Services · Fire alarm systems

Fire alarm systems from design to maintenance – from one certified contractor.

Certified under DIN 14675 for every phase from design to maintenance. The responsible person is on our staff – not at an outside consultant.

A fire alarm system is not a product you buy and mount. It is a life cycle: design based on the fire safety concept, engineering with the inspector, installation during ongoing operation, commissioning, acceptance, then decades of maintenance. The German standard DIN 14675 divides this path into phases and requires a certified contractor with a named responsible person for each of them.

HD-Überwachung is certified for phases 6.1 to 11 (ZDS certification body for security technology, DAkkS-accredited; first certified 2022, recertified until 2030). The responsible person under DIN 14675 is the owner himself. For you that means one contact across the entire life of the system and no hand-over losses between designer, installer and maintenance contractor.

Systems we work with

New systems are built exclusively with Telenot hifire – we have been a trained Telenot installer for fire alarm, intrusion alarm and transmission systems since 2021. Existing systems of other makes we take over for maintenance or conversion where documentation and spare parts allow; we have the measuring and field-bus equipment for fault finding.

How it works

How a fire alarm project runs with us

Site visit and documents

We review the fire safety concept, building permit and existing system documentation and clarify what the inspector will want to see.

Concept and fixed price

Detector concept, transmission path, fire brigade interfaces – as a quote with items you can follow.

Installation during operation

Our own staff, our own aerial work platform, scheduling around your business. Fire stopping is done at the same time.

Acceptance and hand-over

We prepare the documentation, accompany the inspector's test and train your staff.

Subcontracting

For system integrators and general contractors

We have worked as a subcontractor for nationwide system integrators since 2018 and as an installation partner of Chubb since 2022. Installation, conversion, commissioning and service of alarm systems as a subcontractor – with all formal credentials (DIN 14675 certified contractor, responsible person, manufacturer training). Company profile with certificates on request.

FAQ

What customers ask us about fire alarm systems

When is a fire alarm system mandatory in Germany?

When the building permit, the fire safety concept or the insurer requires it – typically hotels, assembly buildings, care facilities and larger commercial and industrial buildings. The fire safety concept states whether and what scope is needed; we go through it with you.

What does “certified contractor under DIN 14675” mean?

The standard requires a certified contractor with an examined responsible person for design, installation, commissioning, acceptance and maintenance. We are certified for all of these phases and present the certificates on request.

How often does a fire alarm system need maintenance?

Under DIN VDE 0833-1 at least one maintenance per year plus quarterly inspections, some of which the operator can carry out. The exact scope is defined in the maintenance contract.

Can you take over a system from another manufacturer?

In most cases yes. We check documentation, spare parts availability and condition and tell you openly whether taking it into maintenance makes sense or a conversion to Telenot would be more economical.

Do you work in English?

Yes. Site visits, quotes and documentation hand-over in English are no problem; the formal documents for the German inspector are produced in German as required.
