Norcon TTU-7X - Talk Thru Communicator Manual

Introduction

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.

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 attendant 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.
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 theconnector 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 beremoved during installation but should be replaced for normal operation.
8. For best result maintain maximum separation betweeninside and outside units.

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 fromthe 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

Introducing the Norcon TTU® -1X NC:
When using a Talk-thru unit in a noisy area such as heavy traffic street, a crowed movie theater hall way or a gas station, the noise makes the conversation difficult. A powerful DSP chip inside the Norcon noise cancelation unit samples an ambient noise environment and attenuate the noise around the desired speech signals. As a result, continuous and repetitive noise is removed; a clear conversation can be had, even with a passing truck in the background. To take the advantage of this new technology, the existing unit can be sent to us for upgrade.

Introducing the Norcon TTU-1X Series:
There are times, when the isolation barrier has a 3" to 4" hole on it, the Norcon TTU-1X is special design for it.
