• Robust construction –  to survive the most demanding environments
  • Multiple energy sources – can be controlled in sequence to remove integration requirements between different technologies
  • No programmable Logic – controls operations in sequence to reduce the need for programmable logic
  • Eliminates electrical wiring – to access points reducing cost of cabling & installation
  • 3rd party approved – to PLe for applications requiring high reliability
  • Special purpose units can be designed to provide solutions for specific needs

 

Contact us and we can help define your trapped key interlock system.

At Fortress we will always look to assist with project delivery and efficiency by supporting on the design of trapped key interlock systems. Our team can be on hand to survey equipment on site, interpret system drawings or discuss concepts early on in project design.

The advantage of trapped key systems is that any number of power sources can be interlocked into any number of access points. Determining part numbers and a bill of materials may initially appear complex but a Fortress representative can assist with this and provide engineering drawings of each component.

Using key engravings and colour coding will also make sequences easy to understand and simple to follow. With 30 characters of text and 9 colours available we can define a coding system for you and record all keys supplied so every key supplied is unique.

Using end user information and project documentation we can coordinate across multiple integrators and equipment suppliers.

What is Trapped Key Interlocking?

Trapped Key Interlocking   Put simply, Trapped Key Interlocking uses mechanical devices to keep operators safe by holding guards closed until it is safe to enter the area. The simplest way of achieving this is with a key switch and a door module with one key. The key is trapped in the switch while it… Continue reading What is Trapped Key Interlocking?
