Broadcast coronavirus safety reminders in your school

As pupils and staff return to school during the coronavirus outbreak, there are new safety measures they will need to adhere to. Since this is a return to a familiar environment with familiar faces, it’s possible that these steps could be forgotten without frequent reminders.

With Bodet’s Lockdown Alert and Class Change Systems, you have the opportunity to communicate critical information throughout the school day, using either live or pre-recorded announcements. Recorded alerts can be automatically scheduled, increasing safety and communication for everyone on the grounds whilst minimising the work involved.

A choice of Bell System

Bodet can offer you two types of Bell System. Our Harmonys Bell System range runs across your IT network using Power Over Ethernet (POE) to power the system and enables users to broadcast live messages. It offers a unique customisable lockdown or panic alarm alert, differentiated from other broadcast alerts such as evacuations, fire alarms or daily events.

Harmonys range

These alerts can be triggered via a range of methods, such as wired multi-button control panel, wireless remote control, GSM signal or Harmonys Notify PC and smartphone app. This allows clear communication, improving the safety of both pupils and staff. We also supply connection to an induction loop with Harmonys Line, and Harmonys Trio/Flash units feature a visual alert indicator, ideal for the hard of hearing or for use in loud environments.

Our Melodys Bell System range is a wireless solution which means no cabling across equipment.

Hear from our customers

Djanogly Academy, St Francis Primary School and Blossom House School enhance punctuality and increase learning time in their school using Bodet's School Bell System:

Class changes are smooth and efficient and the corridors are empty by the time the music stops. The sense of urgency it instils has dramatically improved punctuality and avoids staff/student confrontation in the corridors, which has resulted in much better behaviour throughout the school.

The zoning facility is a real benefit to us. It means that we can make general announcements to the whole school, or we can send specific melodies or announcements just to the KS1 or the KS2 pupils. Each of the children and staff in the groups recognise their own sounds, so they know it applies to them, and it works very well.

We looked at several class change systems but decided that the versatility of Bodet Harmonys system means we can choose from a range of melodies or use the microphone to record our own announcements.
