At what voltage does the FVD audibly tone?

The FVD, or Fiber Voltage Detector, audibly tones at 50 volts. This feature is essential for technicians who work with fiber optics and electrical systems, as it allows them to quickly and safely identify live voltage in cables without direct contact. The reason for this specific voltage threshold is rooted in safety standards and practices; 50 volts is often considered a key level where electrical shock becomes a significant risk.

Additionally, targeting this voltage level ensures that technicians are alerted before encountering higher, potentially more dangerous voltages, thereby enhancing workplace safety. Recognizing the importance of audible alerts at this level helps technicians make informed decisions when working in environments where they might encounter live electrical systems. Understanding this function of the FVD is crucial for safe and effective field operations.
