FSC-UFC24
FSC-UFC24
120Ω at 1 Mhz. Made of 24 # flexible twisted pairs
overall foil + braid shielded and overall jacketed with a
flexibel compound for indoor use.
The shield is connected in between the wires
but not connected to the FSC-UFC24.
The shield is connected to KNOWN/TESTED GROUND
at one point in one line (no matter middle or end).
Shield is not
connected
Up to 1’200 meters and max. 100 FSC-UFC24 with Modbus RTU and 65 FSC-UFC24 with BACnet MS/TP
Wires are interconnected between them and then
inserted to the terminal.
Control
Conventional
The FSC-UFC24 offers 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 fire 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.
Communication
Serial Communication – RS-485
Through Modbus RTU (RS-485) or BACnet MS/TP (RS-485).
Actuator Connection
3-pole AMP plug and terminal connection for standard 24 V AC/DC fire
or smoke extraction actuator.
6-pole AMP plug and terminal connection for 2 internal actuator end
switches. Identification of the end position switches of the actuators.
Additional Connections
Input Modules
2-pole AMP plug and 3-pole connection (terminal) for thermoelectric
tripping device. Dry contact input.
4-pole connection (terminal) for smoke detector (incl. power supply).
Dry contact input. Digital input for analog application.
Output Module
1 analog output, indicates the status of the FSC-UFC24.
120Ω at 1 Mhz. Made of 24# flexible twisted pairs overall foil +
braidshielded and overall jacketed with a flexible compound for indoor
use, or similar. Cable type: Belden 3105a or equivalent.
IMPORTANT:
SMT takes no responsibility of the functionality of the
units/network if a different cable is used to the one specified here.
