The KSUB is available as a standalone unit, when it can handle up to four dampers in two groups. The unit can cover two fire zones and damper exercises can be carried out in sequence. There is an output for locking the ventilation system. The damper exercise timer is preset to 48 hours. In night mode, the KSUB is controlled from the KSUA but can also support a local fan controlled by an external timer.
KSUB is available in a light version. This version is without the analog detector circuits.

The KSUC is designed to work with the KSUA in a network. The KSUC receives alarm signals from smoke detectors in external fire alarm systems. These fire zones can then be defined in the KSUA to close dampers, etc. 16 fire zones can be handled in the KSUC.

KSUE is a control and monitoring unit for controlling various types of fire / smoke dampers. KSUE can be connected via a network to KSUA but can also be used completely standalone. 8 damper inputs and four detector groups exist. These can then be grouped into one or four fire zones. Each gate input and detector block are individually manageable. To KSUE can be connected air handling units for interlocking. KSUE also has input for external alarm and night operation.
