We offer individual solutions to protect assets and ensure the safety of employees by delivering systems which are tailored to end user requirements. Our open integrated safety systems are scaleable and fit for purpose.

We provide the following systems either on their own or as part of a multiple safety system, which incorporates a combination of different safety solutions.

• Burner Management Systems (BMS)
• Emergency Shutdown (ESD)
• Fire and Gas Detection (F&G)
• High Integrity Pressure Protection (HIPPS)
• Independent Control & Safety Systems (ICSS)

Using emerging technologies and the best product partners we install systems that deliver safety with a flexible approach.

Runback Protection which we designed to prevent a train from rolling backwards, having reached its destination. The design meets the requirements of Safety Integrity Level 2 (SIL2) in accordance with the IEC 61508 standard for functional safety and includes a data logging facility to record when faults and runback conditions occur. Runback has been fitted to underground trains across London.
Selective Door Opening (SDO) and Correct Side Door Enable (CSDE) whereby we have designed and developed in house our Tracklink product to control the opening of train doors in instances where the train is longer than the station platform at which it stops. Our latest version of this, Tracklink III, is based on RFID technology, comprising of a passive beacon (tag), mounted on the platform or on the track sleepers. The system allows maximum use of the platform, automatically selecting the correct amount of doors to be opened , and reducing the time at which the train stops at the station and also improves passenger safety. So far, versions of Tracklink have been adopted by Bombardier, Network Rail and Porterbrook and most recently Tracklink III, by Metronet for the London Underground. In July 2009 Tracklink III was commended at the IET Engineering Innovation Awards - view the certificate here.

Trainborne Trainstop Control was delivered to Nexus, working closely with our product partner Deuta-Werke. The system, based on the European Indusi signalling system works with beacons on the track responding to a red or green signal. The system offered improved diagnostics and a safer method of tuning the electronics to the trainborne magnets and the contract covered 90 Metro vehicles together 3 works locomotives and one tamper.
