FIRE PREVENTION FOR CABLE LINER SHEREMETYEVO MONORAIL
Safe transport between terminals at Moscow’s largest airport in the people mover
The Sheremetyevo International airport in Moscow is the largest in the metropolis of millions and all of Russia. It is made up of two separate terminal areas to the north and south of the take-off and landing runways. Since May 2018, these two building complexes have been connected with a fully automatic people mover from the Austrian manufacturer Doppelmayr Cable Car GmbH. To ensure that passengers reach their destination safely, WAGNER Rail has provided technology for effective fire prevention in the passenger areas and technology containers of the cable liners.
The Doppelmayr Group, known all over the world from the field of ropeway engineering, is also active in the automated people mover sector with its subsidiary Doppelmayr Cable Car. This type of train covers many applications: airports, city centres, amusement parks, metro/underground systems and more. But this is the first time the Doppelmayr cable liner has been used in Russia. What’s special about the project? In contrast to established people movers, which run above ground like the one at the airport in Frankfurt, the cable car track has been constructed underground in a tunnel under the airport. The building work took place while the airport was still in operation.
To ensure that operation is as smooth and free from interruptions as possible and to minimize the damage caused if a fire breaks out, the fire prevention experts at WAGNER Rail GmbH offered an integrated solution that combines different technologies: multi-sensor fire detectors, linear heat detectors and an aerosol extinguishing system all connected to a fire detection control panel.
In the four passenger areas per cable liner, WAGNER Rail GmbH has implemented multi-sensor fire detectors. Multi-sensor fire detectors work on the principle of light scattering. At the heart of the technology is a high-quality opto-electronic measuring chamber, which optimally recognises light and dark smoke particles. These sensors enable a fire to be detected reliably and passengers to be evacuated as quickly as possible. This is particularly important, as the cable liner runs in a tunnel system.
The technology areas have been equipped with a separate fire detection solution: Each carriage contains three technology containers. These contain the manifolds and control units. The technology containers are all equipped with multi-sensor fire detectors and linear heat detectors. The heat sensor is responsible for temperature monitoring. In the event of a fire, it reacts by causing a short circuit in the sensor line if the alarm temperature is exceeded. The detected parameter results in an alarm signal.
To ensure that fires in the technology areas can be extinguished effectively in the early stages in an emergency, an aerosol extinguishing system was also integrated into the fire prevention solution. This is used in all technology areas in all carriages.
