Secure patented key control at Dartmoor Zoo

News | 26. November 2025.

Dartmoor Zoo, a non-profit zoo in Devon, is dedicated to species conservation, education and research. The EPS mechanical locking system (2nd generation) now offers secure and efficient access control to sensitive areas, especially to fences with potentially dangerous animal zones.

Set in 33 hectares of woodland on the edge of Dartmoor National Park, the zoo is home to an impressive variety of exotic and native animals, including Amur tigers, African lions and Amur leopards.

On-site challenges before the introduction of the new patented master key system

Before implementing the new master key system, the zoo faced the challenge of ensuring secure and efficient access control to sensitive areas, particularly enclosures with potentially dangerous animals. The previous master key systems were outdated and did not provide the necessary security and flexibility required for the zoo's daily operations.

Installation of EPS NP (2^nd generation) and its advantages

The EVVA EPS NP system (2^nd generation) was installed in collaboration with local partner Sir Fix-a-Lock. This system offers robust patent protection, long-term key control and high reliability in demanding environments. A total of 192 Asec weatherproof padlocks were installed in a 6-level master key system. The flexibility of EPS NP enabled graduated key control across the entire site, including special levels for animal care.

Advantages of the new patented key system for the zoo

Thanks to the new master key system, the zoo has been able to implement a secure and practical solution that enables staff to work efficiently while maintaining strict access controls. The colour-coded keys make it easy to quickly identify access authorisations, which is particularly advantageous in security-critical areas. The Asec weatherproof padlocks also offer high resistance to environmental influences, ensuring the longevity of the system.

‘EPS has revolutionised our access control and gives us the security and flexibility we need.’

The project at Dartmoor Zoo impressively demonstrates how EVVA's flexible master key systems can be adapted to specific requirements to ensure security, control and long-term protection.
