Bosch B820 Inovonics SDI2 Bus Interface Module

The Bosch B820 Inovonics SDI2 Bus Interface Module delivers seamless wireless integration for control panels, enabling you to extend security, surveillance, and monitoring capabilities without rewiring. As a Bosch-branded control panel module, the B820 links your panel to an Inovonics EN4200 EchoStream Serial Receiver and EchoStream wireless transmitters, providing a reliable, fully supervised SDI2 bus connection for consistent event reporting and faster diagnostics.

Designed for commercial, industrial, and institutional installations, the B820 supports up to 350 wireless devices (points and keyfobs combined) and can be installed up to 1,000 ft from the panel to optimize receiver placement and coverage. Its low 12V DC power requirement and modest 110 mA draw make it simple to integrate into existing security architectures while maintaining energy-efficient operation. Environmental ratings and RoHS compliance help ensure long-term, code-friendly deployments.

Use the Bosch B820 to expand wireless sensor networks, simplify retrofits, and strengthen monitoring strategies across campuses and multi-building sites. Contact your Bosch distributor or add the B820 to your next security system spec to increase wireless reach and reliability.
