A CASE STUDY

Wireless Public Address System for Covanta Hillsborough, Inc.

Commercial Public Address System

THE CHALLENGE

Covanta Hillsborough, Inc., a resource recovery facility near Tampa, Florida, needed a reliable and scalable commercial public address system to replace their outdated wired PA setup. As a facility that converts solid waste into clean, renewable energy, timely communication was critical for both daily operations and emergency situations. Ken Defreitas, Lead Technician at Covanta, sought a wireless public address solution that would:

  • Deliver high-volume outdoor audio coverage
  • Include weatherproof outdoor speakers for harsh environments
  • Offer remote access to the central paging system via phone for field supervisors
  • Be expandable for future growth
  • Be simple enough for in-house electricians to install and maintain

THE SOLUTION

Commercial Public Address System

Visiplex provided a fully wireless commercial public address system tailored to Covanta’s unique facility layout and communication needs. The solution included a wireless paging base station installed in the control room, high-power transmitter for complete RF coverage across the facility, multiple VNS2200 wireless outdoor speaker controllers housed in NEMA weatherproof enclosures, each controller powering VNS2088 high-power horn speakers for loud, reliable voice broadcasts

To meet the requirement for remote paging access, the base station was upgraded with the telephone interface module, allowing supervisors to dial in and broadcast messages from any phone.

Because the system is wireless, it eliminated the need for extensive cabling, reducing installation costs and allowing quick setup using only standard AC outlets at each speaker location.

THE RESULTS

The newly installed commercial public address system delivered the following benefits:

  • Instant, clear voice alerts from the control room to all facility zones for both emergency and routine announcements
  • A network of high-powered outdoor PA speakers providing full facility-wide audio coverage
  • Simplified installation and maintenance, handled entirely by Covanta’s on-site electricians
  • A fully scalable system that allows for easy addition or relocation of speakers as the facility grows
  • Modular, expandable system design allowing quick addition or relocation of components without new wiring

This wireless commercial public address solution not only improved safety and communication but also delivered cost-effective scalability for Covanta’s future operational needs.
