played can be skipped and stopped using this input. A momen tary contact closure will cause the message being played to be stopped and
dropped from queue. If there is a message in the playing queue it will be played
next.
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. The recording process will not be affected.
If the STOP is maintained, The FE-3S will stop the currently playing message
and will wait for the stop input to go away before starting the next message, if
there is one in the stack. At this point the FE-3S will not be capable of playing
while this STOP input is held active.
13
PRIORITY Input
A PRIORITY bypass input which, when activated, system will halt the play
sequence to allow a separate audio input from Priority RJ12 connector, to be
routed directly through the FE-3S. The activation for this input must be maintained for the amount of time which the dedicated Priority audio input is to be
routed directly through the system. As soon as the activation is released, the
message play sequence, including the previously interrupted message, will
resume, after a one second delay.
NOTE: Normal system recording can be performed while the device is in the priority bypass mode.
ABORT Input
When the ABORT input is activated, the message which is being recorded will be
immediately halted and the busy back tone sent to at the audio input. The
recorded data will not be played as part of the playback message string. An
example of the use of this would be the security guard monitoring the pages, and
upon hearing an unauthorized page, aborting it. The busy back tone will be output for as long as this input is held active.
NOTE: The ABORT input has no effect on the playing sequence.
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. Although each of the relays have form C contacts, an internal jumper is made available to the user to route either the normally
closed or normally open to the output terminal block.
Power Applied - Green LED. This LED will be activated for the duration which
power is applied to the FE-3S.
Recording Output - Form A contact closure. This relay will be active whenever
the FE-3S is in the actual recording process. It will not be activated just because
the Record input is active, but only when the FE-3S is actually storing data.
Play Output. - Form A Contact closure relay will be active while the FE-3S is
Playing audio through the output. It will be active during the pause between the
message repeats but not during the delays between different messages within
the play sequence. The Playing output will be held active when the priority input
is active.
In-Use Output - Form A contact closure. Whenever the FE-3S is in some
process required by the user, this output will be active. This would include the
record and play processes, pauses, delays, record access tones, etc..
Other Output Signals
Busy Back Tone - A busy back tone tells a prospective user that the FE-3S is not
ready to accept the recording. This Busy Back tone will be in the form of a Busy
signal and will be output for the duration which the FE-3S can not record.
14
SETTING CONFIGURATION SWITCHES
The FE-3S is designed to have several functions programmed by the user.
These adjustments will be made via dip switch settings in the field. These pro grammable settings are listed and described below.

control purposes. A repeated page should not 3
have the zone control tones on the front end
of the second page because the zone control- Off*
ler is already routed, therefore these tones will On
be stripped on the repeat of a page. Unit
