COMMERCIAL WIRELESS INTERCOM SYSTEM
A CASE STUDY
A Two-Way Paging System for Nestle Quality Assurance Center

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:
THE SOLUTION
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:
