LPS 1175 Terra Diamond Turnstile

Following Frontier Pitts Ltd achievement of becoming the first company to achieve LPS 1175 Issue 6 for the full height Terra Diamond Grade 3 and Grade 4, 34 Terra Diamond Turnstiles have been installed on a high security site in Europe.To achieve the LPS 1175: Issue 6 standard, the Terra Diamond Turnstile successfully resisted an intensive attack test programme. This involved a series of attack tests each lasting at least 10 minutes using a wide array of hand tools and battery powered tools.

The Terra Diamond turnstiles are the only turnstiles currently on the market that are approved to LPS 1175 Security Ratings 3 and 4.

Sally Osmond, Brand Development Manager commented: Our client approached us with a very specific requirement for multiply LPS1175 Pedestrian Control systems. We worked closely with our customer and LPCB to achieve the standard, then fulfilled and exceed the projects specifications and expectations.

Solution:
Forsmark Nuclear Power Plant is one of the largest power plants in Sweden, situated on the east coast, in the province of Uppland. Forsmark has three boiling water reactors that generation rate 20-25 billion kilowatt-hours of electricity in a normal year. This is approximately one-sixth of Sweden’s total electrical energy consumption. The intention was to protect the power plant from unauthorised trespassing. The Turnstiles are used to provide access and authorisation to various zones within the power plant.The Turnstiles were operated using a Biometric reader system for entry and a card reader system to exit the protected area. The Turnstile were installed with positioning devices (switch) with relay contacts acting as an alarm that were interconnected to the local intrusion alarm system. The Turnstile finish was also required to conform to the environmental conditions at the power plant and to the Swedish Law and Regulations as well as European standards such as the Low Voltage Directive and the EMC Directive. Programmable requirements for the PLC were required to fulfil ISO 9000-3.

British Standards Regulations
The Terra Diamond Turnstile was specified as it is a rugged, heavy duty turnstile which complied with SS-ENV 1627 MK4 and British ”Loss Prevention Standard”, LPS 1175 issue 6, class 6, can be used if it complies with requirements of SS-ENV 1627 MK4.
