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 
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    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.

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. 
   On the inside of the partition mount the housing over the four (4)  

8-32  mounting rods. Be certain to position the housing so that the 

   battery charger jack faced down and the antenna is straight up.

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 

6.  window is clearly heard when you speaking at normal level. 

Make sure when speaking to the gooseneck microphone, the 
green LED above the TALK volume comes on and when stop 
talking the green LED comes off. Otherwise lower the TALK 
volume.
