4. Route 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, route 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 the unit on the unit by switching AUTO MUTE switch to
the center position. In this position the unit also in the auto
mute mode.
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 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.

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.

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. 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 switching the
AUTO MUTE switch to AUTO MUTE OFF position.
3. Install a headset into the headset jack will allow
communications from the headset and disconnect the
gooseneck microphone.

HOW IT WORKS ...
The Norcon TTU system permits hands-free,
®
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 ...
Mount the TTU unit using the method shown in figure (1).
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 control, power switch,
power indicator LED and speaker.
The "Outside" unit has no electronics. A speaker and a
microphone are attached to the "Outside" unit.
3. Use holes on the housing where required for installation
