Intercom and Audio Paging Platform


The uCIOCOM is an installation-ready, board-level platform for IP voice and distributed audio communication including VoIP, intercoms, PA paging and mass notification. The system includes a host control protocol for integration and is compatible with the Mbarx ecosystem of tools and gateways for configuration and firmware management.

The device accepts PoE or 12VDC supply and supports amplified audio output of up to 5W (using PoE) and up to 15W using supply voltage. The board has isolated contacts and loop closures for connectivity to push-buttons, indicators, door controllers or other equipment.

The hardware supports an audio subsystem capable of supporting intelligibility and psychoacoustic enhancements including Acoustic Echo Canceller (AEC), Auto Gain Control (AGC), noise reduction and ambient noise compensation.

The uCIOCOM is available as part of a System Solutions engagement, packaged with development hardware, direct support, software customization and Mbarx reference code for host integration. System Solutions engagements help accelerate the creation of specialized voice communications products in buildings, transportation or healthcare environments, including access control, rescue assistance, nurse call and mass notification.
