CR120 - Installation
Installation at a minimal distance from another damper or from an adjacent supporting construction
Principle
According to the European test standard EN 1366-2, a fire damper must be installed at a minimum distance of 75 mm from an adjacent supporting construction (wall/floor) and 200 mm from another damper, unless the solution was tested at a shorter distance. This range of Rf-t fire dampers has been successfully tested and can be installed in a vertical or horizontal supporting construction, at a distance below the minimum set by the standard.
For circular dampers, the minimal distance is set to 30 mm.

For circular dampers, the minimal distance is set to 30 mm.
Certified solution
For the Rf-t fire dampers, the solution consists of the following elements: A: Universal sealing for minimal distance; B: Sealing compliant with existing classifications (Declaration of Performance).
A. Sealing of the opening at the side with minimal distances between damper and wall/ceiling or another fire damper: rigid stone wool panels (150 kg/m³) are applied to a depth of min. 400 mm, of which 150 mm on the mechanism side of the wall. On the non-mechanism side of the wall, the stone wool panels must be at least flush with the wall.
The surface of this sealing is set between the axes (centres) of the dampers.
B. Sealing of the rest of the opening according to the existing classifications for the fire damper (Declaration of Performance).
This also applies to circular dampers that are mounted at a minimum distance from one another (30 to 200 mm) but at a distance greater than 75 mm from a wall/ceiling.
Detailed information for each wall/sealing combination can be found in the respective installation methods.

Restrictions
The orientation of the blade axis should be horizontal or oriented at a maximum of 45°.
A maximum of 3 circular dampers can be installed at a minimum distance from one another, both vertically and horizontally (with a maximum cluster of 4 dampers).
Note: when sealing the opening with panels of fire resistant stone wool, the maximum number of dampers also depends on the maximum “blank seal” allowed for the selected sealing material. Please refer to the manufacturer's instructions for this information.
Note: separate conditions apply for installation in flexible shaft wall and CLT wall. Detailed information can be found in the relevant installation methods.

A free space of maximum 25 mm is left between the threaded rods and the vertical walls of the stone wool casing “B”.
The opening around the duct is sealed with standard mortar.
The duct is covered over its entire length with stone wool plates “G”. To adhere to the duct, the plates are completely coated on one side with fire resitant coating and affixed to the duct with steel screws and washers “E”.
The damper casing is covered with stone wool plates “G” for 171 mm. A free space should be left around the mechanism to guarantee access.
An additional stone wool panel type “G”, coated with PROMASTOP-CC / HILTI CFS-S ACR, is applied in the opening between the damper casing and the stone wool panels.

Inspection of the damper via UL option or via the fusible link opening of the ONE mechanism
An inspection opening (only available when ordering the ‘UL’ option) allows the position and condition of the damper to be visually determined with an endoscope. For fire dampers equipped with the ONE mechanism, it is also possible to carry out this camera inspection through the opening of the fusible link.
Option UL:
Remove the air-tight plug from the damper.
Option UL:
Remove the air-tight plug from the damper.
Insert the camera of the endoscope (for example Inspecam Rf-t) through the opening and inspect the inside of the damper.
After inspection, replace the air-tight plug thoroughly on the damper opening. The position is crucial in order to maintain the air-tightness of the fire damper.
ONE mechanism:
Open the battery compartment.
Open the battery compartment.
Press the flexible button inside the battery compartment.
Pull the fusible link and the rubber cover simultaneously out of the mechanism.
Insert the camera of the endoscope (for example Inspecam Rf-t) through the opening and inspect the inside of the damper.
Slide the fusible link back into the mechanism until it clicks into place. Close the cover of the battery compartment with the ruber cover.

General remarks
- The installation must comply with the installation manual and the classification report.
- Axis orientation: see the declaration of performance.
- Avoid obstruction of adjoining ducts.
- Product installation: always with closed damper blade.
- Verify if the blade can move freely.
- Please observe safety distances with respect to other construction elements. The operating mechanism must also remain accessible: allow for a clearance of 200 mm around the housing.
- The air tightness class will be maintained if the damper is installed according to the installation manual.
- Rf-t fire dampers are always tested in standardised constructions according to EN 1366-2. The achieved results are valid for similar supporting constructions with a fire resistance, thickness and density equal or superior to the supporting construction used during the test.
- If the wall thickness exceeds the minimum thickness specified in our installation instructions, the following conditions apply to the sealing depth: - For flexible walls and sandwich panel system walls, the seal must always be applied over the full depth of the wall. - With rigid walls, rigid floors and plaster block walls, the minimum sealing depth as indicated in our installation instructions (often equal to the minimum wall thickness) is sufficient. Apply the seal at the height of the damper blade (from the wall limit indication).
- When installing a fire damper in a flexible metal stud wall, some installation methods do not require reinforcing profiles around the wall opening from a fire protection point of view (see below). Always follow the general instructions of the manufacturer of these wall systems when building this type of wall.
- The damper must remain accessible for inspection and maintenance.
- Schedule at least 2 visual checks each year.
