Completely in the door frame

Fully motorised security door locking device providing freedom of door sash design and simple frame keep installation – without wiring to the doorstile.

The secret of the blueTop system

All of the locking system’s technical components are completely housed in the solid door frame. The advantage is immediately apparent, since it is not necessary to integrate any locking elements into the door sash. This allows you to realise your own individual ideas in doorstile design without any restrictions. The blueTop multi-point locking system can even be rendered without a profile cylinder and handle set for those who love straight-lined design.

Locking and unlocking

When closed, the blueTop locking system’s motor automatically extends two solid 110mm long bolts.
There is also a function for mechanical opening from the inside for use in emergencies.

Access organisation

The blueTop can be opened via a contact-free interface in all standard access control systems or building networks which feature a potential-free contact.
