Safety
• Control system for smoke ventilation
KFX 210/211/212/213/214 and control unit for
smoke ventilation KFC 210/220 can be used by
persons (aged 8 years and above) with sufficient
experience and knowledge if they have been given
instruction concerning safe use and understand
the hazards involved. Cleaning and user mainte-
nance must not be made by unsupervised chil-
dren.
• Children must not play with the control system.
• The installer must instruct the owner in the
function of the control system including reset-
ting of alarms and position of data plate and
instructions.
• The data plate is placed in the control unit.
• When resetting alarms, be sure not to touch
conductive parts and make sure that no body
parts can get caught in the window when reac-
tivated.
• WARNING! Make sure to use ESD protection
when touching the printed circuit board for
example during installation and service.
Important information

VELUX®5
Product
• The control system has been designed for use with genuine VELUX prod-
ucts. Connection to other products may cause damage or malfunction.
• The control system is in conformity with the Low Voltage Directive and
the EMC Directive for use in household, trade, industry and light industry.
• When installed, the control system complies with protection degree
IP 42.
• The control system can operate smoke ventilation windows with a total
power consumption of 10 A (KFC 210) and 2 x 10 A (KFC 220) respec-
tively.
• The packaging must be disposed of in accordance with national regula-
tions.
• Products, including batteries if any, marked with the crossed out
wheeled bin are regarded as electrical and electronic equipment and
contain hazardous materials, components and substances. The crossed
out wheeled bin symbolises that electrical and electronic equipment
waste must not be disposed of together with household waste. It must
be collected separately at recycling stations or other collection sites or
retrieved directly from households to increase the possibilities of recyc-
ling, reuse and utilisation of electrical and electronic equipment waste.
By sorting electrical and electronic equipment waste with this symbol,
you contribute to reducing the volume of incinerated or buried waste and
to reducing any negative impact on human health and the environment.
Further information can be obtained from the local municipality's techni-
cal administration or from your VELUX sales company.
• If batteries can be removed, product and batteries must be disposed of
separately.
Installation
• Installation must be carried out by a certified person in accordance with
current national regulations.
• The control system must be connected directly to the mains supply in ac-
cordance with national regulations. Ensure that the mains supply cannot
be disconnected unintentionally. It is recommended that disconnection
is only possible using the mains switch or a key switch. At least one of
these means for disconnection must be incorporated in the fixed wiring in
accordance with national wiring requirements.
Maintenance and service
• Disconnect mains supply and back-up batteries before carrying out any
maintenance or service work to the control system and ensure that they
cannot be reconnected unintentionally during this time.
• The control system must be tested after installation, service work and
alterations to the system. It must be inspected by qualified personnel at
least once a year. Tests and inspections must be documented in accord-
ance with national regulations.
• At the yearly inspection, the connected products must be checked ac-
cording to their instructions.
• The printed circuit board monitors the time between inspection periods.
If more than 15 months have passed since the last inspection, the yellow
light-emitting diode is on and an acoustic alarm sounds.
• The batteries must be checked at the yearly inspection. We recommend
that the batteries are replaced at least every four years.
• If you have any technical questions, please contact your VELUX sales
company, see telephone list or www.velux.com.

Up to 10 break-glass points can be connected
to each control system.
Installation
Break-glass points KFK 100/101/102/103/104
are surface mounted and should be connected in
accordance with current national legislation. The
installation surface must be smooth and level.
Connection
The break-glass point is connected to the
control unit by means of a 6-core cable with a
minimum cross-section of 0.5 mm2. This cable
can be up to 100 m long.
Break-glass points KFK 100/101/102/103/104
must be installed in continuous single line con-
nections to ensure that the complete line from
the control unit to the last break-glass point
is monitored. Individual connection to more
than one break-glass point does not allow for
monitoring.
The first additional break-glass point must be
connected to the terminals in the control unit.
When connecting, lead cable through the rub-
ber membrane and fasten with cable tie.
Terminal module J1 (jumper)
Terminal module J1 in the control unit must be
moved to the last or only break-glass point – ie
to the break-glass point placed farthest away
from the control unit a.
Note: If no break-glass points are in the
system, the terminal module in the control unit
must be moved from the middle and lowest pin
to the top and middle pin b.
Colour of frame for break-glass point in
control unit
The white frame can be replaced by the
coloured frame supplied (applies to KFX 211,
212, 213 and 214 and KFC 210 and 220). See
page 32.

Up to 10 smoke detectors can be connected to
each control system.
Installation
Smoke detector KFA 100 should always be
fitted on the ceiling in accordance with current
national legislation. After fitting the base, the
smoke detector can be snapped into place.
Position dust cover over the smoke detector
until it is ready for operation.
Connection
The smoke detector is connected to the control
unit by means of a 2-core cable with a mini-
mum cross-section of 0.5 mm2. This cable can
be up to 100 m long.
Smoke detectors KFA 100 must be installed
in continuous single line connections to ensure
that the complete line from the control unit
to the last detector is monitored. Individual
connection to more than one break-glass point
does not allow for monitoring.
When connecting, lead cable through the rub-
ber membrane and fasten with cable tie.
Terminal module in control system
The terminal module in the control unit must be
moved to the last or only smoke detector – ie to
the smoke detector placed farthest away from
the control unit.

The product can be purchased separately.
Note: When fitting rain sensor KLA 200, use
the instructions supplied with the sensor.
Connection
The rain sensor is connected to the control unit
by means of a 3-core cable with a minimum
cross-section of 0.5 mm2. This cable can be up
to 100 m long.
Note: If the rain sensor has been activated, ie
has closed the window due to rain, it will take
at least 2 minutes before the comfort ventila-
tion can be activated again.
When connecting, lead cable through the rub-
ber membrane and fasten with cable tie.

acoustic alarm from control unit and connected
break-glass points.
(Factory setting).
Remove thin foil before setting the switches, if
necessary (1-6).
No external fire alarm is connected to FACU
terminal (FACU = Fire Alarm Control Unit).
(Factory setting).
If an alarm is activated via a smoke detector, the
window opens fully.
(Factory setting).
Cable errors are indicated by the red light-emit-
ting diode and an acoustic alarm from control unit
and connected break-glass points, and windows
open.
An external fire alarm is connected to FACU ter-
minal and the cable connection is monitored.
If an alarm is activated via a smoke detector, all
windows that are open (in comfort ventilation
position) close.
Note: If an alarm is activated via a break-glass
point, all windows open.

button. All windows connected to the control system
open. The red light-emitting diode over the red button in
the control unit is on and an acoustic alarm sounds. All
