Core Capabilities of the Bosch PVA-1WEOL

Explore the essential capabilities of the Bosch PVA-1WEOL for loudspeaker line supervision and integration with the PAVIRO system.

Loudspeaker Line Supervision

Monitors loudspeaker line integrity and detects open and short circuits through the PAVIRO EOL master.

Pilot-Tone Powered

Receives power directly through the loudspeaker line's pilot tone, eliminating the need for a separate power supply.

Multi-Module Support

Supports multiple supervision modules on one loudspeaker line, with up to 60 modules per amplifier output in compatible configurations.

PAVIRO System Integration

Integrates with the PAVIRO EOL master built into compatible controllers and routers for loudspeaker line monitoring.

DIP-Switch Addressing

Provides configurable module addresses through DIP switches, allowing the system to identify affected loudspeaker lines during faults.

LED Status Verification

The built-in status LED helps verify pilot-tone power and communication with the EOL master during installation.

Bosch PVA-1WEOL Installation & Connection Guide

The Bosch PVA-1WEOL connects to the PAVIRO loudspeaker line through dedicated speaker and ground terminals. Its DIP switches enable module addressing, while the integrated status LED helps verify power and communication with the EOL master.

01

Unique Module Address

Each module requires a unique DIP-switch address within its zone topology.

02

Earth / Ground Connection

Ground connection resistance should be below 1 kΩ for EOL master communication.

03

Cable Capacitance

Combined cable capacitance must remain within applicable system limits.

LED Status Reference

LED OFF

No voltage supply detected, for example when the pilot tone is disabled.

Slow Flashing — 2 Hz

Pilot-tone power is present on the loudspeaker line. The module is ready.

Rapid Flashing — 10 Hz

A valid EOL master command is received, indicated by a rapid flash every 40 seconds.

Installation Check: To activate the LED for five minutes, set switch 4 on DIP switch S2 to OFF and then back to ON.
