The UltraVoice® Remote Interface Controller, Model UVRI-B, establishes a communication link between an isolated location and Federal Signal’s Commander® alerting and notification system; creating a fully integrated indoor and outdoor Mass Notification System. UVRI-B’s primary application is to provide a communication bridge, allowing public safety official to expand their alerting and notification capabilities. The UVRI-B can interface with an individual buildings fire alarm panel, and is designed to provide remote control status and monitoring. The UVRI-B is a direct indoor replacement for the UVRI. 
Model UVRI-B can be equipped with a high capacity digital voice storage device for simple and/or complex voice messages.  When paired with Federal Signal’s Commander control system, UVRI-B offers the unique capability for a remote operator to record and broadcast urgent message notifications, or to activate VOIP communications. When local control and activations are required, the UVRI-B provides an easy to use local user interface with push button control for eight functions and a local microphone input for live voice announcements.
The UVRI-B has an IP interface that allows for simple high-speed two-way control and activation. Additionally, the UVRI-B can be equipped with two-way VHF/UHF radios, such as Motorola Vertex transceivers, for wireless communication to the Federal Signal Commander control system. The UVRI-B also supports cellular communication. UVRI-B utilizes secure digital data transfer methods via 128/256 bit encryption to ensure no malicious or accidental operation of the system. Status monitoring provides information on the following conditions: AC power, battery voltage, enclosure intrusion, charger, local activation, and remote system operation. It can also be configured to support Ambient Noise Monitoring utilizing  an external microphone for noise level detection.
The UVRI-B provides system maintenance improvements, an integrated IP interface, ambient noise level detection for automatic sound level adjustment, integrated 12VDC charger, simplified wiring, integrated speaker and an optional 100 watt amplifier. The speaker line is supervised when using distributed speakers.
