COMMERCIAL WIRELESS INTERCOM SYSTEM

A CASE STUDY

A Two-Way Paging System for Nestle Quality Assurance Center

Commercial Wireless Intercom System

THE CHALLENGE

The Nestlé Quality Assurance Center (NQAC) required a robust warehouse paging system to deliver two-way intercom communications, voice paging, and emergency mass notifications throughout its 84,000-square-foot facility. The goal was to deploy a fully integrated commercial wireless intercom system that would enable two-way communication between the control center and specific laboratory areas, while also supporting daily public announcements and instant emergency notifications. To meet these requirements, the system needed to provide the following core capabilities:

  • Two-Way Intercom communication across multiple areas

  • Reliable live and pre-recorded, voice paging to all zones

  • Instant emergency alert broadcasts for staff safety
  • Integration with LED message boards and visual alert devices for enhanced visibility

  • Wireless indoor PA speakers and intercom stations for full coverage

  • Scalable, modular architecture for future expansion without re-wiring

THE SOLUTION

Commercial Wireless Intercom System

The Visiplex commercial wireless intercom system was successfully deployed using multiple two-way wireless intercom stations strategically placed throughout the facility to ensure clear and direct communication between key areas. To enhance voice coverage in common and public zones, the system also included indoor wireless PA speakers for live announcements and scheduled alerts.

For added visibility and to support ADA compliance, the solution was expanded with wireless LED message boards and multi-color beacon lights, delivering high-visibility visual alerts across the entire facility.

Thanks to its modular, wireless design, the system was fully installed by the facility’s in-house maintenance team—eliminating the need for complex wiring and significantly reducing installation costs. Final testing, commissioning, and on-site training were completed by Visiplex technicians to ensure smooth integration and dependable day-to-day operation.

THE RESULTS

Optimized Commercial Wireless Intercom System Performance – The wireless intercom system was successfully implemented across all facility’s zones, significantly improving site-wide safety, operational efficiency, and communication. The solution enhanced daily workflows and emergency readiness while delivering the following key capabilities:

  • Two-way communication with multiple areas in the facility

  • Enhanced visual alerts using LED message boards and beacon lights, ensuring ADA and hearing-impaired compliance

  • Live and pre-recorded voice messaging for diverse workforce communication

  • Modular, expandable system design allowing quick addition or relocation of components without new wiring

The fully wireless design allowed Tesla to deploy the warehouse paging system with minimal disruption, using internal resources for installation and reducing overall implementation costs.
