The fire alarm system planning process follows the phases of DIN 14675 and DIN VDE 0833, beginning with needs assessment and risk analysis. It is followed by the basic evaluation, preliminary design, approval planning, tendering, detailed design, installation, acceptance and finally documentation and maintenance. Manufacturer-independent planning is decisive here for economic efficiency and legal compliance.

A manufacturer-independent perspective for complex fire detection systems

Planning a fire alarm system is a multi-layered process that goes far beyond the mere installation of detectors. Errors in the concept can have serious consequences for safety, cost and legal compliance. Find out how a structured fire alarm system planning process lays the foundation for a reliable, future-proof fire detection system.

Phase 1: Needs assessment and risk analysis, the foundation of every fire alarm system plan

Every successful fire alarm system planning process begins with a detailed needs assessment and a comprehensive risk analysis. This first phase is decisive for understanding the property's specific requirements and clearly defining the protection objectives. It is about identifying not only the obvious risks, but also potential hazard sources and operational particularities. The legal foundations and standards, such as DIN 14675 and VdS 2095, serve here as the governing frameworks. DIN 14675 describes the phases for the planning, installation and operation of fire alarm systems and requires the creation of a fire alarm concept as a precondition for planning. VdS 2095 specifies these requirements further and gives detailed guidance for the planning and installation of automatic fire alarm systems.

In this phase, the type and use of the building, the number of people, the type of stored materials and the potential fire loads are analysed in detail. One example is a logistics centre with high-bay racking for combustible goods, which has entirely different requirements for a fire alarm system than an office building or a data centre. The risk analysis assesses the probability of a fire event and its potential impact. Based on these findings, the protection objectives are set: is the primary concern the protection of people, the protection of assets, or ensuring business continuity? Often it is a combination of these objectives. The results of this phase feed into an initial fire alarm concept, which forms the basis for all further planning steps and also determines measures for avoiding false alarms as well as the type of remote and internal alerting.

Phase 2: Basic evaluation and preliminary design, precisely implementing normative requirements

After the initial needs assessment comes the phase of basic evaluation and preliminary design. Here, the protection objectives and requirements defined in the fire alarm concept are translated into technical specifications. This includes a detailed survey of the structural conditions, the existing infrastructure and the interfaces with other technical systems in the building. DIN VDE 0833-2, which sets out provisions for fire alarm systems, is a central body of rules here that planners, installers and operators alike must observe. Among other things, it specifies that the operator is responsible for the fire alarm and alerting concept and must determine the measures jointly with the planner and installer.

An essential part of this phase is drawing up a detailed specification of services covering all the necessary components and services of the fire alarm system. This includes selecting suitable detector types (e.g. smoke detectors, heat detectors, flame detectors, aspirating smoke detectors), their number and arrangement, the networking of the detectors and the cabling. The power supply of the fire alarm system in accordance with DIN EN 54-4 and the requirements for the fire alarm control panel (BMZ) under DIN EN 54-2 must also be taken into account here. Preliminary design also serves to coordinate with the relevant authorities, such as the fire brigade and building control offices, to clarify possible conditions and approval requirements at an early stage. This minimises later delays and ensures that the planned system meets public-law requirements. Precise documentation of all decisions is of the utmost importance in this phase, to ensure transparent and traceable planning.

Phase 3: Detailed design, manufacturer-independent system selection and technology integration

Detailed design is the phase in which the fire alarm concept and preliminary design are translated into a concrete technical design. Here, the manufacturer-independent selection of system components is the priority, to ensure an optimal solution without unnecessary dependence on manufacturers. PLANATEL® places great value on ensuring that the selection of the fire alarm control panel, the detectors and the alerting devices is based exclusively on technical criteria, suitability for the specific property, and economic efficiency. The EN 54 series of standards, which comprises European product standards and application guidelines for fire alarm systems, is a decisive reference work here. It defines, for example, requirements for audible alarm devices (EN 54-3), heat detectors (EN 54-5) and point-type smoke detectors (EN 54-7).

In this phase, detailed plans are drawn up showing the exact positioning of detectors, signal devices, manual call points and the fire alarm control panel. An important aspect is the integration of the fire alarm system into the existing or planned building technology. This includes interfaces with other hazard detection systems such as intrusion detection systems (EMA), access control systems, smoke and heat extraction systems (RWA) or lift controls. The compatibility and smooth interaction of these systems is decisive for effective fire-event control. Detailed design also takes into account the scalability of the system, to accommodate future expansions or changes in the building's use. By considering these aspects early on, later conversions or adjustments can be realised with significantly less effort, which saves costs in the long term and protects the investment. Detailed elaboration of the fire event matrix, which sets out how the system behaves in different alarm scenarios, is likewise a central part of this phase.

