Hold-open systems keep fire doors open in daily use and close them automatically on smoke detection. They combine everyday convenience with reliable fire-event safety — they require approval (DIBt) and must be checked monthly by the operator and annually by a specialist contractor.
A hold-open system is a technical assembly that keeps a self-closing fire door open in daily use and triggers automatically on smoke or power loss. It comprises a magnetic holder that retains the door, a smoke detector to detect fire, a trigger device that interrupts the magnet's power, and the power supply with battery backup. Each system requires DIBt approval. Hold-open systems are the legally permitted alternative to a permanently closed fire door — important for accessibility, comfort and reduced wear in corridors, stairwells and high-traffic areas.
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.
Each hold-open system needs its own DIBt approval — no operation without approval.
