T he Ideal Counter-T op C ommunication

System

Where It is Impractical to Cut a Hole In the

Ba rrier

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 communicat e ­clearly, c almly. In such
cases, the Alpha Communications®/Norcon TTU-3 is the
communication system of c hoice. The prismshaped units
of t he 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 T TU-1

Talk- Thru system. It is a duplex system, enabling the
att endant and the cust omer to talk and listen
simultaneously.

The TT U-3 provides c lear communication even in
environments with high ambient noise, shaping the sound
for maximum intelligibility. Its c ompression 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- bac k (as shown) or randomly. The unit with t he
gooseneck microphone and c ontrols goes inside the
booth; t he unit without c ontrols is mounted outside the
booth. There are t wo ways t o install the TT U-3:
either run the c able between t he units t hrough 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 st epped down t o 12 Volts.
