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.
