Norcon Communications Top Categories
- Norcon Communications Talk-Thru Units (Window-Mounted) - The TTU-1 is the original. It's a small electronic communicator that fits into a 3-to-4-inch hole drilled through a glass partition, with the operator side and customer side talking through built-in speakers and microphones. The TTU-1AX runs on AC power and is the most common configuration; the TTU-1DX-L is the same product with battery power for sites where running an outlet to the booth isn't realistic. Both can be ordered with bullet resistance, wireless operation, push-to-talk, noise cancelling, monitoring and recording, or ADA compliance.
- Norcon Communications Countertop Talk-Thru Units - If the glass can't be drilled, the TTU-3 sits on the counter instead. Two prism-shaped units, one on each side of the barrier, deliver hands-free audio between staff and customer. The TTU-3X is AC powered, the TTU-3DX-L is battery powered, and the same customization menu applies.
- Norcon Communications High-Security and Specialty TTUs - The TTU-4 and TTU-5 are built for environments where tampering is the bigger concern than ambient noise. Everything, including the microphones, sits inside a sealed enclosure. Correctional facilities use these for inmate-to-visitor windows; secure patient areas use them for the same reason.
- The TTU-7X is the in-between unit. It's used when there's a security gate or roll-down shade behind the glass that doesn't leave room for the standard 2-1/2-inch interior section of a TTU-1.
- Norcon Communications Accessories - Gooseneck microphones (the C99-X is the common one), headsets, and foot switches are sold as add-ons to customize the operator-side setup. Norcon also builds custom TTUs for government agencies, including units with telephone-handset support and translator capability.
Who Uses Norcon Communications Products?
Three buyer profiles cover most of who orders Norcon TTUs through DK Hardware:
The first group is people running ticket booths, box offices, and transit windows. This is the original use case from 1972 and still the biggest. Stadiums, theaters, ski resorts, train stations, and toll plazas all need to handle high-volume, high-noise transactions through glass.
The second group is anyone running a teller-style counter behind protective glazing. Banks, pharmacies, government service desks, and check-cashing counters fit here. The bullet-resistant TTU-1AX is the standard spec for most of these.
The third group is correctional and high-security work. Inmate visitation rooms, secure patient interview areas, and similar settings use the TTU-4 and TTU-5 specifically because there's nothing on the outside of the unit to grab, adjust, or break.
There's also a smaller fourth group - quarantine, isolation, and screening installations - which grew significantly during COVID and hasn't fully tapered off.
