BACring

Active fire protection technology

Fire safety regulations and the protection of building occupants require architects and planners to implement a reliable smoke damper control system. Such a system helps prevent the spread of smoke and fire through the building's ventilation network and supports safe building operation in the event of a fire.

Large buildings with up to 10,000 data points place high demands on a smoke damper control system.

To ensure maximum reliability, the system must handle large numbers of data points, support long communication distances, enable redundant network structures, provide response times in the millisecond range, and automatically detect and isolate faults.

Simple, robust, and comfortable

BACring is integrated with standard cabling and automatically identifies connected components during setup. The system is BTL-certified and BACnet-compliant, that is, compatible with the de facto standard bus system in building automation. The BACnet conformity has been BTL-certified.* The open structure makes the BACring expandable for future applications and supports data transmission to sensors and actuators from other manufacturers. The UL-prepared hardware is structurally open to future interface standards. BACring also proves to be pleasantly flexible when it comes to being integrated into dashboards of higher-level systems.

Advisory

New, but based on decades of experience

The implementation of BACring incorporated the experience that development engineers and programmers from BACring gained with the market-leading smoke flap control RKS1000^*, which has been in production since 1997.

The decision to develop BACring was made in order to meet current and future requirements for a modern, powerful, and flexibly expandable fire protection system. Because, in addition to the reliable monitoring of thousands of data points, BACring offers a wide range of interfaces for connecting to other building management systems as well as to widely used sensors and actuators from many manufacturers. This also includes the mapping of common BACnet functions.

Compatible

BACring is compatible with already installed modules such as RKS1000^*. This enables cost-saving partial modernization of existing fire protection systems: while modules continue to be used, the installed control panel is replaced with the BACring solution. This can update the overall system and allow for expandability for future needs.

The system is developed and produced in Germany.

Innovative with support

Of course, we have complete confidence in BACring and its capabilities. However, this powerful smoke damper control system is not only well received by us: its development is being funded under the Central Innovation Programme for SMEs (ZIM) by the Federal Ministry for Economic Affairs and Energy, based on a resolution of the German Bundestag.
