A school bell system is implied to integrate numerous timekeeping systems, particularly making sure that all of the bells call concurrently and also seem as one. The school bell system could use wireless (radio wave) signals to accomplish the synchronizing, particularly if accuracy is critical. The senders of these communication signals are clocks (or a master clock) and also the receivers are dispersed relays that may trigger tone generators along with bells.
The school bell system was normally designed for educational settings, and that is where they are largely utilized.
