4.Recommended cables for wiring
For all Spk /mic connections use West Penn Wire #357.This is a
four conductor 22 gauge wire with two wires that are shielded
and two are without shield. Use the shielded pair for the mic
connection. For power and paging connections use West Penn
wire #221. This is a stranded single pair 22 awg, Plenecon -II
jacket Rohs cable. Keep Mic/Spk and power cable bundles away
from other power cable. 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, maintain maximum separation between inside
and outside units.

HOW TO USE THE TALK-THRU COMMUN/CA TOR:
1. With power switch off, turn Talk and Listen controls completely counter
clockwise.
2. Turn the unit on the unit by switching POWER switch to the up 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 goose neck microphone at a normal speaking level. The
green LED should turn on when attendant starts talking and go off
when the attendant stops talking. If the green LED stays lit
constantly, ii 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.

TTU®-3X Series 2-Way Talk-Thru Electronic
Communication System:
A voice communications system for High-Security and Isolation
Booth Situations.
In today's security conscious environment, isolation booths are often
the ideal recourse to protect your employees. But does it facilitate
and help maintain your very important public image? Not if clerks
and customers have to raise their voice and repeat themselves to be
heard or understood.
Norean's Patented TTU®-3X 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.
FEATURES
•
Clear 2-way hands-free voice communication.
•
Superior quality electronic design and engineering .
•
Avoids raising your voice, repetition, and misunderstanding.
•
Simple, one-person installation. No need to cut a hole in the
barrier.
• Rugged, tamper-resistant materials. Anodized aluminum
• Removable XLR mic for your convenience .
•
Units available for ADA applications .
•
Headset jack equipped on all models. Headset can be ordered
separately.
• Export models available.
Operation Hints:
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 goose neck microphone should be maintained at approximately
3" or conversations not directed to customers may be heard
outside the booth.
The unit will decrease the incoming volume level by approximately
70% in about 30 seconds after the attendant stops speaking into
the goose neck 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 POWER switch to NO
MUTE position
Install a headset into the headset jack will allow communications
from the headset and disconnect the gooseneck microphone.

HOW IT WORKS ...
The Norean 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®-3X 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
X 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 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.
