Sounder units are versatile devices that are most commonly used to indicate various states of operation for a device or installation or indicate warnings. They are audible signalling units that can indicate start, stop, fault signalling or call technical staff to quickly and easily signal when there is a problem or call to action which is especially important when visible signals can’t be seen in busy manufacturing or industrial environments. Sounders are a way of achieving maximum safety using high-frequency sound and can be used in combination with different frequencies and sirens to ensure the correct warning or signal message comes across. They are most commonly used in:

  • Industrial and manufacturing environments

  • Construction sites

  • Safety vehicles for traffic and law enforcement

  • Emergency vehicles

  • Public areas like offices, shops and housing blocks

What are the benefits of electronic sounders?

The main benefit of an electronic sounder beacon is that they provide critical audible communications in emergencies or to sound warnings that can prevent unplanned downtime, especially within industrial and manufacturing environments. By setting up an audible alarm tone, it can help prevent damage to expensive equipment, and even human injuries or fatalities, meaning a sounder is an essential piece of safety equipment in a wide range of environments and applications.
