TTU-1 Basic 2-Way Talk-Thru Electronic Communications SystemTTU-1 Basic 2-Way Talk-Thru Electronic Communications System
T he Basic Voice Communication System for
High-Security and Isolation Booth Situations
Today's security and isolation booths and ticket booths are often
the best step you can take to protect your employees. But do
they protect and also 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.
The Alpha Communications®/Norcon 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 Alpha Communications®/Norcon TTU system permits hands-
free, 2-way communication between the booth attendant and the
customer. Vox 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 circuity to
automatically attenuate the outside channel. If the gooseneck
microphone is not used for a period of 30 seconds, the outside
channel 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 inch round cutout in the barrier. Four
fasteners and two rubber gaskets needed for mounting
are supplied. Please specify barrier thickness when ordering.
The front face and housing are easily mounted on opposite
sides of the barrier using the fasteners supplied. The rubber
gaskets prevent slippage and protect the barrier surface. The
electronic section is then inserted into the housing and fastened in
place.
Note choice of continuous-duty, 117-Volt AC power
supply stepped down to 12 Volts (TTU-1A-X series), or
rechargeable nickel cadmium battery operation (TTU-1D-X series).
