Standards and safety requirements
Motor locks for timber and steel doors meet the highest safety standards in accordance with EN 12209 and DIN 18251. In combination with panic function, they also comply with the European standards EN 179 (emergency exits) and EN 1125 (panic doors). Thanks to motorized locking and optionally integrable monitoring contacts, they are particularly suitable for doors with increased requirements for controllability and access control. Many versions are VdS-certified, suitable for escape routes, CE-marked, and offer fire and smoke protection suitability for use throughout Europe.
suitability for fire protection
Approved for use on fire and smoke protection doors
Emergency exit devices with lever handle or push plate for doors in escape routes
The EN 179 standard refers to emergency exit devices intended for use in buildings where it is expected that people familiar with the escape route can quickly and safely reach an exit in an emergency. These locking systems are designed to be easily opened in the event of an emergency. They require only a simple hand movement without the use of keys or similar aids. EN 179 specifies requirements for the design and performance of such systems to ensure their reliability and safety.
panic-break-out hardware with horizontal operating bar
DIN EN 1125 refers to panic exit devices with integrated latch that are equipped with a horizontal operating bar. This standard specifies the requirements and test methods for emergency exit devices intended for use in public buildings to ensure a quick and safe exit in case of emergency. The devices must be designed so that they can be easily operated even under panic conditions.
Electromechanical locks and electric strikes
The DIN EN 14846 standard specifies the requirements and test methods for electromechanical locks and strike plates. This standard covers both motorized and electromagnetically operated locking systems that can be installed in doors. It addresses aspects such as security, functionality, and reliability of the locks under various operating conditions.
