Latest edition 2018-04

In addition to DIN VDE 0833-1 and -2, the DIN standard DIN 14675 describes the professional construction and operation of a fire alarm system that triggers a direct alert to the fire brigade . It is valid in Germany and describes standardized fire service peripherals. The Fire Brigade Standards Committee (FNFW) NA 031 is responsible for creating the standard. This is why DIN 14675 is also known colloquially as the fire service standard .

However, DIN 14676 is not to be used in connection with fire alarm systems. This describes smoke alarm devices that can be used in apartments in accordance with building law requirements.


Since November 1, 2003, fire alarm systems with connection to the fire brigade should only be planned, configured, installed, commissioned, approved or regularly maintained by certified specialist companies. In addition to specialist planners in engineering and planning offices, specialist installers who set up the system can also be certified.

In order to receive certification according to DIN 14675, prior certification according to DIN EN ISO 9001 for quality management is required. Exception: For the execution of the planning phase according to 6.1, the submission of a quality management manual is sufficient as evidence of suitable quality management.


DIN 14675 differentiates between the task areas for setting up and operating a fire alarm system in phases. The specialist company for fire alarm systems (engineering office / specialist planner or specialist installer) - who want to be certified in accordance with DIN 14675 - must decide after which phases a certification is sought.

Phase 1 2 Phase name
06.1 planning
06.2 Project planning
07th Assembly
08th Commissioning
09 Decrease
11 maintenance
1 The numbering of the phases relates to the sections of the standard.
2 Certification according to phases 5, 10 and 12 not possible or necessary.

Specialist installers generally strive for certification for all phases; as a specialist planner, only certification according to phases 6.1 and 6.2 makes sense. In order to be able to offer manufacturer-neutral planning as a specialist planner (creation of the service description) as well as construction supervision and planning in existing buildings (e.g. in the case of expansion or conversion) as non-manufacturer-neutral planning, certification according to DIN 14675 according to phases 6.1 and 6.2 is mandatory required.

Scope of protection according to DIN

DIN 14675 divides fire alarm systems into four categories, according to which the surveillance can be designed or planned.

category Scope of surveillance
1 Full protection
2 Partial protection
3 Protection of escape routes
4th Facility protection

Technical connection conditions for fire alarm systems

The technical connection conditions for fire alarm systems (TAB) are published by the municipalities or under the direction of the local fire brigade. They define the individually specified technical connection conditions that are absolutely necessary in order to plan, install and maintain a fire alarm system in accordance with DIN 14675 so that it can be connected to the fire brigade. The fire alarm system is only accepted by the fire brigade if the respective technical connection conditions are met.

Since the revision of DIN 14675 in November 2003, many TABs have been updated in the meantime. Most of the newly written TABs now require the planners and installers of a fire alarm system to be certified in accordance with DIN 14675.

Main responsible person for fire alarm systems according to DIN 14675

The standard describes the specialist for fire alarm systems as the "person responsible" and requires training to become a person responsible for fire alarm systems according to DIN 14675. In every company certified according to DIN 14675, at least one specialist according to DIN 14675 must work. The main responsible specialist must pass a certified test according to DIN 14675. For phases 6.1 and 6.2, an additional project planning task must be completed in the test. The exam can only be taken at an accredited certification body in accordance with DIN 14675.

Development and updating of standards

DIN 14675 first appeared in August 1966. The three sub-standards were combined into one standard in 1979 and revised in 1984 and 2000.

DIN 14675 - November 2003

The standard published in December 2003 required the implementation of a quality management system for the first time and changes A1 to A3 to the pre-standard were incorporated.

DIN 14675 A1 - December 2006

Amendment A1 to the DIN 14675: 2003-11 standard has been available since December 2006. For the first time, the requirements for changing and expanding existing fire alarm systems are defined in a standard.

DIN 14675 A2 - June 2009

With the June 2009 edition, the new standard DIN 14675 A2 Fire alarm systems - construction and operation; Amendment A2 available. The following changes have been made to DIN 14675: 2003-11:

  1. Term and definition 3.1 "interrogating connection" is deleted because the term no longer occurs in the standard;
  2. Requirements in Table A.1 have been editorially adapted to the requirements of EN 50136-1-1;
  3. Requirements in table A.1 technically adapted to the requirements of EN 54-21;
  4. In Table A.1 the transmission routes have been supplemented with examples

DIN 14675 - April 2012

The standard DIN 14675: 2012-04, revised and supplemented in April 2012, represents the consolidated version of DIN 14675: 2003-11, DIN 14675 / A1: 2006-12, DIN 14675 / A2: 2009-06 and DIN 14675 / A3, which was published as a draft in June 2010. The standard was expanded to include the requirements for the competence of specialist companies for voice alarms according to EN 54-16, EN 54-24 and DIN VDE 0833-4 (VDE 0833-4). The existing certification of specialist companies for fire alarm systems (BMA) will be expanded to include the certification of specialist companies for voice alarm systems (SAA).

DIN 14675 supplement 1 - December 2014

The working group NA 031-02-01-02 AK "Planning, Maintenance, Assembly" of the working committee NA 031-02-01 AA "Fire detection and fire alarm systems" of the fire fighting standards committee has developed these application recommendations for DIN 14675: 2012-04. However, it does not contain any additional standardized specifications.

  1. Change in the accreditation standard for certification bodies (DIN 45011 replaced by DIN EN ISO / IEC 17065: 2013-01)
  2. Explanation of the term “factory test” with regard to point-type smoke detectors according to DIN EN 54-7
  3. Changes and extensions to existing BMA refer to Appendix S instead of Appendix R as originally
  4. The transmission paths between FBF and the BMZ must be monitored directly.
  5. Alerting via telecommunications systems basically replaces alarm systems that are not required according to H.3.1 and H.3.3.

DIN 14675 - April 2018

In 2018, the European requirements of DIN EN 16763 were integrated into DIN 14675 and thus replaces the previous version from April 2012 including the supplement from December 2014.

International counterparts

In Austria, the relevant standards are described in TRVB -123 00 and in TRVB-114-06.
