The fire alarm concept according to DIN 14675 Section 5 forms the basis for planning a fire alarm system. It takes into account the requirements of building law, the fire brigade, occupational health and safety, insurers and the building operator.

Thus, it summarises the basic requirements for system components as well as the connection to the fire brigade and other (fire protection) facilities. Accordingly, it is an essential component for optimal and legally compliant planning, installation and operation of the fire alarm system.

Fire alarm concept in detail

The fire alarm concept must be drawn up in close coordination with the authorities, fire brigade, insurer, specialist planner and installer.

The responsibility for the preparation, completeness and accuracy of the fire alarm concept according to DIN 14675 lies with the client of the fire alarm system. The client may commission a specialist company to prepare the concept.

The fire alarm concept according to DIN 14675 must contain at least the following information:

  • Building description (type and use)
  • Protection goal
  • Scope of monitoring - categories 1 to 4
  • System structure (incl. emergency power)
  • Location or access to the FACP and FIZ
  • Type of alarm (internal/external)
  • Measures to prevent false alarms (based on environmental influences and disturbance variables)
  • Connection to the fire brigade
  • Specifications for fire control
  • Specifications for documentation (operating log)
  • Specifications for maintenance and testing

Monitoring scope according to DIN 14675

The scope of monitoring to be defined according to DIN 14675 is divided into four areas. In addition, the building operator has the option to include other building areas in the fire alarm system planning that are not required from a building law or insurance perspective.

1. full protection

Full protection covers all areas of the building. This means that all rooms, ventilation systems, ducts and shafts are equipped with fire detectors and monitored. The only exceptions are rooms with a very low fire load, e.g. sanitary rooms, or ducts with fire-resistant partitions.

2. partial protection

Partial protection is limited to particularly endangered building areas. The separation of the building areas with and without surveillance must be ensured with at least one fire-resistant wall or ceiling.

3. protection of escape routes

The protection of escape routes is limited to all building areas that are adjacent to an escape and rescue route or through which it leads. In addition, there are rooms in which a fire cannot be detected by people at an early stage, e.g. in the archive or technical room.

4. facility protection

Facility protection focuses on the protection of material assets (e.g. valuable goods or technical equipment) and not on personal protection. It is used, for example, in museums, production facilities or data centres.

Let a fire alarm concept be created

The creation of a fire alarm concept requires expert knowledge of the legal requirements. The basis for this is the fire protection concept, the building permit or insurance requirements.

Do you need a fire alarm concept?

The experienced team at CWS Fire Safety prepares fire alarm concepts in accordance with DIN 14675. After preparation, they are submitted to the fire brigade (or fire protection service), the expert and the operator for inspection and approval. We then carry out the planning, installation and maintenance of the fire alarm system.
