A robust and performance fully integrated fire detection and fire suppression system.

FOGTEC 5000 series brings together the cutting-edge solutions of the newest developments in fire detection and monitoring product in line with the latest rail-specific developments for FOGTEC firefighting systems. The fire detection and monitoring system is modular bus-based with a layout which allows a lean and simple system design for every type of vehicle. The system architecture can be used for so-called SIL-systems or for systems without such requirements. The center units (CPU) provide a continuous monitoring of each single component with a detailed diagnostic program and communicate with the TCMS by using data-interface as Ethernet, TRDP, CAN, RS 485 or MVB. The addressable detectors are available as smoke, temperature, CO, CO2 or multi-criteria detectors. Busbased single and multiple I/O modules allow decentralized distributed control and monitoring of extinguishing units, digital sensors and actuators as well as interface with external sub- systems or with the TCMS. A stabilized power supply module ensures system compatibility with train power supply. All components are available for basic integrity levels as well as safety integrity levels up to SIL 2. The software development and documentation follows the latest European standards as EN 50657.

Continuous product development for the best firefighting solutions.

FOGTEC 5000 series covers also a wide portfolio of firefighting solutions for every need. The worldwide established FOGTEC high pressure water mist technology, nitrogen-gas-systems and aerosol extinguishing systems are specifically developed for rail applications. The systems are approved for safety integrity level solution and tested in accordance to ARGE as well as UNI-standards with full assessment. A new nitrogen release concept made a significant reduction of water and nitrogen quantities possible, whilst maintaining the performance and with great benefits to weight and space management.

New innovative valves have been adopted for enhanced pressure control, diagnostics and high reliable system activations. Multiple-cylinders modules are now available with redundant activation in order to target the highest RAMS values. Cylinder systems are in accordance to EN and DOT standards, complete modules get a CE-mark. System components and architecture are also designed to be certified up to SIL-2 according to latest standards. All this in order to set a new benchmark of highest performance, quality and safety.
