Customer Service Window Intercom – Professional 2-Way Full Duplex Hands-Free Communication System
The ZDL-380E Customer Service Window Intercom is built for seamless communication in environments where staff and customers are separated by glass, acrylic, or security barriers. Perfect for banks, pharmacies, ticket booths, government offices, and customer service counters, this system ensures crystal-clear communication with true full-duplex, hands-free operation, allowing both sides to speak and listen at the same time—no push-to-talk buttons required.
The master operator station features a compact aluminum alloy and durable rigid plastic housing, a 3-watt built-in speaker, and a high-gain low-noise microphone for professional-grade audio clarity. Its 18-inch flexible gooseneck microphone provides superior positioning and voice pickup for the operator.
True Full-Duplex Hands-Free Communication – Natural, uninterrupted conversations without push-to-talk
On the customer side, the 2.5-inch compact speaker with built-in microphone delivers clear audio while maintaining a minimal footprint on the counter. Both master and customer stations feature independent volume controls, allowing operators to fine-tune microphone and speaker levels for optimal clarity in quiet or noisy environments.
Installation is effortless—no drilling or permanent setup required. The customer sub-station connects to the master station with the included 6-foot audio cable, and the master station supplies both power and audio, eliminating the need for extra wiring or power sources.
For recording or compliance, the master station includes an auxiliary audio output for easy connection to an external recorder. Built with rugged materials to withstand heavy daily use, this plug-and-play solution is designed for fast deployment and reliable performance.
