Thank you for buying this product. Our company is sure that you will
be more than satisfied with the product's performance.
Carefully read the "INSTRUCTION BOOKLET" which is supplied
together with this product, since they provide important infor-
mation regarding the safety, installation, use and maintenance
of the product.
This product complies with recognised technical standards and safety
regulations. We declare that this product is in conformity with the
following European Directives: 89/336/EEC, 73/23/EEC.
This is a type C device according to EN12453-5.5.1, and it only com-
plies with the 98/37/EEC directive when it is connected to a control
panel from the same manufacturer, provided with a fault-finding
circuit in safety circuits, and to a conforming sensitive element. In
the case where the fault-finding circuit in safety circuits is not used,
get qualified personnel to check the device function at intervals not
longer than 6 months.
WARNING
For wiring and installation operations, refer to current standards and
also to good technical practice.
1) GENERAL OUTLINE
This board can be used in the safety devices which have a resi-
stance of 8200 Ω at rest. When the device is stressed or when
there is a fault in the wiring cables (short circuit or open circuit), the
equivalent resistance changes and this causes triggering of the
board output relay, which changes status.
The safety device having these characteristics (8200 Ω resistance
at rest) must be in conformity with the EN 954-1 standards for ca-
tegory 2. The board is provided with a fault-finding system. Correct
operation is only guaranteed if it is connected to appropriate BFT
control units.
FLC 8K2 is a safety device which can be used on sliding and swing
gates, roll-up doors, sliding and sectional doors.

To connect the control units from the same manufacturer, provided
with a fault-finding circuit in safety circuits, refer to the connection
diagrams for the devices tested, which are contained in the control
unit manual. In the connection diagrams for the devices tested, the
devices tested are shown as an RX/TX pair, the terminals of RX
correspond to those of FLC8k2, terminal 1 of TX corresponds to
terminal 6 of FLC8k2, and the connection for terminal 2 of TX is
not to be carried out. In the case where the fault-finding circuit is
not used in safety circuits, make a wire bridge between terminals 1
and 6 of FLC8k2, and get qualified personnel to check the device
function at intervals not longer than 6 months.
Moreover, protect the cables along their entire length (for example
by inserting them in raceways).

4) INSTALLATION
Before carrying out any connections, check the diameter of the sen-
sitive element connection cable. If necessary, replace the rubber cap
(Fig. 4-7). Warning: do not forget to fit the O rings (Fig.7). The
FLC 8K2 device can be housed under the cover of the control unit
box (Fig.10) or mounted on the wall by means of the clip supplied
or a clevis for rigid pipes. If adequately-sized pipes are available for
passing the cables through, FLC 8K2 can be inserted inside these
pipes.
WARNING!
Correct operation is only ensured when the data contained
in the present manual are observed. The company is not to
be held responsible for any damage resulting from failure to
observe the installation standards and the instructions con-
tained in the present manual.
The descriptions and illustrations contained in the present
manual are not binding. The Company reserves the right to
make any alterations deemed appropriate for the technical,
manufacturing and commercial improvement of the product,
while leaving the essential product features unchanged, at any
time and without undertaking to update the present publica-
tion.
