DPS Technology Security On Every Level

Operational reliability

Three levels of authorisation checks are employed with DPS: a pin system, a variable longitudinal profi le and a patented cross profi le. Depending upon requirements, one of the following DPS variants is on offer. They differ from each other in the number of bolts and in the style of construction:

• 5+1 bolts, compact construction
• 5+1 bolts, modular construction
• 6+1 bolts, compact construction

A compact construction means that the cylinder lengths cannot be altered at a later date. In the modular construction, the cylinder lengths can be determined individually

DPS- Time-Tested Technology

The mechanical locking system DPS (Double Profile System) is justifi ably one of EVVAs most popular mechanical cylinder locking systems. The DPS technology refl ects decades of experience and meets all basic demands of modern security technology. Essential cylinder lock security is ensured by means of a triple authorisation check.

Wear and tear resistance

With its special thickness of material, the EVVAlongitudinal profi le offers a high resistanceto wear and tear. The DPS serrated profi leconstruction results in a smooth key insertionand, together with the springless locking barprofi le, ensures low abrasion of the key and along lifespan of the cylinder. Furthermore, theprofi le allows for the necessary differentiationof the key in a locking system.

Combinations

This combination of longitudinal profi le,pin system and cross scanning allows therealisation of manifold entry authorisationwishes for the locking system.

For the protection against key duplication,illegal copies ("black keys") and key manipulation,the system has three different safeguardsat its disposal each complementingthe other in their effectiveness.

Organisational protection

Keys are only manufactured for authorisedindividuals with the appropriate proof oflegitimacy (e.g. security card).

Legal protection

DPS keys may only be manufactured exclusivelyby EVVA and by specialist companiesautho rised by EVVA. The DPS locking systemfeatures a patent protection on the cross profi le.In this way, it is possible for EVVA to take legalaction against the unauthorised commercialmanufacturing of a duplicate key.

Technical protection

Keys possess technical features, which requirespecial machines and a great deal of expertknow-how. Illegal manufacturing is onlypossible at great expense and, as such, is noteconomically viable.

Cylinder Lock Security

It is a continual race against time to ensure that the new functional principles don’t give illegal opening methods a chance. Thats why only innovative technologies provide a lasting protection against known and future methods of forced entry. All employed technologies have the goal of impeding a break-in.
EVVA develops and integrates protective mechanisms against the following opening methods:

• Detectable opening techniques (the cylinder lock remains fully functional, there are visible traces of tampering): opening with vibrating tools .
• Non-detectable opening techniques: opening with lock tools (e.g. Dietrich).
• Destructive opening techniques (the cylinder lock is destroyed): breaking or ripping the cylinder lock off, drilling into the cylinder, sawing the cylinder off, extracting the core of the cylinder lock

Scanning security

The scanning security takes place in thecompactly constructed cylinder lock viaspecially shaped tumbler pins. In the modularconstruction, the scanning security is providedby the locking pins, which are jointly steeredby a control slide.

Drilling and core extraction security

Hardened steel elements act as standard protectionagainst drilling. By request, the cylindercan also be delivered with increased drillingprotection in the form of carbide elements.

Conformity to Standards

All DPS cylinder locks, in combination with anappropriate protective fi tting, comply withEN 1303:2005 in the locking security category6 and the lock picking resistance category 2(high standard). They are suitable standardlocks for fi re and smoke doors EI 30 and E 30
