The Norcon TTU-1 is the most popular 2-way transaction intercom in the world for hands-free communication between your employees and your customers. Fulfilling specific communications needs of airports, hotels and hospitals other venues where an amplified window intercom is needed for 2 way communication.

How the TTU-1 talk thru window intercom works

The Norcon TTU-1 Talk Thru 2-Way Communicator window intercom provides hands-free communication between people separated by security or isolation barriers. It is the most widely used barrier intercom system of its type in the world.

The Norcon TTU-1 provides crystal clear communication even in environments with high ambient noise through the use of compression circuitry which helps to reduce loud, annoying sounds.
Solid aluminum, anodized finish, tamper-resistant construction. Unwanted background noise is minimized through the use of automatic volume attenuation circuitry.

If the gooseneck microphone is not used for 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. 

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. 


Clear, 2-way hands-free voice communication 
Rugged, tamper-resistant materials 
Simple, one-person installation 
Headset jack permits telephone style headset or wireless microphone 
Optional removable gooseneck microphone INCLUDED !!!


Installation of the Norcon TTU-1 is a simple, one-person operation. All that's needed is a 3-4 inch cutout in the barrier. Four fasteners and two rubber gaskets for mounting are supplied with the unit.

The fasteners are used to mount the front face and housing on opposite sides of the barrier. The electronic section is then inserted into the housing and fastened in place. The rubber gaskets prevent slippage and protect the barrier surface. Please specify barrier thickness when ordering.

All Norcon Talk Thru window intercom systems are shipped complete with mounting hardware, instructions, and power supply.

NOTE:  Each microphone includes a transformer and an aluminum channel to run your power cord through when the microphone is installed through glass / plexiglass as seen in the photo.  Microphones are ready for operation as soon as the power cord is connected to the transformer.  It is as simple as connecting 2 wires to the screws in the back of the transformer, plugging the transformer to your wall outlet and you are ready to roll. 

ALL of the microphone units that we have are the Norcon TTU-1 but the actual mouth piece may vary.
