The Model 391 Dante® Alerting Unit builds on the limited capabilities of the “beacon” or “strobe” devices that are ubiquitous with analogue party-line (PL) intercom systems and adds a broad range of new and enhanced features. The Model 391 responds to audio “call” signals that are present in the unit’s Dante audio input channels. With an 18-23 kHz detection range, it will detect tone call signals that are commonly utilized in both legacy analogue and modern digital PL intercom circuits.

Upon detecting a call signal the Model 391 can provide a visual indicator, enable an audio sounder output, and even activate an analogue line output. Each of the Model 391’s alerting resources can be individually optimized to meet the unique requirements of many applications. The STcontroller personal computer application is used to select from a wide range of operating choices. The compact, portable unit is compatible with Dante audio-over-Ethernet installations and requires only an Ethernet connection with Power-over-Ethernet (PoE) capabilities for operation. Typically applications will find the Model 391 applicable for use in theater, sports, and broadcast facilities.
