Investment security
Investment security and upward compatibility - in short, long service life and suitability for use of products once purchased - have always been an important issue for and a key differentiator of DORMAKABA.
The modular design and the possibility of retrofitting the locking system and equipping mechanical keys with RFID transponders guarantee flexibility and secure your investment for years to come.

DORMAKABA modular
The DORMAKABA modular system allows cylinders to be converted to other lengths or even other cylinder shapes on site with little effort. The locking system remains intact.
The inserted cylinder cores (inserts) can easily be used in other cylinder designs (half cylinders, knob cylinders, camlock cylinders, etc.).

Organisational protection through security card
Every new DORMAKABA gemini plus master key system and every standard cylinder is supplied with a security card containing all the security details of the system or single lock. This card is used to order duplicate keys and to register and manage the master data of the master key system or single lock.

International certifications
DORMAKABA gemini plus is internationally certified several times against cylinder break-up by drilling, pulling, picking and bumping.

Versatility
The DORMAKABA gemini plus system makes it possible to cover each user's individually applicable authorizations within the locking plan hierarchy with a single key - in the private or business sector.

Largekey (clip and long bow)

• long key bow with extended key neck
• colour clip standard: dark blue (selectable from 12 colours)
• when using e.g. protective fittings with core pulling protection rosette

Long bow (armour bow)

• reversible key with armour bow
• when using e.g. security fittings with core pulling protection rosette and multiple locking systems

Cylinder finishes

• standard finish: nickel plated (silver-coloured)
• optional: brown medium, brass natural (gold-coloured), black
• for individual design requirements
• if desired, homogeneous appearance of door cylinder and fitting
• Please note:
  If a different cylinder finish, different from the standard finish, is ordered, extended production times may occur.

Standard drilling protection

The standard drilling protection is achieved by standard hardened steel locking elements and a hardened insert fixing screw (A). This design complies with DIN EN 1303 attack resistance class B.

Increased drilling protection - VdS class B approval

By using additional steel elements in the body and insert, a higher resistance to drilling is achieved. Class B locking cylinders do not have an integrated pull-out protection. In combination with a tested core protection fitting, attack resistance class D is achieved.

A = insert with two carbide longitudinal pins = BS
B = tungsten carbide stud
C = short insert fixing screw hardened at the front
D = long insert fixing screw hardened at the rear

Increased drilling and pulling protection - VdS class BZ

By using additional steel elements in the body and insert, a higher resistance to drilling is achieved. The increased pulling protection values are achieved by means of a pulling protection pin.
The new DORMAKABA VdS cylinder protects against pulling even in tubular frame doors.
These cylinders can be used without protective fittings and achieve attack resistance class D without a tested core protection fitting.

A = insert with carbide pins = BS
B = tungsten carbide stud
C = bible screw
D = insert fixing screw hardened
E = steel lamella

Emergency and danger function

This function enables the locking cylinder to be blocked even if a key with blocking authorisation is inserted on the opposite side.

Dust and splash water protection

Cylinders with dust and splash water protection are equipped with a spring-loaded dust and weather protection cap with 2 spring-loaded sealing lips on the cylinder face. Every Euro profile cylinder can be equipped with this function. The outside and/or inside length of the cylinder is extended by approx. 5 mm in each case.

Dust and splash water protection is supplied in standard color nickel plated (silver colour).

Cannot be used for cylinders with pulling protection devices and for protective fittings.

Note:
This function is side-dependent. It is therefore necessary to select the respective cylinder side with dust and splash water protection function when ordering. The double-sided version is possible.

Dust and insect protection (on request)

The new SIS element is optimised for use with Euro profile cylinders and offers effective protection against the penetration of dirt and insects into the key channel. The outside length of the cylinder is extended by approx. 3,5 mm.

The SIS unit can be easily retrofitted as it is decoupled from the body and is mounted directly on the rotor. As a result, only the cylinder insert needs to be replaced, the rest of the cylinder is not affected by the upgrade and can continue to be used 1:1.

If the cylinder front is to be on one level, the option dust and splash water protection must be selected.

Not available in conjunction with VdS versions.

The SIS cap is always chemically nickel-plated.

Note:
This function is side-dependent. It is therefore necessary to select the respective cylinder side with dust and insect protection function when ordering. The double-sided version is possible.

Special locking cams for profile cylinders (on request)

• 2-fold cam (Biffar)
• Mul-T-Lock pinion with 10 teeth cog

b = width of the locking cam

Freewheel (on request)

The profile cylinders which have a freely rotating cam are designated as freewheel cylinders.
The cam can be moved 360° freely when no key is inserted.
When the key is inserted, the spring-loaded clutch engages in the cam. This then allows the cylinder to be closed in the conventional way with the key.

• Usually only necessary for special panic or automatic locks. If in doubt, please check with the door manufacturer.
• for multi-point locks with panic function: latch and bolt must be moved into the lock body when the door is closed with the handle. To ensure this, the cam must be able to turn freely.
• in motor-driven locks and special escape door locks
• restrictions possible in combination with other optional equipment
• certified for transmission and anti-panic locks
• from 70 mm total length possible

Cam position - carrier adjustment:

standard setting: 30° right with marking point seen from the front of the cylinder

• 1. unscrew the cover on the back of the cylinder using a coin or screwdriver
• 2. remove clutch and driving hub
• 3. set up the cylinder on the template and turn the driver to the desired position
• 4. push the driving hub into the body according to the sketch
• 5. insert the clutch into the driving hub
• 6. screw the cover back in until it is level with the body
