Damper blade:

Special insulation material
Special insulation material with impregnation
Replaceable damper blade (from NS 180 mm)

Other components:

Damper blade shaft made of galvanised steel or stainless steel

Elastomer seals

The design variants made of stainless steel or with powder-coated casings meet increased requirements for corrosion protection. Detailed resistance lists upon request.

Supply package

If attachments and accessories are factory-mounted on the fire dampers, they are already included in the order code. Depending on the installation situation, additional materials such as mortar, screws or mineral wool may be required for correct installation. Such materials are not usually included in the supply package (unless stated otherwise). Attachments and accessories have to be selected by people in charge of the building project. These people also have to select and provide any additionally required installation or fixing materials and make sure that the required classifications are met.

Maintenance

The functional reliability of the fire damper must be tested at least every six months; this has to be arranged by the owner of the ventilation system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later.
A functional test involves closing the damper blade and opening it again; with a spring return actuator this can be done via remote control
Fire dampers must be included in the regular cleaning schedule for the ventilation system.
For details on functional tests, maintenance and inspection refer to the installation and operating manual

** Data apply to uniform upstream and downstream conditions of the fire dampers

Correct use

The fire damper is used as an automatic shut-off device to prevent fire and smoke from spreading through ducting.
The fire damper is suitable for supply and extract air in HVAC systems.
The fire damper may be used in areas with potentially explosive atmospheres if suitable special accessories are used with it and if the product bears the CE conformity marking according to Directive 2014/34/EU. Fire dampers for use in areas with potentially explosive atmospheres are marked for the zones for which they have been approved.
Operation of fire dampers is allowed only in compliance with installation regulations and the technical data in the installation and operating manual.
Modifying the fire damper or using replacement parts that have not been approved by TROX is not permitted.

Incorrect use:

without specially approved attachments in areas with potentially explosive atmospheres
as a smoke control damper
outdoors without sufficient protection against the effects of weather
in atmospheres where chemical reactions, whether planned or unplanned, may cause damage to the fire damper or lead to corrosion

For installation in Germany please note:

Do not use it in extract air systems in commercial kitchens
Do not use it as an air transfer damper
Do not use it with a combined penetration seal
Single installation in a sandwich panel wall is considered correct use. Do not combine it with cable penetrations
Air transfer units may require a building inspectorate licence. This has to be determined and applied for on a case to case basis (by others).
Flame-resistant building materials that form no dripping droplets (elastomer foams) have to be at least of fire rating class C - s2, d0 according to the German MVV TB (2019/1) guideline. The current national building regulations apply.

Construction with fusible link

In the event of a fire, fire dampers shut automatically to prevent the propagation of fire and smoke through ductwork to adjacent designated fire compartments. In the event of a fire, the damper is triggered at 72 °C or at 95 °C (use in warm air ventilation systems) by a fusible link. The release mechanism is accessible and can be tested from the outside

One or two limit switches (optional attachment) can be used to indicate the damper blade position.

Attachment – Duct smoke detectors

General

To prevent smoke from spreading in buildings, it is extremely important that the smoke is detected at an early stage.
Duct smoke detectors that operate on the principle of light scattering detect the smoke regardless of its temperature so that the fire dampers can be closed before the release temperature of 72 °C is reached
If the air contains suspended particles, as is the case with smoke, beams of light are deflected off these. A sensor (photodiode), which does not receive light in clear air, is illuminated by the scattered light.
The fire damper or smoke protection damper blade is released when the brightness of the scattered light exceeds a certain threshole

Duct smoke detector for fire dampers and smoke protection dampers
General building inspectorate licence Z-78.6-125
For airflow velocities from 1 – 20 m/s
Independent of the airflow direction
Supply voltage 230 V AC, 50/60 Hz or 24 V DC with voltage monitoring module (VWM) (upon request)
Volt-free signal and alarm relays
Integral signal lamps
Contamination level indicator
Automatic adjustment of alarm threshold
Long service life
Temperature range 0 – 60 °C

The duct smoke detector must be ordered as a separate attachment and must be installed by others in the duct.

When used as an air transfer damper, the duct smoke detector is mounted on the FKRS-EU and supplied pre-wired.

MONTAGEVIDEO

EINFACHE MONTAGE: WEICHSCHOTTEINBAU FÜR RUNDE TROX-BRANDSCHUTZKLAPPEN

Während in der Vergangenheit die Öffnungen für den Einbau einer Brandschutzklappe in eine massive Wand oder Decke exakt und nur mit geringen Toleranzen geplant und ausgeführt wurden, können die Weichschott-Lösungen sehr viel flexibler gehandhabt werden. So wird die Montage in vorhandene Öffnungen möglich, die umlaufend um bis zu 400 mm größer sein können als die Gehäuseabmessung. Exakte Planungen der Einbauöffnungen sind damit nicht mehr zwingend erforderlich
