The modules clima BSK4-F and clima BSK4-F230 are used as actuators to integrate up to 4 fire dampers or smoke dampers with spring return drive into LON networks. The difference between both types of modules is the type of power supply. The module clima BSK4-F is supplied with 24V AC or DC, the module clima BSK4-F230 is mains-operated (230V AC). The damper motors could be directly connected to the terminal blocks of the modules.
Both modules support a monitoring of 8 potential-free end-position switches. LED indicators provide a status information about the actual status of the end-position switches and therefore the damper position. The switch outputs can drive the damper motors to set the damper in normal position.
The application provides for each connected damper a functional block according to LonMark™ profile „FireSmokeDamperActuator“ (#11001_10). The current damper position is transferred via the LON-network. A damper maintenance routine is integrated in the application. By measuring the damper driving time which is needed to move from one end-position to the other, mechanical failures could be easily detected. The application provides detailed alarm messages regarding triggered fire alarms of damper malfunction. Those messages can be signalled to a building management system via the LON network.
