Product Description

The Bogen UTI312 is a multi-zone universal telephone interface designed to provide seamless integration between a telephone system and a public address (PA) or paging system. It enables paging, signaling, and music on hold functions through virtually any PABX, electronic key system, or 1A2 key system. The UTI312 features 12 contact closure outputs, allowing for multi-zone paging capabilities, and offers adjustable volume controls for voice and music, as well as an automatic level control (ALC) for consistent voice output. It supports various loop start, ground start, and station port (90V ring) interfaces, making it highly versatile for different telephone systems. Its robust design and comprehensive features make it an ideal solution for offices, schools, and commercial facilities requiring flexible and reliable paging over their existing telephone infrastructure.
