Control System FICO-128
6 Installing communication unit FCBA-2
Note! All installation work must be done with power to
the system disconnected.
On numbering of FCBA-2,
see Figure (page 7)
1
Connect power supply cables AC 230 V to communication unit
FCBA-2 according to high-voltage regulations.
1
2
Connect communication wiring to communication unit and fur-
ther on to next communication unit (FCBA-2) or control unit
(FCLA-128), with the loop connected in series and wires not
exchangeable.
7
3
Connect 24 V supply for damper motors to connectors 1 and
2, alternatively connect with quick couplings (motor wiring pre-
connected at the factory).
Connect damper motor limit position wiring to connectors S1,
S2, S4, and S6, or use quick couplings.
Wires 3 and 5 from damper motor are not used and must be
insulated.

4
Connect smoke detector
Siemens SOS2
... to connectors
G1/2, M1/1, and B1.
NOTE! Connect one smoke detector per input and max. two per
communication unit.

5
Connect Calectro EVC-PY-DA smoke detector to connectors
G1/6 and M1/3.
NOTE! Do not forget the end resistor between connectors 1
and 3 in smoke detector.
NOTE! Connect one smoke detector per input and max. two per
communication unit.

Connect
Calectro UG-3-
... to connectors G1/2 and M1/1.
NOTE! Do not forget the end resistor between connectors 1
and 5 in smoke detector.
NOTE! Connect one smoke detector per input and max. two per
communication unit.

7
Activate DIP switches of damper motors and smoke detectors
after connecting them in the communication unit (FCBA-2).
NOTE! Separate activation for left (L) and right (R) side of com-
munication unit.
(for example, if you have a damper motor connected, set the upper switch to ON).
(for example, if you have a smoke detector connected, set the lower switch to ON).
2
8
Set address using address switches for communication unit
(FCBA-2).
(for example, address 1 = 0 on the left and 1 on the right)
(for example, address 15 = 1 on the left and 5 on the right)
Address 01 will be shown first on display.
NOTE! An individual address should be set for every communication
unit (FCBA-2) that shall be connected to the control unit (FCLA-128)
regardless of whether it is connected to the LINK 1 or LINK 2 or not.

9
In the last communication unit /relay unit in each communication
loop, the end resistor must be activated. (LINK1 and LINK 2).
Set DIP switches 1 and 2 to ON.
