School Wireless Intercom System

THE CHALLENGE

Salisbury School is an independent, all-boys boarding school in Salisbury, CT, spread across a 725-acre campus with multiple academic and residential buildings. The school board was searching for a school wireless intercom system that could deliver reliable overhead paging, severe weather alerts, and two-way intercom communication throughout the entire campus. Their ideal wireless intercom and PA solution had to be fully campus-wide, cost-effective, and require no cabling or trenching between buildings. It also needed to be easy to self-install, offer modular expandability to support future campus growth, and demand minimal ongoing maintenance. The school’s required feature set included all of the following capabilities:

  • Two-way voice communication between all buildings and classrooms and the main office, enabling instant, campus-wide intercom connectivity.
  • Automated, pre-recorded, and live PA announcements that can be broadcast to a specific building, a designated zone, or the entire campus.
  • NOAA weather radio integration for fully automated severe weather alerts delivered instantly across all wireless PA speakers.
  • Compatibility with the school’s legacy wired PA panel, allowing simultaneous activation of both the wired and the new wireless PA systems during emergencies or routine communications.
  • A fully expandable and modular design, allowing wireless speakers, call stations, and intercom units to be easily added, moved, or reconfigured as the campus grows.

THE SOLUTION

School Wireless Intercom System

Visiplex proposed a school wireless intercom system specifically designed to meet Salisbury School’s campus-wide communication requirements. The solution featured a wireless paging base station located in the main office, fully integrated with a NOAA weather radio interface for automated severe weather alerts. The system also included wireless two-way intercom stations for real-time communication with every classroom, wireless ceiling PA speakers for classrooms, and wireless wall-mount PA speakers for hallways and common areas. For outdoor coverage, wireless PA horn speakers were installed to deliver clear announcements across the schoolyard and all exterior spaces.

To ensure seamless operation with existing infrastructure, a dedicated wireless PA controller was added to interface with the school’s legacy wired PA system, allowing both wired and wireless speakers to receive simultaneous announcements.

This fully wireless school intercom system eliminated the need for trenching or cross-campus cabling and required only standard AC power for the intercom stations and outdoor PA horns. The result was a cost-effective, scalable communication solution that supports reliable daily announcements, emergency notifications, and future campus expansion. The modular, fully wireless design of the school wireless intercom system allowed Salisbury School’s maintenance staff to complete a fast, cost-effective installation with minimal disruption to daily operations.

THE RESULTS

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

  • Each classroom can now initiate two-way voice communication directly with the main office for immediate assistance or coordination.
  • The main office can place an intercom call to any specific classroom to enable instant, two-way communication when needed.
  • Live public address announcements can be broadcast campus-wide for daily messaging or urgent notifications.
  • Automated, pre-recorded weather alerts are delivered in real time through integrated NOAA weather radio activation.
  • The system is fully expandable, allowing wireless speakers and intercom stations to be added, moved, or reconfigured as the campus grows.
