Biamp Vocia ELD-1
Vocia End-of-Line Supervision Device
The Vocia ELD-1 is an end-of-line supervision device used to monitor the integrity of constant-voltage loudspeaker lines in Vocia paging and voice evacuation systems. Installed at the far end of a speaker circuit, it enables the system to detect line faults such as open or short conditions, so problems can be reported before they compromise critical announcements.
Line supervision is a cornerstone of dependable emergency sound and mass notification, where every zone must be verified as ready to deliver messages. By providing a reliable end-of-line reference for fault detection, the ELD-1 supports code-aware system designs and gives facilities managers confidence that loudspeaker circuits are continuously monitored as part of the wider supervised Vocia architecture.
