What is a synchronized clock system?
A synchronized clock system is a network of clocks that all receive their time from one central source, so every clock in every building shows exactly the same accurate time. In a wireless system, a licensed-UHF transmitter broadcasts a GPS-locked time signal that analog and digital clocks receive automatically, with no wiring between clocks.
When the bell rings, every clock should agree. Innovation Wireless synchronized clock systems keep an entire campus on one GPS-locked time base, classrooms, hallways, gyms and offices all matching to the second, with nothing to reset after power outages or daylight-saving changes.
How It Works
One transmitter. Every clock on campus.
The KRONOsync® transmitter broadcasts on a licensed 467 MHz UHF frequency chosen for its ability to penetrate commercial construction, concrete, steel and brick. One transmitter covers approximately 300,000 square feet; repeaters or an outdoor antenna extend coverage to multi-building campuses. Clocks listen for the signal and correct themselves continuously.

Why Facilities Switch
The end of clock patrol
- No more manual resets after outages, daylight-saving or schedule changes
- Bells and clocks agree, class changes happen on time, everywhere
- Add clocks anytime: a new clock finds the signal and sets itself
- Mix analog, LED digital and existing wired clocks on one time base
Synchronized time also powers the rest of the platform: the same signal drives our wireless bell scheduling, and the clocks work alongside PA speakers and LED message boards in our school lockdown system.
