The following applies to Germany: If fire dampers with a purely mechanical shut-off element are to be used as an upstream shutter of an air transfer unit, the local building regulations must be observed. Usually the use of such upstream shutters of air transfer units is restricted to pressure differential systems.

Standards and guidelines
Supply package
If attachments and accessories are supplied from the factory with the fire dampers, they are already taken into account in the order code. Depending on the installation situation, supplementary materials for assembly and fixing may be needed to ensure proper installation, e.g. mortar, screws, mineral wool, etc. Such materials are not included in the supply package, unless they are expressly described as included in the supply package. The selection of additional attachments or accessories as well as the identification and provision of materials for assembly and fixing is the responsibility of those involved in the building project and must be done taking into account the required classification.

Specification text
Fire damper according to the European product standard EN 15650 in circular construction style. Tested for fire resistance properties according to EN 1366-2, with CE label. The fire damper manufacturer's declaration of performance (DoP) provides proof of the respective installation conditions, e.g., in walls or ceilings, along with the basic characteristics such as size, support structure, design and installation type and the respective classes of performance in accordance with the classification standard EN 13501-3. Ready-to-use units contain a release mechanism and an interchangeable, fire-resistant damper blade that can be arranged horizontally or vertically and in all intermediate positions (0 - 360°) depending on the use. Depending on application, classified from: EI 30 (ve, ho i ↔ o) S to EI 120 (ve, ho i ↔ o) S
Suitable for:
Mortar-based installation
Dry mortarless installation
Fire batt installation
In timber stud walls, half-timbered constructions, solid wood walls and CLT walls
Sizes from nominal size 315 mm – 800 mm. Optimised low-leakage casing, up to leakage class C to EN 1751 with low differential pressure and low sound power level. Fire damper casing made of galvanised sheet steel, optionally galvanised sheet steel with powder coating RAL 7001 or stainless steel 1.4301. Damper blade made of special insulation material, optionally with coating. Corrosion protection according to EN 15650 in connection with EN 60068-2-52. Hygienic requirements are fulfilled in accordance with VDI 6022-1, VDI 3803-1, DIN 1946-4, DIN EN 13779 as well as the Önorm H 6020 and H 6021 and the SWKI. Casing in spigot design (length 550 mm) or flange design (length 495 mm) for connection to ducts made of non-combustible or combustible building materials. Thermal release for 72°C or 95°C (warm air ventilation systems) with a fusible link or thermoelectrically with a spring return actuator, push button and indicator light (LED). Constructions with a brushless actuator for opening and closing the fire damper, also when the ventilation system is running and independent of the nominal size, are particularly suitable for functional checks and for shutting off sections of the duct system. Retrofit of spring return actuators without modification of the rod is possible from the outside. Explosion-proof constructions for zones 1, 2, 21 and 22 available with limit switch or spring return actuator. In the version with thermal insulation made of 32 mm synthetic cellular rubber, fire rating class: B-s2-d0, spring return actuator and perimeter mortar infill, suitable for reducing condensation in the case of outdoor air intake (ODA Outdoor air).

If the damper is to be used as an air transfer unit in Germany please note: If a fire damper with only a mechanical shut-off element is to be used as an air transfer damper (FD), the local building regulations apply. Such applications may require a building inspectorate licence. This must be checked and applied for by the client. Such air transfer dampers (FD) are usually used in pressure differential systems only.
