Fire and Smoke Protection for Delhi Metro, India

Delhi Metro is a world-class transport system. To ensure reliability and safety, it is equipped with the most modern communication and control systems. The Dehli Metro Rail Corporation (DMRC) demanded the very highest standards for fire safety and smoke control. In addition to the need for the TROX fire and smoke dampers to comply with these requirements, the DMRC specified that the dampers should be subjected to exhaustive factory tests prior to acceptance. These tests included smoke leakage at 250^oC at a pressure of 2.5 kPa, pressure loss test in accordance with AMCA 500, and a cyclic pressure reversal test at 2.5 kPa. All tests were conducted at TROX Malaysia, on dampers selected from the production line by the DMRC. TROX has supplied tunnel fire and smoke dampers for both Delhi Metro Phase 1 and Phase 2 as well as the Delhi Airport Express Line (DAMEL).
