What is a fire door lock?
A fire door lock is a specially designed door lock intended for use on fire doors. It not only ensures protection against unauthorized access, but is also certified in accordance with 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, keeping escape routes open and safe in the event of a fire.
