Two-way Communication system with security surveillance
A color video camera with pin-hole lens built-in to a
bidirectional communication device used for surveillance.
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® -1 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. It is the most widely used system of its type in
the U.S., and the world.
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®-1 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®-1 provides clear communication even in
environments with high ambient noise by shaping
the sound for maximum intelligibility. Its
compression circuitry decreases loud, annoying sounds.
Installation of the TTU® -1 is a very simple, one-person
operation. All that’s needed is a 3” to 4” cutout in the barrier. Four
fasteners and two rubber gaskets for mounting are supplied.
The front face and housing are easily mounted on opposite sides
of the barrier using the fasteners. The rubber gaskets prevent
slippage and protect the barrier surface. The electronic section is
then inserted into the housing and fastened in place.
Installation Instructions
Remove the four (4) 6-32 assembly screws.
Separate the housing and electronics assembly. Unplug
electronic assembly from the faceplate and housing.
Set the electronic assembly aside, carefully.
Remove the four (4) 8-32 mounting nuts from the
mounting rods.
Separate the faceplate and housing.
Discard the shipping spacers located between the faceplate
and housing if there are any.
Hold the faceplate over the partition opening. Carefully
center the faceplate and align the lettering horizontally.
Masking tape can be used to temporarily hold 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 threaded hole is
positioned properly. If using tubing, orient the hole in
the direction which the tubing is to exit (left, right,
top, and bottom). If tubing is not being used, place the
plugged hole at the bottom.

For power connection, route 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.

TTU-1 P.1.
1. With power switch off, turn Talk and Listen controls
completely counter clockwise.
2. Turn on the unit by switching the AUTO MUTE to it’s center
position. In this position, the unit is 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
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.
1. Increasing the talk volume control allows the attendant to speak
further from the microphone as well as increasing the talk
channel volume. The optimum distance from the microphone
should be maintained at approximately 3” or conversations not
directed to customers may be heard outside the booth. Watch
the green LED above the TALK volume control, it should be
on ONLY when talking into the gooseneck microphone.
2. Installing a headset into the Headset jack will allow
communications from the headset and disconnect the speaker
and the gooseneck microphone.
3. The unit will decrease the incoming volume level by
approximately 70% some 30 seconds after the attendant stops
speaking into the microphone. The purpose of this feature is to
decrease the amount of extraneous noise entering the booth.
Normal volume level is restored when the attendant speaks into
the microphone. The muting function can be defeated by
switching the AUTO MUTE switch to the OFF position.
