Alertz for Schools | Because Silence is Golden, Especially in Classrooms
Less noise. More room to learn.
Create a calmer, more focussed learning environment with Alertz®, an electronic classroom noise management system that helps pupils recognise and manage their own noise levels.
Using a simple traffic light system, Alertz® provides instant visual feedback as classroom noise increases. Green indicates an acceptable noise level, amber signals that the volume is rising, and flashing red shows when the selected noise limit has been exceeded.
Rather than relying on repeated verbal reminders, teachers can use Alertz® to encourage pupils to take greater responsibility for their own volume, supporting positive classroom behaviour and a more settled learning environment.
With seven adjustable noise sensitivity levels, Alertz® can be tailored to different activities and environments, from quiet independent work to group discussions. Optional audible alerts and personalised recorded messages provide additional flexibility, allowing teachers to choose the approach that works for their pupils.
Ideal for classrooms, assembly halls, dining areas, libraries and other shared spaces, Alertz® provides a practical, highly visual way to support noise awareness throughout the school day.
Features & Benefits
A simple visual reminder everyone can understand.
The intuitive green, amber and red traffic light system gives pupils immediate feedback on classroom noise, helping them recognise when they need to adjust their volume without constant verbal reminders from teaching staff.
The right noise level for every activity.
Seven adjustable sensitivity settings allow teachers to establish appropriate noise levels for different learning environments, from quiet reading and independent work to collaborative classroom activities.
Encourages independence and self-regulation.
By making noise levels visible, Alertz® provides pupils with a clear reference point, encouraging them to monitor their own behaviour and take greater responsibility for maintaining a positive learning environment.
Personalised reminders, delivered consistently.
Choose between visual alerts, an optional siren or one of four personalised pre-recorded messages or sounds. Teachers can select an approach that suits their classroom and adjust the volume using the infrared remote control.
Less interruption. More time for teaching.
Alertz® provides a consistent visual reminder when classroom noise rises, helping reduce the need for repeated verbal instructions and allowing teachers to maintain the flow of their lessons.
Understand how often noise limits are exceeded.
A built-in digital counter records each time the red light is activated, providing a simple way to monitor noise-level incidents and review progress over time.
Flexible enough for the whole school.
Suitable for classrooms, libraries, assembly halls, dining areas and corridors, Alertz® can be positioned on a table or shelf or mounted on a wall. Mains and battery power options provide additional flexibility.
