TTU-7X. The TTU for Security Gates and Shades.
The TTU-7X Series is a simple way to provide clear and high quality communication through glass or any barriers of any kind.
The TTU-7X is ideal for installations when it’s impractical to have the full 2½" control section of a TTU on the inside of the barrier. This normally occurs when a security gate or shade is used. The TTU-7X combines the external unit of the TTU-1 with a countertop inside unit from the TTU-3 giving customers the best of both worlds.
The TTU-7X combines a window-mounted customer facing unit with a countertop employee unit.
Installation
Installation is a simple, one-person operation. The unit is mounted into a 3-4 inch cutout in the barrier. All hardware and cables are supplied including a continuous-duty, 100-240 V power supply with 15 V output. Please specify barrier thickness when ordering.

ADA Compliant Option Components
A Note on Part Numbers
The TTU-7X has various options. Adding options to a unit modifies the part number. For example, the standard gooseneck microphone length is 18” but we offer a 10” and 24” option. A TTU-7X with a 10” microphone would be part number "TTU-1AX-10.” The options above can be combined to meet your needs. For example a bullet resistant TTU-7X with Wireless, Push To Talk, Noise Cancelling, ADA Compliance, and a 10” microphone would be “TTU-7BX-W-PTT-NC-ADA-10.” Note that the ADA Compliant Option includes a Monitoring and Recording Option so the two options can not be combined.
