BBR VT CONA CMX

The newly developed BBR VT CONA CMX family has been tested to the most stringent international testing specifications – those of the European Assessment Document EAD16 (former ETAG 013). Its modular design means that a CONA CMX PT kit can easily be configured to match special requirements. All systems are subject to Factory Production Control (FPC), as well as independent and continuous surveillance. All CONA CMX kits must be installed by trained BBR PT Specialist Companies only, ensuring a professional and system-conforming installation. All requirements are strictly followed by the BBR Network and ensure the highest level of product quality and installation, including best health and safety standards.