Phase 4: Approval planning and tendering, paving the way to realisation

Once the design of the fire alarm system has been worked out in detail, the phase of approval planning and tendering follows. Approval planning includes preparing all documents needed for the official approval of the fire alarm system. This includes technical drawings, descriptions of system functions, evidence of conformity with DIN 14675, DIN VDE 0833 and EN 54, and, where applicable, further supporting documentation. Coordination with the relevant authorities and the fire brigade is of decisive importance in this phase, to ensure that all conditions are met and approval is granted smoothly. The requirements of the local technical connection conditions (TAB) of the fire brigade must also be observed, as these contain specific requirements for the connection and components of the fire brigade interface (e.g. fire brigade indicator panel, fire brigade control panel, fire brigade site plans, fire brigade key depot).

In parallel with approval planning, the tender for the installation of the fire alarm system is prepared. A precise and complete description of services is essential here, to obtain comparable quotes from qualified installers. The tender documents comprise the detailed specification of services, technical specifications, schedules and contractual conditions. PLANATEL® supports its customers in preparing these documents, to ensure a manufacturer-independent wording and avoid unnecessary costs from excessive requirements or proprietary solutions. The selection of the appropriate installer is made on the basis of a transparent evaluation of the quotes, taking into account not only price but also technical competence, certifications (particularly under DIN 14675) and the provider's references. A careful tender process is the key to an economical, high-quality implementation of the project.

Phase 5: Detailed construction planning and project support, quality assurance during implementation

With approval granted and the installer selected, the phase of detailed construction planning and project support begins. In detailed construction planning, the design and approval plans are worked out down to the last detail. This includes preparing installation plans, wiring diagrams, cable-run lists and detailed installation instructions. The aim is to give the installer a precise basis for installing the fire alarm system that leaves no questions open and avoids misinterpretation. The exact positioning of every detector, every siren and every control component is determined, to ensure optimal function and coverage in accordance with the normative requirements and the protection objectives. DIN VDE 0833-2, for example, sets out clear requirements for the planning and arrangement of signal devices, to ensure unambiguous alerting.

Throughout the entire installation phase, PLANATEL® provides independent project support and quality assurance. This includes regular site inspections, checking that the installation is carried out properly in accordance with the planning documents and the applicable standards (DIN 14675, DIN VDE 0833, EN 54). We ensure that the components used meet the specifications and that the installation meets the highest quality standards. Any deviations or defects are identified and rectified at an early stage, to avoid costly rework in later phases. Project support also includes coordination between all parties involved (the client, the installer, the authorities and other trades) to ensure a smooth process and adherence to schedules. This independent oversight is essential to protect the client's interests and ensure that the contractually agreed services are delivered.

Phase 6: Acceptance, documentation and training, the path to legally compliant handover

Acceptance marks the conclusion of the installation phase and is a critical step in the fire alarm system planning process. Here, the fire alarm system's full functionality and legal compliance are checked. Acceptance is generally carried out by an independent expert, often in the presence of the operator, the installer and the planner. Comprehensive functional tests are carried out, covering all components of the system and the fire-event controls. This includes triggering detectors, checking alerting (audible and visual), the correct activation of interfaces to other systems (e.g. RWA, lifts) and the correct connection to the fire brigade. The VdS 2095 guideline gives detailed requirements for commissioning and acceptance.

In parallel with acceptance, the complete documentation is prepared and handed over. This includes revision plans, operating logbooks, test protocols, maintenance instructions and declarations of conformity. Complete documentation is essential not only for legal compliance, but also for later operation, maintenance and any extensions to the system. Under DIN VDE 0833-1 and -2, the operator is obliged to keep an operating logbook and ensure it is complete. Another important aspect is training the operator's staff. The instructed persons must be able to operate the fire alarm system, recognise faults and initiate first measures. PLANATEL® supports the creation of maintenance concepts and the selection of certified installers for subsequent servicing, to ensure the long-term functionality and safety of the system.

The decision in favour of independent planning in the fire alarm system planning process is of fundamental importance for the legal compliance and long-term economic efficiency of a fire alarm system. As a manufacturer-independent planner and consultant, PLANATEL® is financially independent and receives no commissions from manufacturers or installers. This enables objective advice and planning oriented exclusively towards the customer's needs. Compliance with statutory requirements and relevant standards such as DIN 14675, DIN VDE 0833 and EN 54 is always ensured. Design and installation compliant with the standards significantly reduces the liability risk for the responsible operator.

The advantages of manufacturer independence are also evident in cost optimisation. Through the free selection of the best components on the market and the avoidance of manufacturer dependencies, investment and operating costs can be significantly reduced. A fire alarm system incurs not only acquisition costs, but also ongoing costs for maintenance, testing and, where applicable, spare parts. Independent planning considers the entire life cycle of the system and aims for a solution that can be operated reliably and cost-efficiently for decades. Our over 34 years of experience in planning complex infrastructure projects, including fire detection systems, enables us to identify and minimise risks at an early stage, develop tailored solutions and represent our customers' interests optimally. This leads to greater investment security and sustainable value preservation for your technical systems.

