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 proposed Visiplex commercial wireless intercom system featured multiple two-way wireless intercom stations strategically installed throughout the facility to provide clear, direct communication between key areas. To improve voice coverage in public and high-traffic zones, the system also incorporated indoor wireless PA speakers for live announcements and scheduled alerts.

To enhance visibility and support ADA compliance, the solution was expanded to include wireless LED message boards and multi-color beacon lights—ensuring high-visibility visual alerts across the entire facility.

With its modular, wireless architecture, the system was designed for installation by the facility’s in-house maintenance team, eliminating the need for complex wiring and significantly reducing implementation costs. Final system testing, commissioning, and on-site staff training were provided by Visiplex technicians to ensure seamless integration and reliable 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
