DESCRIPTION

By installing the VA-EOL end of line supervision board, the system can adapt the changing impedance when adjusting multiple VAT volume attenuators without loopback cable, and use time-sharing which approaches to detect open or short circuit for each branch. The system can indicate which speaker line is open/short circuit within 90 seconds (EN54-16 requirement), helping to save the analysis time.

FEATURES

• Monitor the status of the loudspeaker line and all of its branches without additional loopback cabling.
• Detect if there's speaker line short circuits or open circuits faults by monitoring the terminated resistance value.
• Compatible with 100V and 70V loudspeaker lines.
• The VA-EOL is mounted inside the case of the last loudspeaker on the loudspeaker line.
