1.1 General
Control unit FCLA-128, communication unit FCBA-2, and
relay unit FCFA-1 contain electronic components that can be
damaged if handled incorrectly. Before connecting power,
all external installations shall be completed.
Control unit FCLA-128, communication unit FCBA-2, and
relay unit FCFA-1 are mounted with 4 screws located under
the enclosure cover to ensure protection class IP54.
1.2 Inputs FCLA-128
Supply voltage AC 230 V 2 A, connectors L, N, and PE. Ex-
ample of electric cable type: EKK3G1,5
1.3 Outputs
All relay outputs are potential-free contacts shown in a
dead state.
ȱȱȱȱęȱȱǻȱǼȱȱ
the FCLA-128 are designed for 24 V, 3 A resistive load.
Summation alarm contacts for service alarm (marked SER-
VICE) in the FCLA-128 are designed for 24 V, 3 A resistive
load.
Relay contacts for interlocking of fans (marked FAN A and
FAN B) in the FCLA-128 are designed for 230 V, 3 A resis-
tive load. Example of electric cable type: EKK....
If you need more relay contacts for interlocking of fans, the
system can be expanded with relay unit FCFA-1.
1.4 Damper actuators
Damper actuators are connected to communication unit
FCBA-2; up to 64 actuators per loop with individual indica-
tion can be connected to the system, but max. two loops per
communication unit. Control unit FCLA-128 has two loops
available. For a complete system with 128 damper actuators
you must use both loops (Link 1 and Link 2).
Supply voltage to actuators 1 and 2 is connected in com-
munication unit FCBA-2 to connectors 1 and 2 (marked
MOTOR). Indications for closed damper are connected to
connectors S1 and S2 (marked MOTOR SWITCHES) and in-
dications for open damper to connectors S4 and S6 (marked
MOTOR SWITCHES).
S3 and S5 are not used and shall be insulated.
1.5 Smoke detectors
Smoke detectors are connected to communication unit
FCBA-2; up to 64 smoke detectors per loop with individual
indication can be connected to the system, but max. two
loops per communication unit. Control unit FCLA-128 has
two loops available. For a complete system with 128 smoke
detectors, you must use both loops (Link 1 and Link 2).
You can choose between three alternative smoke detectors
Siemens Rököga SOS2... or Calectro UG-3-... or Calectro
EVC-PY-DA.
When Siemens Rököga SOC2... is used, you can adjust the
sensitivity of the detector.
If you use Calectro UG-3-... smoke detectors, you must con-
nect the included 2.2 kohm resistor to the smoke detector
between connectors 1 and 5.
If you use Calectro EVC-PY-DA smoke detectors, you must
connect the 2.2 kohm resistor to the smoke detector between
connectors 1 and 3.
1.6 Operating of fans
Control unit FCLA-128 has two relay outputs (two groups)
for interlocking fans. For more relay outputs / groups, a re-
lay unit FCFA-1 must be connected. Up to eight relay units
can be connected to the system. (This means up to a total of
ten relay outputs/groups.)
1.7 Connecting communication to communication
unit FCBA-2
Control unit FCLA-128 has two connectors for connecting
communication wires between control unit FCLA-128 and
communication units FCBA-2 (LINK 1 and LINK 2). Max.
32 communication units can be connected to each commu-
nication loop.
Note! An individual address should be set for every com-
munication unit (FCBA-2) that shall be connected to the
control unit (FCLA-128) regardless of whether it is con-
nected to the LINK 1 or LINK 2 or not.
Type of electric cable:
ȱĜȱȱȬ ȱŘ¡Ř¡Ŗǯś
For industrial use ELAKY 2x2x0.6
1.8 Connecting communication to central control
and monitoring system
Control unit FCLA-128 has connectors for connecting com-
munication wiring (marked MODBUS slave) to a parent
system for control and monitoring.
1.9 External inputs
There are two inputs for external interlocking:
ȱȱ¡ȱęȱDZȱȱȱȱ¡ȱęȱǰȱ
dampers are closed and fan interlocking is activated, possi-
¢ȱȱ ȱ ȱȱ¡ȱęȱȱȱȱ
reset. These connectors are normally jumpered, and the
jumper is removed when this function is connected.
Input for external interlocking: Dampers are closed and fan
interlocking is activated. Normal status returns when the
interlocking is removed.
These connectors are normally jumpered, and the jumper is
removed when this function is connected.
1.10 Fan groups (zones)
To be able to interlock (stop) the fans in the system, the re-
lays in the control unit FCLA-128 must be activated (Groups
A and B), with Group A being preselected. If you need more
groups, you must connect relay units to the control unit,
which with max. 8 relay units per control unit will allow 10
relays (groups) for controlling fans.
All communication units in the system must have a desig-
ȱȱȱȱȱȱȱȱȱȱęǰȱȱ
-
cate damper faults, to indicate communication failures, and
to carry out damper testing.
