The Model 391 Dante Alerting Unit builds on the limited capabilities of the "beacon" or a "strobe" devices that are ubiquitous with analog party-line (PL) intercom systems and adds a broad range of new and enhanced features. The Model 391 will respond to 20 kHz tone "call" signals that are commonly utilized in both legacy analog and modern digital party-line intercom circuits. Upon detecting a call signal the Model 391 can provide a visual indicator, enable an audible "buzzer" output, and even activate an analog 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. Typical Model 391 applications will include use in theaters, sports facilities, corporate events, and broadcast studios.
