What is a school bell system?
A school bell system is a scheduled signaling installation that rings class-change, dismissal and event bells automatically throughout the day. Modern wireless systems trigger existing bells or play tones over PA speakers from a GPS-locked schedule, so every bell rings on time, every time, with no manual clock-watching.

Bells that ring late rob teaching time; bells that ring wrong cause chaos. Innovation Wireless bell systems run up to 99 schedules and 9,999 events from the same GPS-locked time base as your clocks, class changes, dismissals, assemblies and shift signals, all automatic.
How It Works
Your schedule. Our signal. Their bells, or ours.
A compact tone generator holds your bell schedule and receives accurate GPS time wirelessly from the KRONOsync® transmitter. It can drive your existing physical bells and buzzers, or play tones and recorded messages over a wireless, Wi-Fi or PoE speaker system. Networked sites can manage everything through IP-PoE tone generators from one screen.

Bells are also an emergency endpoint: in our school lockdown system, the same scheduling network can sound alert patterns from a panic button press, alongside PA audio and LED instructions.
