Installation & Operating

Instructions

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. Black wire and shield wire have to be grounded.

The outside unit needs a 3” to 4” cutout in the barrier. The

rubber gaskets prevent slippage and protects the barrier surface;

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)

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.

5.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.

6. For power connection, route one pair cable (with the

connector on one end) From the inside unit to the location of

the PS-8a Power supply. Connect the conductors to the power

supply (RED to +, BLACK to -). Plug the connector to its mate

from the printed circuit board.

7. The sound absorbing material in the housing may be

removed during installation but should be replaced for normal

operation.

8. For best result maintain maximum separation between

inside and outside units.

TTU-7X Series2-WayTalk-

ThruElectronic 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 is it equipped to protect

and maintain your very important public image? Not if clerks and

customers have to yell and repeat themselves to be heard or

understood.

Norcon’s Patented TTU-7X 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.

•Quality electronic design and engineering.

•Now with removable XLR mic for your convenience.

•Avoids shouting, repetition, and misunderstanding.

•Special made for the window with slide down gate.

•Rugged, tamper-resistant materials. Anodized aluminum

•Units available for ADA applications.

•Headset jack equipped on all models for using the optional

headset.

•Export models available.

HOW TO USE THE TALK-THRU COMMUNICATOR:

With power switch off, turn Talk and Listen controls completely

counter clockwise. Turn the unit ON by switching AUTO MUTE switch

to the up 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.

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.

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. Install a headset into the headset jack will allow communications from

the headset and disconnect the gooseneck microphone.

3. The unit will decrease the incoming volume level by approximately

70% in about 30 seconds after the attendant 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 NO MUTE (down) position

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-7X Talk-Thru Communicator now incorporates advanced

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 a

ttendant speaks into the

gooseneck microphone. The automatic volume attenuation circuit

prevents outside noise from bothering the attendant. The TTU-7X

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.

3. Use holes on the housing where required for installation.
