Secure, fast and reliable. Easy to expand and compatible with the electronic locking systems from DOM, RS Sigma is future-proof and thus protects your investment in the long term!

This system can be ordered as a locking system in our locking system configurator or as a reorder.

Advantages:

High security, high manipulation protection

The up to 19 locking authorisation queries per key make it almost impossible to overcome the cylinder. 6 solid pin locking elements and lateral profile control pins make unauthorised opening with duplicate keys more difficult.

Key copy protection

The key profile is protected by design patent and protects against unauthorized key copies.

High comfort

Easy handling of the key due to the ergonomically shaped key head.

Options / Special equipment:

different cylinder finishes (polished brass, oxidized bronze)
emergency and danger function
increased drilling protection + modular design = VdS AZ (VdS**)
freewheel
weather protection
modular technology with increased tear-off protection

Explanations on the optional extras:

Drilling protection VdS AZ:

In cooperation with the police, VdS Schadenverhütung GmbH has developed a star system that divides mechanical locking systems into three different security classes, thus providing you with a quick overview of the respective security level.

recognition by VdS Schadesverhütung GmbH
VdS checks locking systems and awards recognition from A to BZ+
drilling protection + modular design = VdS AZ (VdS**)
VdS AZ+: increased protection against drilling and core pulling due to carbide pins in cylinder body and cylinder core arranged in several levels
this drilling protection variant is manufactured in modular technology with increased tear-off protection

Cylinder finishes:

finishes (polished brass, oxidized bronze)
standard finish: dull nickel
for individual design requirements
on request for 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.

dull nickel

polished brass

oxidized bronze

Seawater resistance:

for use in marine climate or salty atmosphere
fixing screw pure brass, cam sintered steel (chemically nickel plated)
cylinder finish: matt chrome
restrictions possible in combination with other optional equipment
in combination with freewheel: clutch not protected against seawater

Freewheel:

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. DOM freewheel cylinders comply with DIN EN 18252:2006-12.
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.

from cylinder length: 35,5/35,5 mm
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
with this option the cylinder has no emergency and danger function
freewheel function is tested according to FZG (test guideline for profile cylinders with freewheel function for gear locks in escape door locks)
