- Page 3 All locally valid regulations and requirements must be observed. Product Features / Application The FSC-UFC24 is used together with a fire or smoke extraction damper actuator to control and monitor one fire or smoke extraction damper. It offers Modbus, BACnet or analog connection and is normally mounted at or close to the damper.

Page 10: Connection Details
Smoke Extraction Damper Actuator – Connections If the actuator is powered up the smoke extraction damper is either open or closed. If the FSC-UFC24 sends the smoke extraction damper actuator the open signal, pin OPEN is powered. If the FSC-UFC24 sends the smoke extraction damper actuator the close signal, pin CLOSE is powered. - Page 11 Technical Data Sheet FSC-UFC24 Thermoelectric Tripping Device - Connection Digital input volt free, normally close as default (can be changed on bus). Factory shorted. When this input is active the damper will close and you can override from the bus.

There is one input to open or close the damper, depending on the fire or smoke extraction application. It is also possible to monitor the damper position conventionally through a digital output signal.

Page 18: Bus Monitoring Application
Bus Monitoring Application The FSC-UFC24 is equipped with a Bus Monitoring Function. If the bus signal to the FSC-UFC24 is interrupted the damper will move to the safety position after the defined period of time and remain there until the bus functionality is back to normal operation.
