Norcon Communications TTU-1 Series Manual

INTRODUCTION

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.

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®-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.

HOW TO INSTALL

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


Be certain to position the housing so that the threaded hole can be positioned properly. If using tubing, orient the hole in the direction which tubing is to exit – LEFT; RIGHT; TOP or BOTTOM

HOW TO USE THE TALK-THRU COMMUNICATOR

OPERATION HINTS

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.

TTU® -7

Special design for the window with a secure pull-down gate or shade.
In some cases, when it's impractical to mount the inside control section of the TTU® -1 in a window with secure gate or shade the TTU-7® is your choice.
The TTU®-7 incorporates the same high-quality electronics as the basic TTU®-1, but with a 1" or 1- 3/8" (TTU®-7B) low profile window mount section, and a prism shaped counter mounting control section.

Introducing The Norcon TTU® -3 Series

There are times, when it is inconvenient to cut a 3" to 4" hole through an isolation barrier; the Norcon TTU®-3 is the solution for this situation.
The TTU®-3 is a pair of 6" or 12" prism-shaped units for mounting on a counter top on both sides of a barrier. They allow hands free communication through barriers typically found in banks, cashier's booths, information booths, and similar environments.

TROUBLESHOOTING

You may occasionally encounter a problem with your TTU® system. If this happens, refer to the following list. If additional help is needed, please contact us.

3. Conversation cutting-off and breaking-up

• Is the TALK volume setting too high?
  Turn down TALK volume to a proper level.
• Is the attendant talking too far from the gooseneck microphone?
  The idea distance is 3" to 4" from the gooseneck microphone.

4. TTU ® -1 D does not work when operated by internal battery

• Are the batteries fully charged?
  If the unit is newly installed, allow the batteries to be charged for 10-12 Hrs before operating. The unit can be used while the batteries are being charged.
• Is the battery charger plugged into a working outlet?
