For diverse applications

Pressure relief dampers Type FK2-DV for use in gaseous fire suppression systems, with 6 bar pneumatic actuator (no thermal release)

Initialize order code

General information

Application

The construction of the FK2-DV pressure relief damper is based on the FK2-EU fire damper. This damper is not a fire damper with thermal release mechanism, but a pressure relief damper for use in gaseous fire suppression systems (used primarily for server rooms and other IT rooms).

Special features

Pressure relief dampers do not require a building certificate, and they have no rating plate or CE marking
Approval of this pressure relief damper has to be covered by the approval of the gaseous fire suppression system; in other words, whoever builds or designs the gaseous fire suppression system has to make sure that the required pressure relief damper is included in the design and in the approval procedure
To ensure that the required fire resistance is achieved, the pressure relief damper has to be installed in compliance with the installation and operating manual for the FK2-EU fire damper
2 inspection accesses with bayonet fixing for single hand operation
Meets the hygiene requirements of VDI 6022-1, VDI 3803-1, DIN 1946-4, EN 3779, of Ö-Norm H 6020 and H 6021, and of SWKI
Corrosion protection according to EN 15650 in connection with EN 60068-2-52
Closed blade air leakage to EN 1751, class 2
Casing air leakage to EN 1751, class C; (B + H) ≤ 700, class B
Low differential pressure and sound power level
Any airflow direction

Classification

There is no building certificate for the pressure relief damper. If the installation is carried out according to the FK2-EU installation and operating manual, the stated fire resistance class applies to the closed pressure relief damper.

Supply package

Attachments and accessories that are factory mounted and supplied together with these pressure relief dampers have already been 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 involved in 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

General

Regular care and maintenance ensure operational readiness, functional reliability and long service life of the pressure relief dampers. The system owner is responsible for the maintenance of the dampers. The system owner is responsible for creating a maintenance plan, for defining the maintenance goals, and for the functional reliability of the equipment.

Functional test

The functional reliability of the pressure relief damper should be tested at least every six months; this has to be arranged by the system owner. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later. The functional test should be done with compressed air (6 bar), not with fire suppression gas.

Maintenance

The pressure relief damper and the pneumatic actuator are not subject to wear and hence maintenance-free, but the damper should still be cleaned if necessary.

Cleaning

Pressure relief dampers may be cleaned with a dry or damp cloth. Sticky dirt or contamination may be removed with a commercial, non-aggressive cleaning agent. Do not use abrasive cleaners or tools (e.g. brushes).

Inspection

Pressure relief dampers should be inspected before commissioning. This should be followed by regular functional tests; the tests should be arranged by the system owner and should be documented. If the requirements are not fully met, suitable remedial action must be taken.

Repair

For safety reasons, repair work must only be carried out by expert qualified personnel or the manufacturer. Only original replacement parts are to be used. A functional test is required after any repair.

For more information on maintenance see the FK2-EU installation and operating manual.

Technical information

Functional description Nominal sizes

The construction of the FK2-DV pressure relief damper is based on the FK2-EU fire damper.

The pressure relief damper is fitted with a single acting pneumatic actuator without thermal release mechanism. The damper is normally closed. If fire suppression is required, first the suppression gas pressure is reduced to 6 bar with a pressure regulator, then the gas is applied to the pneumatic actuator. The damper opens so that when the fire suppression gas is released, the excess air can escape. Two limit switches (supply package) can be used for indicating end positions OPEN and CLOSED.

Nominal sizes	200 × 100 – 1500 × 800 mm ³
Casing lengths	305 and 500 mm
Volume flow rate range	Up to 12000 l/s or 43200 m³/h
Differential pressure range	Up to 2000 Pa
Temperature range ²	-20 – 50 °C
Upstream velocity ¹	≤ 10 m/s

¹ * Applies to uniform upstream and downstream conditions for the pressure relief dampers.
² Condensation and the intake of humid air have to be avoided as otherwise operation will be impaired or not possible.
³ Damper blade with lip seal for sizes 1 and 2, damper blade with travel stop seal for size 3.

For sizes see the functional description.

Specification text

Pressure relief damper for use in gaseous fire suppression systems, construction based on the construction of FK2-EU fire dampers, square or rectangular, with two large inspection access panels that can be opened without a tool.

Pressure relief damper for installation in fire-resistant walls or ceilings, to prevent the penetration of heat, flames and smoke for up to 240 minutes.

Ready-for-operation unit, which contains a fire-resistant damper blade and a 1.2 bar pneumatic actuator (pressure off to close), without a thermal release mechanism and without building certificate. If the installation is carried out according to the FK2-EU installation and operating manual, the stated fire resistance class applies to the closed pressure relief damper.

Suitable for:

Mortar-based installation

In solid walls with installation kit EW and installation subframe
With fire-rated gypsum board or plasterboard in lightweight partition walls with metal support structure
With mineral wool in lightweight partition wall with metal support structure, timber stud walls, half-timbered constructions and solid wood walls
In shaft walls with metal support structure or steel support structure as well as in shaft walls without metal support structure
In solid wood ceilings and wooden beam ceilings
On the face of and remote from solid walls and ceiling slabs, with an installation kit
Remote from lightweight partition walls (wall penetration)

Fire batt installation

In solid walls and ceiling slabs
In lightweight partition walls, compartment walls, safety partition walls and radiation protection walls with metal support structure or steel support structure
