What is a fire door lock?
A fire door lock is a specially developed door lock designed for use on fire doors. It not only provides protection against unauthorized access, but is also certified according to DIN EN 12209 for mechanical locks. Versions with panic function additionally comply with the European standards DIN EN 179 (emergency exits) and DIN EN 1125 (panic doors). Such a lock secures fire doors against fire and smoke to keep escape routes open and safe in the event of a fire.

Fire door locks combine reliable locking technology with tested security according to DIN 18251 as well as EN 179 and EN 1125. They meet the highest requirements for fire protection and escape safety – ideal for doors in public buildings, administrations or commercial construction.
