Fire protection systems for ventilation systems

Fire protection systems mainly consist of straight air duct sections, fittings, seals, connectors and fasteners, classified or unclassified wraps and shut-off devices for fire and smoke etc. They may only be used to prevent the spread of fire from storey to storey for exhaust ventilation systems in accordance with DIN 18017-3 or accordingly for systems based on DIN 18017-3 in which supply air is ducted.

The components of the fire protection system combined prevent the spread of fire and smoke to other storeys for the verified duration.

Regulatory framework

DIBt grants national technical approvals (abZ)/general construction technique permits (aBG) for fire protection systems for use in exhaust ventilation systems in accordance with DIN 18017-3 or accordingly for systems based on DIN 18017-3 in which supply air is ducted (see e.g., M-LüAR, Section 7.2).

Please also refer to the relevant provisions of the federal states following MVV TB 2020/1, Sections A 2.2.1.16 and A 2.2.1.11 (M-LüAR).

National procedure

To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.

For a first assessment, please send us the following information:

  • Description of the construction product and its intended field of use
    • e.g. material, configuration, number of sizes, variants, dimensions
    • e.g. use in walls, ceilings, interior construction, building services
  • Description of the construction technique and its field of application
    • e.g. design of walls, ceilings, elements, etc., and interaction of components
    • e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
  • Information regarding impact on regulatory concerns
    • in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
  • Explanation of need for an abZ/aBG
  • Contact details
    • preferably email address and/or telephone number, as well as name, organisation/company, and postal address

We will then contact you to clarify the next steps.
