2-Way Talk-Thru
Electronic Communication System
A voice communications system for High-Security and Isolation
Booth Situations
Today’s security and isolation booths are often the best step you
can take to protect your employees. But do they protect or help
maintain your very important good will? Not if clerks and customers
have to shout and growl and repeat themselves to be heard or
understood.
Norcon’s Patented TTU-3 Talk-Thru Communicator is a 2-way,
hands-free audio system that provides high-quality personal
communication between people separated by security or isolation
barriers.
HOW IT WORKS …
The
Norcon
TTU
system
permits
hands-free,
2-way
communication between the booth attendant and the customer.
Unique circuitry facilitates ongoing, clear, 2-way conversation at all
times – as if the two parties were together in the same room.
The TTU-3 Talk-Thru Communicator now incorporates circuitry to
automatically attenuate the outside channel. If the gooseneck
microphone is not used for a period of 30 seconds, the outside
channel volume will be reduced approximately 70%. Normal
operation is restored as soon as the attendant speaks into the
gooseneck microphone. The automatic volume attenuation circuit
prevents outside noise from bothering the attendant.

The TTU-3 provides clear communication even in environments with
high ambient noise by shaping the sound for maximum intelligibility.
Its compression circuitry decreases loud, annoying sounds.
HOW TO INSTALL …
1. Mount the TTU unit using the method shown in
figure 1.
2. Remove the control panel from the prism-shaped
housing. The "Inside" unit houses the circuit board for
the system, the gooseneck microphone, volume
controls, power switch, power indicator LED and speaker.
The "Outside" unit has no electronics, a speaker and a
microphone is attached to the "Outside" unit.
3. Drill holes on the housing where required for
installation.
4. Snake the two pair cable (with connector on one end) FROM the
inside unit TO the outside unit. Make sure the connector is in the
inside unit. Attach the cable to the terminal block on the outside
unit, color to color. Connect shield to black wire. Join the
connector with the wire harness from the printed circuit board so
the colors line up.
5. For power connection, snakes the one pair cable (with the
connector on one end) FROM the inside unit TO the location of the
PS-1 Power supply. Connect the conductors to the power supply
(RED to +, BLACK to -). Plug the connector to its mate from the
printed circuit board.

6. The sound absorbing material in the housing may be
Removed during installation but should be replaced for normal
operation.
7. For best result separate inside and outside units as far as
Possible.

HOW TO USE THE TALK-THRU COMMUNICATOR …
1. With power switch off, turn
Talk
and
Listen
controls
completely counter clockwise.
2. Turn power switch on.
3.
Adjust the TALK volume control until the attendant is
clearly heard by the person outside the window when the
attendant is speaking 2" to 4" from the gooseneck
microphone at a normal speaking level. The green LED should
go on when the attendant starts talking and go off when the
attendant stops talking. If the green LED stays lit constantly, it
indicates either the TALK volume setting or the ambient noise is
too high.
4. Adjust the LISTEN control until the person outside
the window is clearly heard when speaking at a normal
level.
•
In most situations, both the TALK and LISTEN volume are
normally set to 11 to 12 o’clock position.

Operation Hints
1.
Increasing the talk volume control allows the attendant to speak
further from the gooseneck microphone as well as increasing the
talk channel volume. The optimum distance from the gooseneck
microphone should be maintained at approximately 3" or
conversations not directed to customers may be heard outside
the booth.
2.
Muting circuit: The unit will decrease the incoming volume
level by approximately 70% in about 30 seconds after the
attendant stops speaking into the gooseneck microphone. The
purpose of this feature is to decrease the amount of extraneous
noise entering the booth when no one is at the booth. Normal
volume level is restored when the attendant speaks into the
gooseneck microphone. The muting function can be defeated by
moved the shunt from MUTE ON to MUTE OFF as shown in
the diagram below.
