T he Ideal Counter-T op Communication System
Where It is Impractical to Cut a Hole In the Barrier
There are times when its impractical -
for various reasons - to cut a 3- to
4-inch hole through an isolation
barrier. But your employees and your
customers still have a way to
communicate - clearly, calmly. In
such cases, the Alpha
Communications®/Norcon TTU-3 is
the communication system of choice.
The prismshaped units of the TTU-3
are ideal for mounting on a countertop on both sides of a barrier.
Yet they allow free communication through barriers typically found
in banks, cashier's booths, information booths, and similar
environments.
How It Works...
The TTU-3 incorporates the same high-quality electronics as
the basic (Norcon) patented model TTU-1 Talk-Thru system. It is
a duplex system, enabling the attendant and the customer to
talk and listen simultaneously.
The TTU-3 provides clear communication even in
environments with high ambient noise, shaping the sound for
maximum intelligibility. Its compression circuitry decreases loud,
annoying sounds.
How To Install...
The TTU-3 comes ready to operate. The prism units are
quickly and easily mounted on the counter-top on opposite sides
of the barrier. They can be positioned back-to-back (as shown)
or randomly. The unit with the gooseneck microphone and
controls goes inside the booth; the unit without controls is
mounted outside the booth. There are two ways to install the
TTU-3: either run the cable between the units through a small hole
in the barrier, or under the counter-top (as shown on next page).
The TTU-3 uses a continuous-duty, 117-Volt AC power
supply which is stepped down to 12 Volts.
