Types of locking systems

A locking system is used whenever more than one door is to be locked and unlocked.  Locking systems can also serve as an organizational tool since they allow the implementation of hierarchically structured access authorizations.

Locking systems can map internal organizational structures or reflect the typical uses of the building.

A locking system should always be planned in close cooperation between the developer and the planning office.  Only this will ensure that an ideal structure is  found that affords the flexibility to make changes and extensions even years after its initial installation.

Which type of locking system is installed depends on the specific requirements.

The master key system
One for all

A doctor has a master key that operates both the lock on the entrance door to his home and the locks on the office doors. His staff has keys that only operate the locks on the office doors.

Possible applications: law offices, doctors' offices, small enterprises, etc.

The central locking system/maison key system
Common entrances

In a multiple dwelling, each tenant has a key that will open his or her own flat, post box and cellar compartment.  All tenants can use their key also to open common entrances such as the front door or the door leading to the basement.  In this type of locking system, there is no higher-order master key.

Possible applications: rental flats



The grand master key system
Unlimited organizational freedom

Basically, a grand master key system is a combination of several master key systems with a higher-order grand master key.  With CES grand master key systems, even the largest building complexes can be managed systematically.  Apart from the grand master key, which can operate all of the cylinders in the locking system, there are group master keys, group keys and sub-group keys on various hierarchical levels. CES grand master key systems are used wherever complex access authorizations must be implemented.

Possible applications: airports, large building complexes, etc.
