Information Pin 2:
If Pin 2 is changed from fire to smoke extraction application or from smoke extraction to fire application, the
FSC-UFC24 needs to be taken off the power supply and put back again to activate the new mode.
Information Pin 3:
When a FSC-UFC24 has been connected and operated in one bus protocol first (Modbus or BACnet) and then
will be operated by the other (BACnet or Modbus) the factory reset functionality in the FSC-UFC24 MUST be
activated by bus communication as soon as it is connected to the other protocol (Modbus register 33, BACnet
Object List BV 19).
If the FSC-UFC24 is used in connection with the FSC-M60, Pin 3 has to be on ON
(BACnet).
Information Pin 5:
If the FSC-UFC24 is used in connection with the FSC-M200, Pin 5 has to be on ON (Baud Rate 38400).
Explanation Pin 7:
• Smoke Detector Alarm “System” = The signal of the smoke detector is transferred directly to the system
and processed there.
• Smoke Detector Alarm “Actuator“ = The signal of the smoke detector is directly linked with the actuator.
In case of a smoke detector alarm the fire damper connected to the same FSC-UFC24 will be closed. The
signal of the smoke detector is forwarded to the controller.
The above is only valid for the fire safety application. In the smoke extraction application the signal of the
smoke detector has no direct influence to the actuator. The signal will be forwarded to the system in any case.
Baud Rate Selection Modbus
This has to be done when choosing Modbus only.
