  • More than just a class change system!

In a time where effective communication and security within schools are more important than ever, Bodet Time offers the perfect Class Change, PA and Synchronised Timekeeping solutions.

Our class change system is designed to be as versatile as needed for your class change schedule and communications. The accurate timekeeping will keep your staff and students on time for class changeovers and keep them informed of any urgent events, such as evacuations or class lockdown.

The class change and PA system is the perfect tool for timing day-to-day school activities such as class start and end times, plus the public address feature can also be used for voice notifications and for playing music.

Wide range of tones to choose from

Long gone are the days of traditional single-tone school bell rings to signify audible indications for class times and lunch rotations. The Bodet Time Class Change, Lockdown Alert and PA Systems are used in thousands of schools across the UK and Europe and allows you to broadcast customisable alerts in line with your class change and communications policies.

You have an extensive choice of tones and melodies to meet your needs. The system also has a programmable electronic timer, which allows you to create a notification schedule for the entire school week without requiring manual operation. Using the zoning functionality you can tailor schedules for different parts of the school grounds.

Using the Bodet Time Synchronised Class Change & PA System, you can save time and effectively communicate class start and finish times automatically using customisable tones. It is easily installed, and we have successfully equipped both new build and established schools and educational establishments catering for all students’ ages and needs.

What are the benefits of Bodet Time's Class Change System?

There are many benefits to be gained from installing a class change system. We offer a fully customisable way of notifying your staff and students of school timings which can be tailored to be fun, exciting, or subtle, depending on the age of your students.


Bodet Time's solutions provide the following benefits:

  • Ability to link synchronised clocks
  • Class change alerts are automatic and synchronised
  • Class change alerts can be cancelled automatically during school holidays
  • Different zones can be created, each having specific alert times, melodies or recorded announcements
  • Ability to schedule when bells will sound during exam periods.
  • Messages can be announced via microphone either over the whole site or to specific zones, or use our Harmonys Talk smartphone app.
  • Music and other audio can be streamed to any sounder on your network

Bodet Time's Synchronised Class Change & PA Systems can be tailored to the layout of your premises.

This means you can broadcast music or announcements to only those areas that need them without disturbing other classrooms.

Our PA feature means you can address the whole school or campus with urgent notifications or target specific areas, such as the school office or staff room, for paging individual staff members.

  • Able to synchronise with clocks
  • Choice of preloaded or customisable recordings
  • Create schedules for specific areas of your premises

Bodet Time's Class Bell Systems will elevate your school’s scheduling to be more efficient, while allowing you to customise the bell tones to suit your needs. Our system makes it easy for you to notify the start of a class, lunch and break times and end-of-day notifications.

Harmonys gives you the flexibility to zone your alerts to different school areas without disrupting other classes or confusing students. For example, if you want to notify Key Stage 1 or 2 children of their lunch break, you can assign different bell tones to different key stages.

School safeguarding has also become a prominent concern in recent years. With Bodet Time's Class Change Systems, you can safeguard your staff and students by providing instant voice messages and emergency alerts throughout your network of speakers at the touch of a button or via a smartphone app.
