Our products are
QS approved
All products of our product range are subject
to a continual quality control process during
production. A standardised pre-delivery check
is performed prior to shipment. Development,
production, shipping and our well-known
competent “After Sales Service” are subject to
the stringent requirements of DIN EN ISO
9001.
BTR Group has been certified according to
DIN EN ISO 9001 for years. Compliance with
the requirements of the standard are regularly
verified by VdS Schadenverhütung (A company
of the German Insurance Association GDV).
Products requiring CE conformity in accordance
with applicable regulations are identified
with the CE symbol. Declarations of conformity
are available for all affected products
and can be obtained upon request.
The BTR Group
The BTR Group has been active in the problem
area of smoke vent systems for many decades.
Development, production, supply and service,
especially of electric motor driven smoke vent
systems, are the main focus of our activities.
We are also well known for the development of
special solutions in the area of smoke extraction,
regardless whether the demand concerns
electrical, pyrotechnical or pneumatic actuation.
An important aspect of our field of activity is
training and education of our staff, not only
concerning products, but also in regard to
service and commissioning.
Our partner organisations in Germany and
abroad are at your service with advice and
support, in order to meet any fire protection
requirement in the interest of the customer as
well as safety.
Our experienced engineers are available to
solve your particular problems.

Danger by flue gases/consequential damages
Fire casualties are smoke casualties. Smoke
from a fire consists of a mix of complete and
incomplete combustion. Depending on the nature
of the source of the fire, the smoke is
mixed with solid particles and soot particles.
There are two possible causes for death by
asphyxiation:
1. The smoke of the fire contains lethal toxic
components. These may, depending on
their concentration and type, result in
death within a very short time.
2. The smoke of the fire contains so-called
“corrosive components”. Inhalation of
these substances causes causticization
(burning) of the lungs and respiratory tract.
In most cases, the interaction of both causes
is the reason for smoke poisoning and serious
internal injuries of fire victims. The consequences
are permanent injuries or death of fire
victims.
Propagation of smoke without and with a smoke
vent system
Fire victims as a consequence of direct contact
with fire are relatively rare. However, this
type of risk increases, if there is an uncontrolled
blazing fire due to the absence of
smoke and heat extraction systems.
Flue gas volumes created by fires
Almost any type of combustion results in the
creation of more or less toxic flue gases. The
diagram at right shows the enormous volumes
of flue gases that may be created within a very
short time during the combustion of various
building materials. Particularly building materials
that are used for heat or sound insulation
are giving off very high volumes of flue gas
during combustion.
Rooms or buildings without a smoke vent system
can be completely filled with smoke within
minutes.
One example: A staircase with a floor space of
16 m 2 and a height of 15 metres is completely
filled with smoke and conflagration gases
more than 100 times with the combustion of
just 10 kg of foam rubber.
Fumes, conflagration gases and smoke development
with combustion of 10 kg of material.

Smoke extraction systems designed by BTR
provide smoke-free escape routes and secure
access for the fire brigade, resulting in the
preservation of life and property as well as limiting
fire damage.

Smoke extraction and ventilation systems
with electric motor driven actuation
Utilisation:
Smoke vent systems in staircases, meeting
halls and other buildings, in accordance with
German building regulation:
Advantages/features:
• High level of operational security due to
certified products.
• Daily ventilation with any desired flap
opening position possible.
• Functional security in case of 230 V mains
power failure through built-in emergency
batteries.
• Electrical integration with other systems
possible.
• Attractively designed actuators and drives.
• Connection to nearly all types of flaps,
windows and skylights possible.
• Low maintenance, hardly any
consumables in the course of maintenance
or wilful actuation.

Smoke vent buttons
Smoke vent buttons are pressed in an emergency
to manually trigger an electric motor
driven smoke vent system. In accordance with
the locally applicable building regulation, one
or multiple smoke vent buttons are required.
They are available in the approved colours orange,
grey, blue and yellow. A hidden “Reset”
button can be used to reset the smoke vent
system after it has been triggered in an emergency.
Control panels
The smoke vent system control panel receives
external signals and commands, processes
these and controls the 24 V motorised actuators
of the smoke vent system. The control
panel houses the power supply, control system,
terminal strips, battery charging devices
and two maintenance-free emergency power
batteries. The smoke vent system control panels
are offered in compact design units for
standard systems, for example, in staircases,
and in modular design for custom-tailored applications,
for example, for glass facades in
shopping centres.
Motors
The attractively styled 24 V motorised actuators
are suitable for all common types of
flaps and wings. The range of products includes
motors with a stroke of up to 1000 mm
and lifting power of up to 1000 N. The motor
housings can be painted in any available RAL
colour. A wide range of brackets is also available.

Chain drives
24 V chain drives are used to satisfy the highest
demands on visual appearance, while at
the same time assuring compliance with building
regulations. These attractively styled motors
come with a stroke of up to 600 mm and
lifting power of up to 400 N. They are predominantly
used with sash and top-hung sash windows.
Automatic wind-rain
actuation
In connection with the operating mode for
“daily ventilation”, it is possible to automatically
close the smoke vent system by means
of an automatic wind-rain actuator. Naturally,
an alarm case will continue to have priority.
The point of closure is adjustable.

Smoke vent systems
protect life and property
Smoke vent drives on window sashes provide not just security,
but are also attractively styled and come with the added “daily ventilation” function.
