Standards and guidelines

Construction Products Regulation

EN 15650 Ventilation for buildings – Fire dampers

EN 1366-2 Fire resistance tests for service installations – Fire dampers

EN 13501 Fire classification of construction products and building elements

EN 1751 Ventilation for buildings – Air terminal devices

Supply package

If attachments and accessories are factory set with the fire dampers, they are already included in the order code. Installation situations may require supplementary materials for assembly and fixing, such as mortar, screws, mineral wool, etc., to ensure correct installation. Such materials are not included in the scope of delivery, unless they are expressly described as part of the delivery. The selection of supplementary attachments or accessories as well as the determination and provision of materials for assembly and fixing is the responsibility of the parties involved in the construction and must be carried out taking into account the desired classification.

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. If 2 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

Accessories 2 – Flexible connectors

Application

Ducting must be installed in such a way that it does not impose any significant loads on the fire damper in the event of a fire. Be sure to comply with the relevant national guidelines and regulations
As ducts may expand and walls may become deformed in the event of a fire, we recommend using flexible connectors for installation in lightweight partition walls, shaft walls and lightweight compartment walls, as well as fire batt installation.
Flexible connectors should be installed in such a way that both ends can absorb both tension and compression
Flexible ducts can be used as an alternative
For heights > 400 mm, extension pieces are required due to construction
The fixing holes in the flexible connectors and extension pieces match those in the fire damper flanges
Flexible connectors are also available separately

Attachment – Duct smoke detectors

Application

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 threshold

Attachment	Order code
Duct smoke detector	RM-O-3-D
Duct smoke detector	RM-O-VS-D

Duct smoke detectors are attachments and to be ordered separately.

RM-O-3-D can also be supplied assembled and wired for FK2-EU with standard application.
