Installation The FSC-UFC24 is directly installed at or close to the re or smoke
extraction damper. The bracket can be pre-installed. The FSC-UFC24 can
be snapped onto the bracket any time (at the damper manufacturer or
at the job site).
Electrical Installation See details page 7.
Safety Notes The FSC-UFC24 is not allowed to be used outside the specied eld
of application, especially in aircraft or in any other airborne means of
transport.
The company buying and / or mounting the FSC-UFC24 on site bears
full responsibility for the proper functioning of the whole system. Only
authorized specialists may carry out the installation. All applicable legal
or institutional installation regulations must be complied with during
installation.
The device contains electrical and electronic components and is not
allowed to be disposed of as domestic refuse. All locally valid regulations
and requirements must be observed.
Product Features / Application The FSC-UFC24 is used together with a re or smoke extraction damper
actuator to control and monitor one re or smoke extraction damper. It
oers Modbus, BACnet or analog connection and is normally mounted at
or close to the damper. Following control modes can be chosen through
dip switch terminal:
  •Fireorsmokeextractionapplication
  •Busprotocols:ModbusorBACnet
Conventional: Analog output and digital input signals for conventional
application.
This digital input in the FSC-UFC24 always overrides the bus commands.
Universal System Link between re or smoke extraction damper and any
Modbus or BACnet system or analog control.
Power Supply The FSC-UFC24 needs to be powered up with 24 V AC / DC. The
FSC-UFC24 provides the power supply to the actuator and to other
connected devices (e. g. smoke detector). For more details see page 7.

Control Conventional
The FSC-UFC24 oers the option to work without the bus
communication (Modbus / BACnet) and can be controlled in a
conventional way. There is one input to open or close the damper. The
home position is depending on the re or smoke extraction application.
It is also possible to monitor the damper position conventional through
a digital output signal.
There is one analog output to signalize the status of the FSC-UFC24 and
the actuator. This analog output can be read from any controller.

General Information
Main Power – FSC-UFC24
The FSC-UFC24 is dual power 24V AC/DC.
The actuator has to be 24V AC and/or DC. Meaning it has to operate with the same voltage (AC or DC) as the
FSC-UFC24. There are 2 terminals for the power, in order to make the daisy chain connection for the installer
easier.
The polarity must be respected when connecting multiple FSC-UFC24 to one power source
(phase to phase, com to com)!

Information Pin 2:
If Pin 2 is changed from re to smoke extraction application or from smoke extraction to re application, the
FSC-UFC24 needs to be taken o 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 rst (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 re 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 re safety application. In the smoke extraction application the signal of the
smoke detector has no direct inuence to the actuator. The signal will be forwarded to the system in any case.

The FSC-UFC24 has the option to work without the bus communication connected. There is one input to
open or close the damper, depending on the re or smoke extraction application. It is also possible to
monitor the damper position conventionally through a digital output signal.
The analog output, signals the status of the FSC-UFC24:
• 0V – No Power to FSC-UFC24
• 2V – Damper Open
• 4V – Damper Close
• 6V – Smoke Detector Alarm
• 8V – Thermoel. Tripping Device Alarm
• 10V – More than one Alarm Condition
During normal operation this output will signalize the position of the damper (2V, 4V).
This output can be connected in parallel between the various FSC-UFC24 in order to monitor their status.

Depending on the application (re or smoke extraction) the test button creates dierent test scenarios.
Fire Application:
• Power on the FSC-UFC24: actuator (damper) opening until end position is reached
• Pushing test button will interrupt the power supply to the actuator. Spring is closing the actuator
• As soon as the test button is released the power comes back to the actuator and the damper will open again
Smoke Extraction Application:
• Power on: actuator makes self-test and remains in position dened by controls
• Pushing test button changes command of the actuator – actuator (damper) runs into opposite direction
• Release test button: actuator (damper) runs back into last dened position
Functionality of Test Button

The FSC-UFC24 is equipped with an actuator run time monitoring function. This function monitors the time
required by the actuator from leaving of the one and reaching of the other end switch. If the actuator does
not reach the other end switch in the specied time an error message is sent.
The default value for the actuator run time is 90 seconds. This can be adapted via Modbus or BACnet from
0…360 seconds.
The FSC-UFC24 oers a‘Full Auto Test’ function. This can be controlled through the Modbus or BACnet
controller.
Basis of the Functionality
Basis for this function is the run time monitoring of the actuator.
Fire Damper
To start the full auto test functionality, the corresponding bus-register hast to be activated via bus. By starting
the full auto test, the timer of the run time monitoring starts to count the time and the re damper actuator is
closing (spring) and remains in the closed position until the timer of the set running time has reached the set
time. Then the actuator will open again automatically until the end switch has been reached. The timer of the
run time monitoring starts to count again as soon as the command ‘open’ has been sent. Once the timer of
the set running time has reached the set time, the FSC-UFC24 will go back into normal operation mode and a
feedback ”full auto test ok” is activated. If one of the end switches is not reached within the dened running
time, an error message is activated.
Smoke Extraction Damper
To start the full auto test functionality, the corresponding bus-register has to be activated via bus. By starting
the full auto test, the timer of the run time monitoring starts to count the time and the smoke extraction
damper actuator is moving to the opposite direction and remains in that position until the timer of the
set running time has reached the set time. Then the actuator will automatically move back to the original
position until the end switch has been reached. The timer of the run time monitoring starts to count again as
soon as the command ‘opposite direction’has been sent. Once the timer of the set running time has reached
the set time, the FSC-UFC24 will go back into normal operation mode and a feedback ”full auto test ok” is
activated. If one of the end switches is not reached within the dened running time, an error message is
activated.

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 dened period of time and remain there until the bus
functionality is back to normal operation.
Objects
There are 2 objects which can be activated by Modbus or BACnet:
• Logic Alarm / Bus Monitoring Function
• Logic Alarm Delay / Set Delay (time in sec)
Default settings:
Logic Alarm / Bus Monitoring Function not active
Activation (via Bus):
• Logic Alarm / Bus Monitoring Function 1 (on)
• Logic Alarm Delay is activated, default delay time is 120 sec. Option to set the delay time via bus between
30…360 sec
Functionality
Fire Damper
After the dened period of time the re damper will move to the closed position and remains closed until the
bus functionality is back to normal operation.
Smoke Extraction Damper
If the smoke extraction damper is closed:
After the dened delay the smoke extraction damper will move to the open position and remains open until
the bus functionality is back to normal operation.
If the smoke extraction damper is open:
The smoke extraction damper remains in the open position even if the bus signal is interrupted.
