27 SecuriRAS ASD 535 aspirating smoke detectors are used for protecting the equipment rooms, control rooms, cable tunnels and the main building at the Longyang Gorge hydropower station. They use the most efficient aspirating fan unit currently available on the market, which allows larger sites to be protected compared to previous systems.
