Vocia PLD-2 Vocia Passive End Of Speaker Line Supervision Device (4-Pack)

Reliable Speaker Line Supervision for Vocia Amplifiers
The Vocia PLD-2 is a passive end-of-line supervision device designed for use with Vocia amplifiers, including the VA-4300CV and VA-8150CV. This essential component ensures continuous speaker line monitoring by detecting potential faults and disconnections, helping maintain the integrity of emergency paging and public address systems. Ideal for constant voltage applications, the PLD-2 provides a simple and effective solution for ensuring audio system reliability in mission-critical environments.

Seamless Integration with Vocia Amplifiers for Constant Voltage Systems
Designed to work with the VA-4300CV, VA-8150CV, and VA-8600 amplifiers, the PLD-2 integrates seamlessly into Vocia networked audio systems. The device requires no additional cabling and operates passively, reducing installation complexity while ensuring dependable speaker line monitoring. Whether deployed in large venues, corporate buildings, or life safety applications, the PLD-2 supports uninterrupted audio transmission by identifying potential issues before they impact system performance.

Pilot Tone Detection for Continuous Line Integrity Monitoring
Each Vocia amplifier uses a pilot tone to verify speaker line integrity, ensuring that every connected speaker remains functional. The PLD-2 is placed at the end of a non-branching speaker line, allowing the system to detect short circuits, open circuits, or other issues that could affect paging reliability. By continuously monitoring the system’s health, this device helps maintain consistent and clear audio output across all zones.

Broad Compatibility with Installed Loudspeakers
The PLD-2 is engineered for wide compatibility, working with most installed loudspeakers in constant voltage configurations. Its design supports non-branching speaker lines up to 4,300 feet (1,300 meters), depending on load and wire gauge. This flexibility makes it an ideal choice for large-scale installations that require robust and long-distance audio distribution.

Effortless Installation with Surface-Mountable Design
The PLD-2 is designed for easy installation, featuring a surface-mountable form factor that allows flexible placement in various installation environments. Because it operates passively, it does not require additional power sources, simplifying deployment and reducing system maintenance requirements. Its discreet design ensures it integrates seamlessly into existing speaker line infrastructure without requiring major modifications.

TAA Compliance for Government and Enterprise Applications
The PLD-2 meets U.S. Trade Agreement Act (TAA) compliance requirements, making it eligible for federal procurement and government contracts. It is a trusted solution for organizations that require a reliable and compliant speaker line monitoring system for emergency paging, mass notification, and public address applications.
