Record and store data
You can add a USB data logger to the sign to keep a record of noise levels in your workspace. You can programme the data logger to start recording at specific times and at various intervals over a day, a week, or longer. When you’ve finished recording your data, simply plug the USB data logger into your computer to download and view the measurements.
Need to cover a larger area?
No problem. You can connect the SoundSign to multiple Remote units using our unique Master and Remote system to show the same message as the ‘Master’ unit when triggered.
You can also connect the Master units to flashing xenon warning beacons to add extra visibility.
