Speech Intelligibility Testing

Fire safety should never be taken for granted, no matter what kind of business you run or how big your location (or multiple locations) are. Having an effective, accurate fire safety system is vital, and you need a reliable way to make sure that it works. You also need to know that your systems voice is clear and easily understood, making sure that all your staff at your location are able to hear and understand it when time and safety is a factor. SDi Fire offers a variety of detector testers for this very purpose – to test just how clear and easy-to-understand your emergency voice system is.

VOX

VOX (VOX01)

The VOX VOX01 is a universal, easy to use speech intelligibility tester for your fire safety system.

The VOX01 is designed primarily for ease-of-use, with a simple, user-friendly touch screen for precise and basic control. The unit is also equipped with a USB port to provide fast and versatile connectivity to your network. Additionally, the unit includes a custom hard case for its own protection, making sure it is kept safe and in working condition.
