SNS Bell Scheduling

When bells are not synchronized with the clocks on the wall, confusion occurs and educational hours can be lost. Managing multiple school bell schedules doesn't have to be a cumbersome and complex process. SNS Bell Scheduling System allows you to easily control the bells in every corner of each one of your schools from any computer with access to your secure SNS Application Management Platform software.

Simply connect your bell or tone equipment to an SNS Network Bell Relay plugged into an Ethernet access point. Use the highly intuitive software interface to set up bell schedules for regular school days for each school in your district, special schedules for early dismissal or late start days, or even impromptu bells for fire or weather drills.

You can even schedule your bells for every day of the entire school year, using the built-in calendar functionality in the software. For last-minute bell changes and drills, simply access the secure software from any computer on your network to adjust the timing and communicate the new schedule to your bells.
