Universal brake system for fire protection closures. Thanks to the high protection class IP 65 the VdS-tested and approved RZ8 brake system can be used almost anywhere. It stands out thanks to its clear operating and display membrane and allows the connection of a reporting line with up to 20 fire detection elements. Otherwise, the RZ8 is also extremely flexible and offers connection options for almost all standard brake units, fire detection systems and drives by various manufacturers. Optional powerpacks can also bridge brief power failures.
