The ADC SMART BELL is the latest solution for schools and factories that require an automatic time alert system for signaling class changes, shift rotations, breaks and any other timed signal application. With the ADC SMART BELL, you can access, control and schedule bells individually via any authorized smart phone, and no designated computer is required. For those who wish to program the bell times themselves it is a very simple process. Connect any pre-authorized smart phone to the schools/factories Wi-Fi network or switch mobile data on, enter the password and bell schedules on the free phone app, then press save, The phone’s Wi-Fi and mobile data can now be switched off. The phone is no longer required. An even easier way is to email a list of times the bell must ring to bells@schoolsystems.co.za. We will then program the unit over the air from our office. As with most bell systems you also have the ability to ring the bells manually.
