NotausTürbeschläge

NotausTürbeschläge, also known as emergency exit door fasteners, are specialized fittings designed to secure fire and security doors while ensuring rapid, safe egress in emergency situations. They consist of a combination of hinges, latch, and lock mechanisms that allow the door to remain sealed against fire and noise but can be quickly released from the inside during an alarm.

The most common type of NotausTürbeschlage is the push‑to‑open latch, often called a "Schließmechanismus" or "auslösendes Anschlag". When the door is closed, the latch holds it in place despite pressure from the fire or static. Inside, a simple push or pull lever disengages the latch, permitting the door to swing open. For high‑security environments, a three‑way lock is used, which can be released either by a key or by a concealed internal handle, ensuring that the lock cannot be forced open from the outside without appropriate access.

Installation standards for NotausTürbeschläge are governed by national building codes such as the DIN 1936 in Germany, the EN 1125 series in Europe, and the NF DT 39 in France. These codes prescribe the required fire rating, opening speed, and separation distance. Compliance is verified through testing by certified laboratories.

In modern buildings, NotausTürbeschläge are often integrated into a broader fire safety system, including alarm triggers, automatic release, and barriers or door chains. They play a critical role in maintaining occupant safety and in meeting insurance and regulatory requirements.
