TTU-7 Wireless Series
2-Way Wireless Talk-Thru Electronic Communication System
A wireless voice communications system for High-Security
and Isolation Booth Situations
Today’s security and isolation booths are often the best step

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 TTU-7 wirelessTalk-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. Avoids
shouting, repetition, and misunderstanding.
• 900 MHz digital intercom system provides highly
security CD quality sound.
• Simple installation with no wiring between desktop unit
and window unit.
• Special designed for the windows with sliding down
gates.
• Quality electronic design and engineering.
• .Rugged, tamper-resistant materials. Anodized aluminum
• Units available for ADA applications.
• Headset jack equipped for using the optional headset.

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-7 wireless Talk-Thru Communicator includes window unit
and desk-top unit, they both powered by high capacity rechargeable
batteries. The desktop unit communicates with the window unit
wirelessly.
Both units are working at full-duplex mode, but the speaker is muted
while the near –end is talking. The desktop unit is always priority for
talking; it interrupts the window unit and forces it to listen. The
paired unit works on the same ID. The working channel is
dynamically chosen according to the environment. If the present
working channel is jammed, both units will jump to another channel.
The system has 32 system IDs. 32 pairs of units can be installed
closely without interference.
In synchronous. The desktop unit automatically attenuates the
outside channel. If the desktop unit is not used for a period of 30
seconds, the listening volume will be reduced approximately 70%.
Normal operation is restored as soon as the attendant speaks into the
desktop’s gooseneck microphone. The automatic volume attenuation
circuit prevents outside noise from bothering the attendant.
The TTU-7W provides clear communication even in environments
with high ambient noise by shaping the sound for maximum
intelligibility. The maximum distance between could be around 10
feet.
HOW TO INSTALL …
1. Mount the TTU window unit using the method shown in
Figure (1).
2. The desktop is mounted on a marble base for stabilizing.

4. The outside unit needs a 3” to 4” diameter cutout in the barrier.
The rubber gaskets prevent slippage and protect the barrier surface.
Refer to Fig 2:

Remove the four (4) 6-32 assembly screws.
Remove the four (4) 8-32 mounting nuts from the mounting rods.
Separate the faceplate and housing. Hold the faceplate over the
partition opening. Take care to center the faceplate and align the
lettering horizontally. Masking tape can be used temporarily to
secure the faceplate to the outside of the partition.

HOW TO USE THE TALK-THRU COMMUNICATOR
1. There is a DIP switch on the Printed Circuit Board (Fig.3). SW 4 to
SW 8 is used for matching desktop unit and window unit. 32 system
ID can be set to match the desktop and window units. TTU-7W is
shipped with preset paired in the factory and ready to use. In case of
the user has multiple units installed in the same room and found
interference with each other, change the DIP switch setting to a
different combination. Both the desktop unit and the window unit
DIP switch must be set to the same position for matching purpose.

3. Use the battery charger to charge the desktop unit and the
window unit before used. The built-in battery charging
control circuitry will monitor the charging automatically.
4. Turn the TALK and LISTEN volume controls completely
counter clockwise.

5. Turn both window unit and desktop units on by switch power
on off switch to center position. In this position the unit also in
the auto mute mode. 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