Common mistakes in the fire alarm system planning process and how to avoid them

Despite clear normative requirements, mistakes with far-reaching consequences repeatedly occur in the fire alarm system planning process. One of the most common mistakes is an inadequate needs and risk analysis. If the fire alarm concept is skipped or only superficially prepared, this often leads to an incorrectly dimensioned system that is either oversized and therefore too expensive, or fails to provide the required protection in an emergency. Another critical point is insufficient coordination with authorities and the fire brigade in the early planning phases. This can lead to subsequent conditions being imposed, causing significant redesign and additional costs.

Another mistake is focusing on the pure acquisition costs without considering the fire alarm system's life-cycle costs. Cheap components can prove more expensive in operation through higher maintenance and spare-parts costs or increased power consumption. Missing or inadequate documentation is also a recurring problem that complicates operation and maintenance and jeopardises legal compliance. DIN VDE 0833-1 prescribes annual maintenance, the documentation of which must be verifiable in the operating logbook. PLANATEL® helps avoid these pitfalls by ensuring a structured, standards-compliant and manufacturer-independent planning process. We place value on a comprehensive needs analysis, early coordination with all parties involved, and a detailed life-cycle cost assessment. Our expertise ensures that your fire alarm system not only meets current requirements, but can also be operated in a future-proof and economical manner.

Frequently asked questions

Why is manufacturer-independent planning so important for fire alarm systems?

Manufacturer-independent planning ensures that the selection of components and systems is based exclusively on technical requirements, suitability for the specific property, and economic efficiency. Without financial dependencies on manufacturers, an independent planner such as PLANATEL® can find the objectively best solution for the customer. This avoids unnecessary manufacturer dependencies, optimises investment and operating costs over the entire life cycle of the system, and secures long-term value preservation. Legal compliance is also ensured through strict adherence to all relevant standards and guidelines.

What role does DIN 14675 play in the fire alarm system planning process?

DIN 14675 is the central German standard for fire alarm systems and voice alarm systems. It structures the entire life cycle of a fire alarm system into phases, from concept creation through planning, installation and acceptance to operation and servicing. It sets out not only technical requirements, but also the competencies of specialist firms active in the various service phases. Compliance with DIN 14675 is decisive for legal compliance and the certification of the fire alarm system.

What cost factors need to be taken into account when planning a fire alarm system?

The costs of a fire alarm system are varied and include not only the pure acquisition and installation costs. Key factors are the size and use of the building, the type and number of detectors, the complexity of the fire-event controls, and integration with other systems. In addition, the ongoing operating costs for maintenance, inspection, testing, spare parts and energy consumption over the entire life cycle of the system must be factored in. Independent planning helps make these costs transparent and optimise them over the long term.

What is a fire event matrix and why is it important?

The fire event matrix is a central document in fire alarm system planning that sets out the defined behaviour of the fire alarm system in different alarm scenarios. It describes in detail which actions should occur automatically when specific detectors or detector groups are triggered. This can include alerting the fire brigade, activating visual and audible signal devices, controlling smoke and heat extraction systems, releasing escape doors, or switching off ventilation systems. The fire event matrix is decisive for effective fire-event control and the protection of people and property.

How does PLANATEL® support the selection of the right installer for fire alarm systems?

PLANATEL® supports its customers by preparing precise, manufacturer-independent tender documents that enable transparent and comparable quotes. We evaluate the incoming quotes not only on price, but also on technical competence, required certifications (particularly under DIN 14675), and the references of the potential installers. Our goal is to find a qualified and reliable partner for installation who implements the planned fire alarm system in accordance with the highest quality standards and normative requirements, without losing sight of economic efficiency.

Which standards are relevant for planning fire alarm systems?

The standards primarily relevant for planning fire alarm systems are DIN 14675 (structure and operation of fire alarm systems), DIN VDE 0833-1 and -2 (hazard detection systems) and the European EN 54 series (product requirements for components). VdS 2095 additionally specifies the requirements for planning and installation.

What is the difference between a fire alarm system (BMA) and a fire warning system (BWA)?

A fire alarm system (BMA) under DIN 14675 is a complex system for early fire detection that is generally connected directly to the fire brigade and is a legal requirement in many special-purpose buildings. A fire warning system (BWA) under DIN VDE V 0826-2 is a local warning system for evacuation that does not automatically trigger an emergency call to the fire brigade, and is often used in buildings without a legal requirement for a fire alarm system, such as smaller hotels or day-care centres.

Who is responsible for the fire alarm concept?

Under DIN VDE 0833-2, the operator of a fire alarm system is responsible for the fire alarm and alerting concept. The operator determines the necessary measures jointly with the planner and, where applicable, the installer. A detailed fire alarm concept is, under DIN 14675, the precondition for further planning.

How often does a fire alarm system need to be maintained?

DIN VDE 0833-1 prescribes annual maintenance for fire alarm systems. In addition, regular inspections of the monitored areas must be carried out at least quarterly by knowledgeable persons or qualified electricians, to ensure the system's functionality and to document this in the operating logbook.
