remotely – by actuation of the axial electric actuator with a return spring. The dampers automatically closes after activation of thermoelectric release or after the supply voltage disappears. remotely – by actuation of the axial electric actuator without a return spring after applying voltage to the appropriate contact. After widespread of the fire, the damper closes after activation by the building fire protection system, by applying voltage to the appropriate contact of the damper.If dampers remain open during normal operation (safety position – air transfer), closing them takes places:automatically – by actuation of the thermoelectric release  manually – by pressing the control button on the thermoelectric release remotely – by actuation of the axial electric actuator with a return spring as the supply voltage disappears remotely – by actuation of the axial electric actuator without a return spring after applying voltage to the appropriate contact.
