GENERAL DESCRIPTION
This device interfaces a two wire (POTS) telephone service with control switching and
modulator input for an EAS system.
It allows the user to determine how many rings will occur before the telephone line is
seized.
It allows the user to determine if he wishes to have the unit hang up after a pre-determined time, or if he wishes it to look for the line current interuption (WINK) on the telephone line to effect a disconnect.
A custom message, of up to 20 seconds, may be input by the operator. The message,
when entered, should be followed by a short silent period so that the unit can more
easily detect the DTMF control tones. When the telepnone line detects a ring signal,
and after the number of rings selected by the user occur, the line is siezed.
The unit then begins playing back the message stored by the operator, and looks for a
series of DTMF tones corresponding to the three digit access code.
Upon the telephone caller entering the three number access code - selected via jumpers by the operator - the unit will cease playing the message and proceed to the next
stage of operation.
The device will then connect the telephone audio to the input to the modulator, allowing
the telephone caller to speak over the EAS system.
Also after the access code has been entered, relays will actuate. The relay is SPST,
and all the contacts are available on the screw terminals of the connector.
The unit will continue to allow the operator to speak over the EAS system until one of
two things happen:
The unit times out if the time out option has been set.
The caller hangs up.
Power is supplied from a 12 VDC plug mounted supply.

Audio Connection:
Telephone audio is available at Pins “5” and “E” (ace FIGURE 1 page 6). This is a bi-directional
audio port balanced with a source impedance of 600Ω_. The maximum audio level that should be
introduced at this point is -9dBm,
Auxiliary Relay Contact Connection:
The Form C relay contacts are available at the edge connector. This relay energizes (closes) when
the Model 3137B “answers” the incoming call and dc—energizes (opens) when it disconnects,
PIN 10 - COMMON TERMINAL OF SPDT RELAY
PIN K - NORMALLY CLOSED CONTACT OF RELAY
PIN L - NORMALLY OPEN CONTACT OF RELAY
Holding Relay Connection:
The holding relay output is intended to drive an external 12 VDC relay whenever the coupler is in the
“OFF-HOOK” state, Pin “9” will go to a high logic state (+12 VDC) on answering (referenced to Pin
“7”, and will return to a low logic state on disconnect (see FIGURE 1 page 4).
Set Input Connection:
Momentarily grounding Pin “1” forces the 3137B to connect to the telephone line without an incoming
call or if held at ground after the 3137B has answered an incoming call keeps it from disconnecting
by means of CFR or timeout,
Hold Input Connection:
Grounding input Pin “A” will not allow the 3137B to seize the telephone line but will keep the on board
timer from running thus preventing timeout disconnect until Pin “A” is released from ground. Once
released from ground the on board timer starts timing out, and will disconnect the 3l37B according to
the preprogrammed time.
Control Input Connection:
Applying +12 VDC to Pin “D” will cause the 3137B to seize the telephone line and not release it until
the +12 VDC is removed. When in this state the reset input Pin “4” will not override the control input
Pin “D” controlling the line seize relay.
Reset Input Connection:
Momentarily grounding Pin “4” causes the 3137B to disconnect or if held at ground will prevent the
3137B from answering an incoming call, Grounding this input overrides all other 3l37B functions
except Pin “D”.
Supply Input Connection:
The power supply input is connected to Pins “8” (+12VDC) and “3” (circuit common). Consult
FIGURE 1 page 6.

Answer Time:
A jumper must be installed at one of the nine positions of ~J1~ to cause the device to automatically
answer an incoming telephone call. As such, these nine positions permit the user to select from one
to nine ring,~ before answer.
10
NOTE:
The device will answer after the number of selected rings. For example, if two rings before
answer has been selected then the device will go to the OFF-HOOK state at the end of the
second ring.
The simulated ring signal heard by the calling party may not accurately reflect the actual ring
timing being delivered to the called station.
Disconnect Time:
A jumper must be installed at one of the nine positions of ~‘J2~ to cause disconnection after a fixed
period of time. This has been set at the factory to provide approximately time increments of six seconds for each of the nine positions. As such, placing the jumper at J2 position 1 causes disconnection after 6 seconds, placing the jumper at J2 position 2 causes disconnection after 12 seconds, etc.
This permits a selection of incremental times up to 54 seconds (nominal). If longer OFF-HOOK times
are required, potentiometer Rl4 can be adjusted in the clockwise direction. A maximum time of
135 seconds (nominal) is achieved when this potentiometer is in the full clockwise position.
If disconnection on a fixed time basis is not desired then no jumper should be installed in one of the
J2 positions.
CAUTIONARY
NOTE: If no jumper is installed in one of the J2 positions then some other means of disconnect
should be employed to guarantee disconnect. This may be either external reset from a
controlling device or by detection of loop battery interruption.
Disconnection upon detection of loop current interruption (J4) and disconnection by fixed time-out
(J2) may both be selected. In this circumstance the device will disconnect according to whichever
signal occurs first.
Disconnection Upon Detection of Loop Current Interruption
Jumper J4 is used to select disconnection upon detection of a loop current interruption from the
Central Office.
This is a two-position jumper and the jumper must be installed iun one of the two available positions.
Failure to place the jumper in one of the two available positions may result in improper operation of
the device.
Jumper J4 must be installed in the position as described in FIGURE 1 for disconnection upon detection of loop current interruption or else it must be installed in the alternate position as described in
FIGURE 1 if disconnection upon detection of loop current interruption is NOT desired.
11
Disconnection upon detection of loop current interruption (J4) end disconnection by fixed time-out
(J2) may both be selected. In this circumstance the device will disconnect according to whichever
occurs first.
Answer/Signal Mode Selection:
Jumper J3 is installed and should remain installed for normal operation of this device. Jumper J3
should be removed only if an external device iM to control answer and disconnect.
Jumper J3 can be removed to cause the device not to answer an incoming call. In this circumstance
the answering device will close the auxiliary hook switch contact after the number of rings before
answer (as selected by jumper Ji) to signal an external device of the incoming call but will not terminate the telephone line (go OFF-HOOK).
An external control device would instruct the Unattended Answering Device to answer the incoming
call by taking the control line (3137B card edge Pin ~D’) to ~V (nominally +12 VDC).
The external control device would maintain this control line at +V until it wanted to be disconnected
from the telephone line. It would then remove the i-V from the control input of the Unattended Answering Device. The Unattended Answering Device would disconnect from the telephone line immediately
upon release of the control line by the external control device.
Disconnection upon loop current interruption by the Central Office should also be selected on J4 for
proper resetting of the Unattended Answering Device in this mode.
OPERATION
The device will answer an incoming call after the number 0± rings prescribed by J1 and complete a
bi-directional audio path between the telephone line and the non-network audio port.
It will remain on the line until the calling party disconnects and a loop battery interruption is given to the
called party or until it times out as prescribed by jumper programming.
THEORY OF OPERATION
A ring signal is applied to the telephone line by the Central Office.
This signal is passed from the telephone line to the ring detector circuit, A1, on the 3137B. A1 demodulates the envelope of the ring signal and passes each ring through PC1 and A2B to the ring
counter, A3.
The counter is advanced each time a ring is detected from the telephone line.
The selected output of this counter (corresponding to the number of rings before answer) is passed
through J1 to a latch, A4, which is then SET.
12
The SET condition at this latch causes Ki to energize by way of A2C, J3 and Q3. This seizes the
telephone line.
At the same time the setting of latch A4 operates K1, it also enables the disconnect oscillator, A2D.
A2D generates a clock pulse to the counter A6 which is advanced with each pulse from the oscillator.
The selected output of this counter is a reset pulse that passes through A5C, CR9 and A2E to reset
the ring counter, A3 and the latch A4. Resetting the latch A4 causes K1 to be dc-energized (releasing
the telephone line) and the disconnect time oscillator, A2D to be disabled and the disconnect time
counter is reset via A5D.
If disconnection upon loop current interruption is selected then telephone loop current illuminates PC2
after K1 energizes.
When the current interruption is detected from the Central Office then the transistor of PC2 is turned
OFF. This serves as a reset signal which is passed through A5B and CR8 to reset the system as in
the circumstance of the reset on disconnect timer time-out.
13
Dial Tone Disconnect Option:
For telephone exchanges where the Central Office does not provide a current interruption on the
calling party disconnect, return of dial tone can be used to force disconnect of the Model 3137B.
Model 90417:
An optional Model 90417 Dial Tone Detector module may be added to the 3137B for detection of
continuous dial tone. The 90417 replaces the A2 IC. plugging directly into A2’a socket and connecting two wires to J5. After detecting continuous dial tone the 90417 module will reset the 3137B.
Interconnecting Two Telephone Lines:
Two 3137B’s can be used to interconnect two telephone lines, permitting the user to call in on one
line and DTMF dial out on the second line. The dial tone disconnect option is recommended when
using this configuration to provide reliable disconnect upon return of dial tone from either direction.
Where the combined telephone line loss are too great a bi-directional amplifier may be required. The
amplifier may be placed on either of the two lines on the telephone line side of the 3137B.
14
Interconnecting Four Wires To The Telephone Line:
The 3147-1 Hybrid Coupling Network can be used to interconnect four wire circuits to a standard
telephone line. The 3147-1 provides telephone line impedance balance, isolation and signal separation for interconnections to separate four wire transmitter and receiver circuits to a two wire bi—
directional audio path. This audio path, when connected to the 3137B, provides an interconnect to a
standard telephone line.
Telephone Access of Audio:
The Model 3185E Dual Tone Decoder can be used to provide a telephone access code. As shown
below a access code must be entered after the 3137B answers the telephone line to complete a bi—
directional audio path. If wired as shown, the access decoder will reset when the 3137B disconnects
from the telephone line providing maximum security.

INSTALLATION/DIAGRAMS/SETUP
The 3567 is designed to plug into a Monroe model 985A EBS Telephone Coupler.
The DTMF audio input level from the 600 ohm transformer on the 3137B is adjustable. Normal
position
is in the center of it’s range. Generally, problems arise if the level into the DTMFÒ decoder are
too high.
The code sequence is defaulted to ‘911’ if all three pin pairs on jumper J1 are open.
Refer to the chart in the 985A manual for settings for other sequences. These would only
be used if the other sequence has been compromised.
To record a message on the unit, remove the top cover, and supply power to the 985A.
While pushing SW1, the small black push-button switch, and with your mouth from 6 to 10
inches from the small microphone, speak in a normal level, clear voice as you wish the message
to be
replayed. When you are finished, release the switch.
When calling the unit, the message will automatically play back continuously, until the proper
DTMFÒ sequence has been received.
