Description

This noise warning sign is there all the time, so you don’t have to be. It is ideal for use in environments where maintaining quiet is essential. The SafeEar Noise-activated Warning Sign is perfect for offices, call centres, classrooms, exam rooms, corridors, hospitals and libraries, where it gives a clear visual alert when background noise becomes too high.

By setting the PulsarSafeEar to trigger at a lower threshold, it helps ensure that noise levels remain within acceptable limits and reminds people to keep the environment calm and quiet.

 

Link Multiple SafeEar Units for Wider Visibility

Link your SafeEar Master to additional Remote Display Units to extend coverage across larger areas and ensure more people see the alerts. This setup also allows different noise warning messages to be shown in multiple languages, making it easy to communicate with a diverse workforce.

 

Language Options & Custom Designs

The SafeEar Noise-activated Warning Sign is available in the following languages as standard:

  • English
  • German
  • French
  • Spanish

 

The SafeEar is available in other languages upon request. Custom design options are also available, which can include your company’s branding. Please contact us for more details.

 

Capture Noise Level Measurements Easily

The SafeEar Noise-activated Warning Sign can be upgraded to become a data logging unit by adding the SafeEar Data Logger and USB software.

Instructions

The sections below outline the basic operation of the SafeEar Noise-activated Warning Sign. For full instructions, please refer to the user manual.

 

Setting the Trigger Level and Brightness

The trigger level and display brightness are adjusted using the dials on the back of the unit, behind the cover. Remove the cover using the provided screwdriver. The trigger level can be set between 40 dB(A) and 120 dB(A). This level is measured at the microphone position, so take into account any distance between the noise source and the microphone.

To disable the 30-second turn-off delay, add โ€œ800โ€ to the dB setting. For example:

085 = 85 dB(A) with 30-second delay

885 = 85 dB(A) with no delay

The brightness can be adjusted between 0 and 9 to suit the environment using the top dial.

 

Installing the Pulsar SafeEar

The SafeEar is quick and easy to install. Use the paper mounting template found in the user manual to mark the correct spacing for the wall fixings. Drill two holes, insert the wall plugs, and secure the screws, leaving a small gap for the unit to slide into place. Once the screws are fitted, align the holes on the back of the SafeEar with the screws and gently slide the unit down into position.

 

Connecting the Power

Plug the power cable into the Power In socket and connect the mains adapter to a suitable outlet. The SafeEar will now automatically illuminate when the noise levels exceed the selected trigger level.

 

Connecting a Remote Display Unit

The SafeEar Master can be used with up to three optional Remote Display Units to extend visibility. Connect the supplied cable between the Power Out socket on the Master Unit and the Power In socket on the Remote Unit. When multiple Remote Units are required, link them in sequence by connecting the Power Out socket of one Remote Unit to the Power In socket of the next. All connected displays will illuminate when the Master Unit detects noise above the trigger level.

Mount each Remote Unit securely using the wall-mounting template and the provided fixings. Ensure that all cables are firmly connected and routed safely before powering on the system.

 

Optional Data Logger

An optionalย SafeEar Data Loggerย is available that allows you to store and review noise measurements made by the SafeEar. To use the data logger, install the SafeEar Software on your PC and follow the instructions provided in the user manual.

Applications

The SafeEar Noise-Activated Warning Sign provides a clear visual alert when noise levels exceed a pre-set threshold, providing a clear visual reminder to reduce noise to acceptable levels.

 

Classroom Noise

In educational settings, the SafeEar helps maintain a calm and focused learning environment. When noise rises above the chosen trigger level, the sign illuminates to remind students and staff to lower their voices. This simple visual alert supports better concentration, reduces stress for both teachers and students, and helps prevent the escalating noise levels.

 

Hospital Noise

In hospitals and healthcare settings, the SafeEar Noise-Activated Warning Sign helps reduce excessive noise that can disturb patients and impact recovery. When noise exceeds the chosen trigger level, the sign illuminates to remind staff and visitors to lower their voices and reduce background noise. Excessive sound levels are common in wards, intensive care units, and neonatal units, where alarms, equipment, and staff often push noise levels above limits recommended by the World Health Organization. By providing a visual reminder, the SafeEar helps maintain a calmer, more restful environment, promoting faster recovery and patient wellbeing.

 

Office and Call Centre Noise

In offices and call centres, the SafeEar helps create a quieter, more productive workspace. When background noise exceeds the chosen trigger level, the sign illuminates to remind staff to lower their voices. Excessive noise is a common cause of distraction and stress in busy workplaces, often leading to reduced concentration, communication issues and lower job satisfaction. By providing a simple, visual alert, the SafeEar encourages awareness of noise levels and supports employers in promoting wellbeing, productivity and a more positive working environment.
