Mechanical locking systems are the foundation of organisational building security. A combination of electronically controlled security technology creates all-encompassing security solutions.
DPI keys can be designed as Combi Keys that carry identification technology (e.g. Mifare, Legic, iButton etc.). This transforms the mechanical key into an electronic ID.
Motorised cylinders can be integrated into a DPI master key system. These cylinders can be locked and unlocked with an electronically powered motorised knob.
Very often mechanical locking systems are used in combination with electronic access controls. This means that all different types of door can be equipped with suitable security technology, according to their specific level of protection.
Due to the robustness and stability of mechanical locking systems, they are often required for use in emergency service buildings (e.g. fire brigade) as mechanical emergency locks (overlocks) for electronic systems.
