Motor-driven bolt locks for timber and steel doors
Motor-driven bolt locks for timber and steel doors meet the highest requirements for security, convenience, and controllability. Thanks to their compact design, variable backset dimensions, and precise bolt technology, they are ideal for use on double-leaf doors – both in new buildings and for retrofitting.
The automatic locking of the inactive leaf provides maximum protection while ensuring high user convenience. Unlocking is performed electrically, e.g. via an access control system or a swing door operator.
The locks are certified to EN 179 and EN 1125 for use in escape and rescue routes. In combination with monitoring contacts, panic functions, and electronic controls, motor-driven bolt locks offer a powerful solution for security-critical applications in public, commercial, and sensitive areas.

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.
