Product Specification Sheet APS189 - Rev. 03/2017 TTU-1 Basic 2-Way Talk-Thru Electronic Communications System T he Basic Voice Communication System for Mechanical Specifications High-Security and Isolation Booth Situations Outside Face Plate: Solid aluminum, anodized finish, tamperresistant Control Housing (Inside): Machined aluminum, anodized finish, tamper-resistant The Alpha Communications®/Norcon patented TTU-1 TalkThru 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. Dimensions: Outside face plate - 5.00" dia x 0.50"D Inside control housing - 5.00" diameter x 3.50"D Microphone and gooseneck 18 in. Weight: 4.50 lbs. (model# TTU-1A-X) How It Works... Mounting: The Alpha Communications®/Norcon TTU system permits handsfree, 2-way communication between the booth attendant and the customer. Vox circuitry facilitates ongoing, clear, 2way conversation at all times - as if the two parties were together in the same room. Partition hole 3 to 4 in. dia. (3.50" recommended) Please specify barrier thickness when ordering Panel Controls: Listen volume, talk, volume, on-off switch, charger socket (on battery unit) 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 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. Electrical Specifications (Booth Unit) Audio Frequency Response: Selectively shaped for maximum voice intelligibility Audio Power: 2 watts per amplifier Distortion: Less than 2% 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. Listen Mode: 20 dB compression Talk Mode: Vox How To Install... Microphones: Electret (inside gooseneck mic. is 18.0" long). Optional 8.0" or 24.0" models avail., at extra cost. Please specify when ordering! Power Supply: Input: 120 VAC, 60 Hz, Output: 15 VDC, 175mA Useful time (on battery unit): 10 to 12 hours per charge Charge time (battery unit): 5 hours for full charge. Unit can be used while charging 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). Features 8 Available Models 1.
