What Today’s School Intercom Should Deliver

 

A reliable intercom system is at the heart of every school’s daily operations and safety plan. From morning announcements and class-change bells to emergency alerts, these systems keep staff and students connected when it matters most.


At School Intercom and Sound Services, we help schools go beyond the basics. While traditional intercoms provide classroom communication, all-call paging, bell scheduling, and emergency notifications, we specialize in upgrading and modernizing these systems to meet today’s safety and technology standards.

Our services include:


  • System Upgrades & Repairs – Extend the life of existing intercoms or replace outdated units with modern, reliable solutions.
     
  • Campus Safety Integrations – Add lockdown alerts, panic buttons, and emergency call stations for faster response in critical moments.
     
  • Bell-Tone Software Solutions – Program or replace scheduling software to streamline announcements and daily operations.
     
  • Network & VoIP Integration – Expand communication across the entire campus with modern wiring, speakers, and VoIP compatibility.
     
  • Trusted Brand Support – Expertise with leading systems including Bogen, Rauland, Dukane, Telecor, Valcom, and more.
     

Whether you need quick troubleshooting, preventive maintenance, or a complete system upgrade, our team is dedicated to keeping your school’s communications dependable, safe, and future-ready.
