Warning
By attaching an electric operating drive to
a movable element of a window and con-
necting it to a power supply a so-called
“power-operated window” is created which,
according to the Machinery Directive
2006 / 42 / EG, represents a machine. The
control device is designated for driving such
a window. Where it seems reasonable, these
installation instructions point out sensibly
predictable hazards and risks resulting from a
power operated window.
By connecting the window drives with
a control device and their operation the
constructor of the complete system beco-
mes the manufacturer of the power-ope-
rated window! If necessary, he is obliga-
ted to perform a risk assessment of the
complete system in accordance with the
Machinery Directive 2006/42/EG when
the utilization or operation of the control
device or the connected window drives
deviate from their intended use!
Attention must be paid to possible
hazards when used with tilting or
rotating windows, whose secondary
closing edges are located at less than
2,5 m installation height above the oor,
under consideration of the Control Unit
and usage!

intended use
Area of application / Scope of application
This control device is intended for power-feeding and con-
trolling of electromotive operated windows in facade or
roof areas. The prime task of this product, in combina-
tion with the electromotive window, is to evacuate hot
smoke and combustion gases in case of re to save
human lives and protect material assets. Furthermore, the
electromotive operated window ensures fresh air supply
for the natural ventilation of the building.
Intended use
The control device is intended for stationary installation and
electrical connection as part of a building.
In accordance with the attached Declaration of Con-
formity the control device, in combination with electro-
motive drives from Btr, is released for its proper use at a
power-operated window for the following use:
• Application for natural ventilation

with an installation height of the drive and
the bottom side of casement of at least 2,5 m above
the oor, or

with an opening width at the HSK of the driven
part of < 200 mm by a simultaneous speed of
< 15 mm/s at the HSK in closing direction.
• Application as NRWA (natural smoke and heat
exhaust ventilator(s) in accordance with EN12101-2
without dual purpose for ventilation.
We as manufacturers are well aware of our duties and
responsibilities regarding the development, manufactu-
ring and placing of safe window drives on the market and
consistently implement them. Ultimately, however, we have
no direct inuence on the usage of our drives. Therefore,
as a precaution, we point out the following:
• The constructor or his agent (architect, specialist
planner) are obligated by law to evaluate the
hazards to persons, originating from the usage,
installation position, opening parameters as well as
the planned type of installation of the power
operated window and the external Control Unit,
already in the planning phase and to establish
necessary protective measures.
• The constructor / manufacturer of the machine
“power-operated window” must implement the
planned protective measures at the installation site
or, if not yet established, determine them by theire
own responsibility and detect or minimize possible
remaining risks.

necessary under the following conditions:
• the installation height of the drive or of the „HSK / main
closing edge“ (parallel to hinge) < 2,5 m above the oor
and one of the following conditions:
• the opening width at the HSK is > 200 mm, or
• the closing speed at the HSK is > 15 mm/s, or
• the opening speed at the HSK is > 50 mm/s, or
• the closing force at the HSK is > 150 N
The following ow chart can be applied, which also includes
the protective measures in accordance with EN 60335-2-
103/2016-05.

safety instruCtions
Crush and shear points
To avoid injuries, crushing and shear points between
casement and frame must be secured against entrapment
up to an installation height of 2,5 meters above the
oor with appropriate measures. This can be achieved e.g.
by using contact-based or contactless protective devices
against entrapment, which stop the motion through contact
or through interruption by a person. A warning symbol at
the opening element must indicate this clearly.
Routing cables and electrical connection
Routing or installing electrical lines and connections may
be performed only by approved specialist companies. Never
operate drives, Control Units, operating elements and sen-
sors at operating voltages and connections contrary to the
specications of the manufacturer.

explicitly described in these instructions
require the express written consent of
btr. Utilization of applications and com-
ponents not expressly authorized by btr
are considered as unintended use even
if their perfect functioning is proven at
commissioning (e.g. approval under buil-
ding law).
note
Basic functions of RWA (smoke and heat exhaust sys-
tem) control devices:
• Control of electromotive window drives for smoke
and heat exhaust in case of re and for “natural
ventilation”.
• Evaluation of trigger signals of manual and automatic
smoke detectors as well as of re alarm systems.
• Emergency power supply provided by accumulators
for maintaining safety functions if power
supply is interrupted in case of re.
• Monitoring the power supply of all important con-
nections for malfunctions.

instAllAtion step 6:
enabling oPeration / ComPleting installation / troublshooting
instAllAtion step 6: enabling operation/completing installation
For safety reasons the Control Unit is supplied with
„deadman“ pre-setting for ventilation. You require the
software for switching over to „latching“. It is abso-
lutely necessary to ensure that all safety-relevant re-
quirements for the „latching“ mode are guaranteed
according to the information provided by the manu-
facturers of the connected opening components.
RWA systems require a logbook, in which all important master data have
to be entered prior to operation enable and all operational events during
the period in operation.The logbook is part of the system documents and
must be stored and available to authorized staff at all times.
We advise to perform an insulation measurement of the cable network
before enabling operation of the plant and to keep a written record of
this test.
Provided that the factory default conguration has been changed using
the system software, all alterations have to be taken into
account in the operating manual. It might be required to prepare an ope-
rating manual for non-specialist users that is easy to follow and well
understandable.
In case of re the system saves lives. Therefore
immediately remedy or have any fault or mal-
function remedied by specialists!
Depending on the storage period the back-up accumu-
lators require some time to be fully charged. Therefore,
bridging time (see chapter „Data sheet“) for the power
failure might not be ensured after connecting the
back-up accumulators and the back-up accumulators
rst need some charging time in mains operation
to reach the maximum charge status (min. 8 hours).
The Control Unit must not be enabled for operation
unless all system components work properly. This also
applies to system components that do not come under
our producer responsibility or whose installation had not
been commissioned but are still components of
the RWA system. Upon completion of the installation,
all functions of the Control Unit must be checked
for correct functionality with utmost care. Even
if there is no fault indication this does not mean that all
components function faultlessly.
!
Warning
Before the installer is allowed to enable the operation of the Control Unit,
the complete performance range of the system must be checked with
utmost care. The chapter „Troublshooting anD repair“ provides support
for the localisation of possible faults and malfunctions.
On the last page you nd an overview of all external connections where
the current assignments can be entered.
Modications of the system using the system software should take place
after the complete installation of the Control Unit and all components
being connected. When required, the system conguration and status
can be saved or printed using the system software. In the case of faults
or malfunctions of system components it might also be necessary to
thoroughly check the system conguration (computer to be connected
using system software).

Follow the instructions in the chapter „safety in-
struCtions“.

Before changing the operating mode check and pay
attention to danger zones at the window!

troublshooting and repair
All functions and system components that are important for the
RWA operation are constantly monitored for faults. A fault indication
signals the type of fault and, respectively, possible errors when connecting
system components (such as back-up accumulators, detectors, drives)
during commissioning of the Control Unit.
The overview below details some of the possible faults and problem
cases and their causes. „Indicator B“ means the green operating indi-
cator which does not light up in case of a fault. The yellow “Indicator S”
signals the type of fault.
You nd a list of all indicators in chapter „leD´sanD Dip switChes“ - on
the previous page.
