What a modern school intercom does
Today’s systems run over the same network as your Wi-Fi. Speakers, call buttons, clocks and displays plug into a switch, and the office controls everything from a console or a phone.
Intercom & paging
Two-way talk between the office and every classroom, plus all-call, zone and outdoor paging.
Bell schedules
Automated bells with custom tones, early-release and testing-day schedules, managed from one screen.
Emergency alerts
Pre-recorded lockdown, severe-weather and evacuation announcements, triggered from a phone, console or panic button.
Clocks & displays
Synchronized IP clocks and LED message boards that also flash visual alerts for ADA accessibility.
Classroom call buttons
A button on the wall reaches the office immediately, with the room number on screen.
Phone integration
Page from any desk phone or mobile, and tie alerts into your VoIP system and mass-notification apps.

Keep the speakers that work. Replace the headache.
Many campuses still run analog intercoms from the 90s with a head-end nobody can service. IP platforms from manufacturers like Valcom and Wahsega can reuse existing speaker wiring where it’s sound, add IP endpoints where it isn’t, and move control to the network your school already has.
- Hybrid designs that reuse good analog speakers
- IP speakers and call stations over PoE
- Works through power and internet outages
- Replaces separate bell, clock and PA systems
- Ties into VoIP phones and alert apps
- One vendor for hardware, software and support
Wired, mounted and tested room by room.
Global Dynamics Systems, Tech for Edu’s infrastructure partner, runs the cabling, mounts speakers, call stations and displays, and configures the head-end. Tech for Edu then supports the system alongside your network through the same 24/7 help desk.
