Bogen UTI312 Zone Paging Controller The Bogen UTI312 is a versatile and expandable zone paging controller designed for one-way paging applications such as those using self-amplified speaker systems. Ideal for educational, commercial, and industrial settings, the UTI312 supports up to 12 paging zones and can drive audio to as many as 150 self-amplified speakers per zone. Each unit includes a pre-installed ZX3 module offering 3 zones, and expansion is easy with additional ZX3 modules. The system features flexible zone grouping, multiple background music inputs, contact closures, and programmable features like override paging, night ringing, tone signaling, and code calling. Compatible with a wide range of analog telephone interfaces, the UTI312 is easy to set up and configure using DTMF programming, two-switch setup, and a microcontroller-based design. It’s a robust, scalable solution that simplifies complex paging needs with reliable performance.
