EVVA EPS high-security system offers a cost-effective way to implement a complex and restricted master key system.
EPS employs unique, patented features to harden it against lockpicking, drilling and key bumping, as well as making key theft and illicit duplication more difficult. At the front of the cylinder more hardened steel pins provide additional intrusion-resistance.
In addition, multiple broaching sidebars (providing a theoretical 133 million combinations) enable us to develop and install large multi-tiered hierarchies of thousands of locks with a very low probability of phantom keys. All cylinders are made from brass, stainless steel and nickel components to deliver maximum operational lifespan.
EXCEPTIONAL MASTER KEY HIERARCHIES
Each key has several side cuts with matching notches to the key’s side cuts. Cylinders contain a key sidebar with matching notches. When a user inserts the correct key, the sidebars cut in the key line up with those etched into the sidebar in the cylinder. This allows key rotation and the lock to open.
Each master key has its own unique set of access permissions: some allow office managers unrestricted access to their particular section (but nowhere else); some are for contract cleaners restricted to specific areas; others are for security guards with very broad access requirements.
An EPS system enables Independent Locksmiths & Security, as an authorised EVVA dealer, to make specific master keys that meet any of these requirements — whether a user needs access to just three locks within the system, or as many as three thousand. Critically, the patented design and keying algorithms that drive the security of the EPS minimise phantom key risk in even these large and complex security systems. Normal master key systems cannot adequately handle this sort of hierarchical complexity. As the system scales, the possibility of phantom keys occurring rapidly becomes unacceptably large.
