DORMAKABA gemini plus

DORMAKABA gemini plus benefits from a high level of security thanks to the sophisticated technology within the locking cylinder. DORMAKABA gemini plus locking cylinders protect against the most common opening methods (picking and impact protection).

DORMAKABA gemini plus cylinders are part of an ergonomically correct reversible key system, which means that the DORMAKABA reversible key is inserted vertically into the cylinder channel. The locking positions on each side of the cylinder are arranged in 3 rows radially around the key. The cylinder is thus reliably protected against illegal opening methods - even with modern tools.

The patented reversible key system is suitable for small to medium-sized locking systems with high demands.

This system is available for reorders only.

For new systems, we offer the DORMAKABA expert plus series.

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.

DORMAKABA gemini plus cylinder cross section

Execution:

ergonomically correct reversible key, i.e. the DORMAKABA reversible key is inserted vertically into the cylinder channel
easy key insertion due to new design of the locking elements
cylinder body: nickel plated brass
integration into electronic DORMAKABA locking systems with LEGIC clip possible at any time (retrofittable), mechanical lock remains unchanged

Key:

key thickness: 2,5 mm
reversible key made of high-quality nickel silver, low-wear
reversible key that is technically difficult to copy
the coding of the keys is not done by drilling, but by a special milling process that conceals the position of the coding on the key
the new coding on the tip of the key cannot be produced with conventional key cutting machines; if the coding is missing, a key cannot be inserted or turned
high breaking resistance
3 different key types, standard key: smartkey (optional largekey, long bow)
colour clip standard: dark blue (selectable from 12 colours)

Operational area:

private houses and apartments
small and medium-sized enterprises
small and medium-sized locking systems

Options / Special equipment:

different cylinder finishes
increased drilling protection according to VdS B, increased drilling and pulling protection according to VdS BZ
emergency and danger function (closing on both sides)
priority (the key locks from outside if there is a key inside) (on request)
freewheel (from 70 mm total length, on request)
weather protection
long bow with and without key clip

Explanations on the optional extras:

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 mit Hartmetallstiften = BS
B = Hartmetallbolzen
C = Bible-Schraube
D = Insertbefestigungsschraube gehärtet
E = Stahllamelle

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.

nickel plated

brass natural

brown medium

black

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 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.

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 finish).

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.

Freewheel (on request):

The profile cylinders which have a freely rotating cam are designated as freewheel cylinders.
The cam can be moved freely through 360° 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
