fire brigade

Connection to the fire brigade and connection conditions in NRW

If your fire alarm system is connected to the fire brigade, the Technische Anschlussbedingungen (TAB, technical connection conditions) of your Brandschutzdienststelle (fire protection authority) also apply. Here you will find what applies to a detector replacement or a significant modification – and the connection conditions of all districts and independent cities in NRW.

Fire brigade and connection

New fire brigade connection or extended acceptance inspection after a significant modification?

In NRW there is no uniform state-wide rule for this. Inspection by approved inspection experts is governed by the Prüfverordnung NRW (PrüfVO NRW) – whereas acceptance by the fire brigade and connection to the control centre are regulated by each Brandschutzdienststelle (fire protection authority) in its Technische Anschlussbedingungen (TAB, technical connection conditions). The basic pattern, however, is the same everywhere:

Significant modification

  1. Before: Coordinate the modification with the fire protection authority – depending on the municipality, this may even mean a new planning meeting.
  2. Afterwards: Inspection by approved inspection experts before recommissioning (PrüfVO NRW, § 2).
  3. Fire brigade: depending on the TAB, a new acceptance inspection by the fire brigade – usually only once a defect-free inspection report is available.
  4. Documents: Update and submit the FAS concept, fire brigade plans and fire brigade route cards.

A new connection in the sense of a new connection application is not explicitly required by the TABs we evaluated. As a rule, it only becomes necessary if something changes on the transmission equipment itself.

Like-for-like detector replacement

  • no expert inspection, no fire brigade acceptance, no new connection
  • Coordinate any disconnections during the replacement with the control centre in advance
  • Document the replacement in the logbook; detector designations and route cards remain valid

For minor modifications in Cologne, notifying the fire brigade is sufficient; it then decides whether a planning meeting or an acceptance inspection is required.

How fire protection authorities in our region handle it

Fire protection authorityBefore the modificationAfter the modificationNew connection?
Kreis Viersen
(incl. Schwalmtal; all municipalities except the city of Viersen)
Coordinate every subsequent modification with the fire protection authority (item 1.2); coordinate planning documents with the fire protection authority and the expert before installation begins (item 10.2); report modifications (item 16)Expert inspection before recommissioning (items 11.1, 12.1); defect-free inspection report before the connection acceptance by the fire protection authority (item 11.2)Not explicitly regulated for modifications – clarify with the fire protection authority; otherwise connection application 8 weeks in advance (item 2)
Stadt ViersenCoordinate the overall concept and every subsequent modification with the fire protection authority (item 1.2); coordinate planning documents with the fire protection authority and the expert before installation begins (item 10.2); report structural and operational changes, update plans (item 16)Expert inspection under PrüfVO NRW after significant modifications before recommissioning (item 11.1); expert’s certificate before the connection acceptance by the fire protection authority (item 11.2)Not explicitly regulated for modifications – clarify with the fire protection authority; otherwise connection application to the concession holder at least 8 weeks in advance (item 2)
Kreis Heinsberg
(incl. Wegberg, Heinsberg)
Coordinate the overall concept and modifications to existing systems with the fire protection authority before execution (item 1.3); report modifications such as new detector zones or replacement of the FACP to the coordination office without delay (item 11.3)In the case of significant modifications or extensions, the entire FAS must comply with the current state of the art; minor modifications do not affect grandfathering (item 5.2); the expert report must be presented at the acceptance inspection (item 8)Not explicitly regulated for modifications – clarify with the fire protection authority; otherwise agree the connection date at least 4 weeks in advance (item 8)
Stadt DüsseldorfCoordinate the overall concept and every subsequent modification with department 37/52 before execution; update the fire detection and alarm concept with every modification, extension or replacement and submit it for approval (section “Allgemeine Anforderungen”, Annex J)Report modifications in writing to the building control authority and the fire brigade (section “Bauliche und betriebliche Änderungen”); certificate from a state-recognised expert under PrüfVO NRW before the connection acceptance, inspection reports at least 5 working days in advance (Annex K)Connection acceptance with the concession holder in the case of changes to the transmission equipment; in the case of extension or replacement, retrofit a fire brigade indicator panel according to DIN 14662 if none is present
Stadt EssenCoordinate every subsequent modification with the fire detection technology department before execution (items 1.2, 5.1); submit the current fire detection and alarm concept; modifications not agreed in advance are deemed an unapproved condition (item 5.1)Expert inspection under PrüfVO NRW for significant modifications (items 3.3, 5.1); follow-up acceptance by the fire brigade (item 4.1), appointment approx. 2 weeks in advance (item 4.2); the TAB, DIN and VDE standards valid on the day of acceptance are decisive (item 5.1)No – follow-up acceptance instead of a new application (item 4.1); application only for a new connection or change of operator, at least 8 weeks in advance (item 1.4)
Stadt KölnNew planning meeting mandatory before work begins (point 11)New acceptance inspection by the fire brigade required (points 11, 9); the fire brigade may require the entire FAS to be brought into line with the current connection conditionsNot explicitly regulated; new connection only on application (8 weeks’ lead time, point 3)
Stadt KrefeldCoordinate planning with the fire brigade (item 1.2); report technical changes without delay using the “Anlage 17” application form (item 7.3); extension only if the VdS system approval is still valid (item 2.8.1.3)Fire brigade acceptance of the modified system parts if they can trigger the transmission equipment (item 8.1.1.2), application 4 weeks in advance (item 8.1.2.1); defect-free expert inspection report beforehand (item 8.3.4)No – modification application and fire brigade acceptance; for a “minor modification” the fire brigade may waive this (item 8.1.1.2)
Stadt MönchengladbachCoordinate every subsequent modification with the Vorbeugende Gefahrenabwehr (fire prevention) department before execution (item 1.3)Report structural and operational changes in writing to the building regulation authority and the fire brigade, update fire brigade plans and detector zone plans (item 11.4); connection acceptance only with the acceptance report of the expert under PrüfVO NRW (item 11.1)Not explicitly regulated for modifications – clarify with the fire brigade
Stadt NeussCoordinate significant modifications with the fire brigade in advance, already in the planning phase (item 7.6)New acceptance inspection depending on scope (item 7.6); acceptance report of the approved inspection expert under PrüfVO NRW (item 7.1)Not explicitly regulated; update fire brigade plans and route cards beforehand (item 6.1)

Anyone who carries out a significant modification without involving the fire protection authority risks consequences: the Cologne fire brigade, for example, can then inform the building control authority. The current TAB of the fire protection authority responsible for your property is always decisive – consult it before every significant modification.

Connection conditions of all districts, cities and independent cities in NRW

In addition to the districts and independent cities, many towns belonging to a district have their own fire protection authority with their own connection conditions. Where published online, they are listed indented (↳) under their district. The authority in whose area your property is located is always decisive.

Different names, same content: In the past, these sets of rules were mostly called Technische Anschaltbedingungen (TAB), today predominantly Anschlussbedingungen. Many fire protection authorities have not yet renamed their documents – depending on the location, they are called “Technische Anschaltbedingungen”, “Technische Anschlussbedingungen (TAB)”, “Aufschaltbedingungen”, “Anschlussbedingungen” or even “Merkblatt”. What is always meant are the conditions for connecting a fire alarm system to the fire brigade. The table therefore shows the title under which each document is published.

Sources: Where the fire protection authority publishes its document itself, we link to it. Entries marked (Fachportal) come from the TAB collection of din-14675.de, which lists newer documents as “AB” (Anschlussbedingungen) and older ones as “TAB”. The portal accepts no liability for these versions – please have them confirmed by the fire protection authority before planning. Municipalities with their own conditions are not listed.
