The Contacta STS-K002 Surface Mounted 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 teller window, pharmacy counter, ticket booth, government office, or information center, this system ensures staff and customers can hear each other clearly, eliminating the need to shout through the glass or repeat oneself. It's the ideal solution for smooth, professional interactions while maintaining safety and privacy on both sides of the counter.
The complete kit includes everything you need for instant clarity: separate customer-side surface-mounted speaker (STS-S60) and omnidirectional microphone (STS-M54) modules, a staff microphone and speaker unit with dual mute, a high-performance amplifier, and an under-counter hearing loop for customers using hearing aids. With its durable mild-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-K002 uses advanced technology to ensure high-quality sound and reliable operation. The cardioid staff microphone and omnidirectional customer microphone capture speech clearly, 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 low-profile surface-mount design keeps the customer counter unobstructed for a clean sightline. Reliable, efficient, and ADA-friendly, this is the professional standard for modern service counters.
FAQS:
Q: What is the difference between the STS-K002 and the Bridge Bar STS-K001?
A: Both kits provide the same two-way audio and hearing loop functionality. The STS-K002 uses separate customer-side speaker (STS-S60) and microphone (STS-M54) modules that sit directly on the counter for a lower profile and unobstructed sightline. The STS-K001 mounts both units on a single steel bridge bar that spans the customer counter.
Q: What types of locations use the STS-K002 system?
A: It's perfect for any environment where glass or barriers make normal conversation difficult, such as banks, post offices, theaters, information centers, public transit systems, ticket counters, embassies, and government buildings.
Q: Does this system include a hearing loop for customers with hearing aids?
A: Yes. The STS-K002 includes an under-counter hearing loop aerial (IL-AE99) that transmits sound directly to hearing aids equipped with a T-coil.
Q: How many components come in the kit?
A: The complete set includes the STS-A31H amplifier, STS-SU1-3W staff microphone and speaker unit (dual mute), STS-S60 customer surface-mounted speaker, STS-M54 customer surface-mounted microphone, IL-AE99 hearing loop aerial, and PS-55 power supply.
Q: Is installation complicated?
A: Not at all. The system is designed for quick installation with minimal wiring, and each component comes ready to connect right out of the box.
Q: What colors are available?
A: The STS-K002 is available in three finishes: two powder-coated options (Gray Leatherette / STS-K002-G and Black Textured / STS-K003-B) and a Stainless Steel option (STS-K003-SS).
