C-SV 20A and C-SV IB 20A control units command the smoke and the heat extraction in case of fire and also they allow daily ven-
tilation by opening a single or several windows. The control unit allows the connection of a wide range of sensors, rod actuators,
rack actuators and chain actuators and different accessories to complete the installation.
The control units are equipped with buffer batteries and they command 24 Vdc actuators. Smoke extraction opening occurs after
the enabling of smoke detectors, emergency push buttons, fire control units or "BMS - building management system" systems.
The emergency push buttons are equipped with LEDs for displaying faults and malfunctions of power supply and emergency status.
The control unit also allows natural ventilation by controlling automatically the windows depending on environmental conditions
detected by the sensors ensuring comfort and energy saving.
The manual control of windows and doors occurs by means of specific push buttons on two separate areas.
WARNING WARNING
The installation of the emergency push button is compulsory because, in addition to allowing manual emergency control, it also
provides display of fault / emergency warnings, and can be used for easy, remote RESETTING.
WARNING WARNING
The emergency commands enjoy priority over those for ventilation / climate control (the manual commands are blocked).
The control unit comes with 2 batteries that are kept charged when the mains power supply is available and, when this is not
available, they guarantee a 72 hour autonomy period in stand-by mode, making it possible to still execute a complete emergency
opening command, as prescribed by EN 12101-10.
Accessories and equipment connected to the control unit must be chosen among those listed in the following table and diagram:
