Early Warning Fire Detection in underground stations

Ranging from airports and seaports, to train stations and mass rapid transport systems (MRT), to buses and coaches and their stations and to maintenance facilities, the key objective for operators in the transport industry is safety for passengers and goods. MRT takes place largely underground. Stations, as well as tubes, are confined spaces with limited escape capabilities. In case of a fire incident, thousands of travellers will be trapped, hard to reach and are likely to panic. An Early Warning Fire Detection System, supporting multiple alarm thresholds, each one linked to a tested and maintained response scenario performed by regularly trained intervention forces, will help the underground operator to keep control. Professionally planned and implemented, an Early Warning Fire Detection System will avoid fatalities, reduce loss and speed up recovery. It also contributes to a positive image of the MRT, thus improving its acceptance and usage

Causes of fires in MRT stations

• Smoking, in particular in combination with a littering problem on the tracks
• Power line failures
• Electrical arcing
• Mechanical failures
• Arson

Challenges for an Early Warning Fire Detection System in MRT stations

• Significant changes in airflow due to the piston effect of trains
• Complex ceiling structures complicate the process of testing and maintenance
• Smouldering fires typically develop over a long period
• Installation of detectors in confined spaces

Key benefits of an Early Warning Fire Detection System in MRT stations

• Business interruption, economic damage and damage to reputation are minimised
• Five warning levels allow for a staged response according fire development
• Split-second, highly sensitive reaction to incipient fires
• Simple handling due to detectors being mounted in easily accessible areas
• Low maintenance requirements, low maintenance frequency and long service life
• Developed in Switzerland, made in Germany
