The annual expert inspection in accordance with the applicable proofs of usability is the central legal evidence that your hold-open system is operable — performed by a trained specialist contractor. Our inspection team documents every detail, traceable for authorities, expert assessors and insurers.
The expert inspection differs from maintenance (upkeep, adjusting, replacing) and the operator's monthly function test. It comprises a complete, standards-compliant check of all safety-relevant functions — smoke-detector sensitivity, reaction time, holding force, closing speed, battery status, self-test. It must be performed by an expert person with the appropriate qualification and manufacturer training and culminates in a written inspection record with defect classification (A/B/C). The record is the central basis for fire inspections, expert assessment and insurance evidence.
Which variant fits depends on the installation context, the existing building and the fire-protection concept — we advise per project.
Cost-efficient solution for the most common installation contexts — tested systems from established manufacturers.
For non-standard sizes, installation contexts or higher requirements driven by the fire-protection concept or expert reports.
Recertification of existing components or phased replacement — coordinated around live operations.
All prices excl. VAT. Maintenance contracts are quoted on a per-unit basis.
We cover every typical building type — from residential to industrial complexes with hundreds of components per site.
Apartment buildings, stairwells, transitions to boiler rooms and underground garages — usually with smoke-protection properties.
Separation of production, storage and administration plus protection of mechanically loaded plant.
Schools, hospitals and administrative buildings under NRW special-buildings regulations — often combined with hold-open systems.
German baseline standard for classifying building components under fire exposure.
Test method and classification under EN 13501-2 — basis for CE marking.
Basis for annual maintenance duties and audit-ready inspection records.
NRW Building Code and special-buildings regulation — binding for all special-purpose buildings.
Structured, measurable, standards-compliant — each step with measured value and finding in the record.
Demonstrable qualification as a competent person for hold-open systems, manufacturer-certified for all common systems.
