Bosch PVA-1WEOL End-of-line Supervision Module

Ensure reliable audio and safety communications with the Bosch PVA-1WEOL End-of-line Supervision Module. Designed for Pro Mass Notification and installed in PAVIRO systems, this EOL supervision module continuously monitors loudspeaker line integrity to detect opens and short circuits, reducing downtime and preserving both business music and critical announcement paths. The module works with 100 V, 70 V or 50 V loudspeaker lines and is powered via the loudspeaker pilot tone, eliminating the need for separate power wiring and simplifying installation. A visible status LED lets technicians quickly verify installation health on site, while the ability to connect up to 60 modules to one amplifier output channel makes the device ideal for scalable deployments in campuses, transportation hubs, retail and industrial facilities. EN 54-16 system certification provides certified performance for safety-critical applications. Integrate the Bosch PVA-1WEOL into your security and monitoring strategy to enhance surveillance, mass notification and operational continuity.
