Contacta STS-K001 Bridge Bar Window Intercom System

The Contacta STS-K001 Bridge Bar Window Intercom System is designed for clear, effortless communication in areas where glass or security screens obstruct the view. Whether you're at a bank, ticket counter, government office, or information booth, this system ensures that staff and customers can hear each other clearly, eliminating the need for shouting through the glass or repeating oneself. It's the ideal solution for creating a smooth, professional interaction while maintaining safety and privacy on both sides of the counter.

The complete kit includes everything you need for instant clarity: the Bridge Bar speaker and microphone unit for customers, a staff headset microphone and speaker, and high-performance amplifier, and an under-counter hearing loop for customers using hearing aids. With its durable steel construction and sleek powder-coated finish, it's designed for heavy daily use in busy public environments. And because it's pre-engineered for plug-and-play setup, you can have it up and running quickly without complicated configuration. 

Behind the scenes, the STS-K001 is equipped with advanced technology that ensures high-quality sound and reliable operation. Directional microphones minimize background noise, while the precision-tuned amplifier delivers crystal-clear audio on both sides of the barrier. The integrated hearing loop makes it fully accessible, and the anti-pry, low-profile design blends seamlessly into your workspace. Reliable, efficient, and ADA-friendly, this is the professional standard for modern service counters.
