Description
Bosch PRA-EOL-US PRAESENSA End of Line Device for Loudspeaker Line Supervision
The Bosch PRA-EOL-US is an essential end-of-line device engineered to ensure reliable loudspeaker line integrity supervision in emergency sound systems. Designed to connect at the terminal end of a loudspeaker line, this compact device communicates directly with PRAESENSA amplifiers to continuously verify line integrity even in complex installations. Where standard impedance measurements may fail to accurately detect subtle line faults, the PRA-EOL-US provides a trustworthy monitoring solution through advanced high-frequency pilot tone technology.
The compact housing design allows the PRA-EOL-US to fit seamlessly within most Bosch loudspeaker enclosures and junction boxes, eliminating the need for additional mounting hardware or extensive modifications to existing installations. This device excels in supervising long loudspeaker runs where maintaining line integrity is critical for life-safety compliance. The integrated fault detection system identifies amplifier and line issues without requiring extra wiring, simplifying installation procedures and reducing system complexity. Multiple mounting provisions offer flexible positioning options, ensuring reliable operation in diverse emergency sound system configurations.
