SMAY installed a fire-prevention system in the 2-story underground garage owned by Hotel Bania in Białka Tatrzańska and secured one of the staircases which led from the ground level to the garage using the iSWAY-WFC system. The works included installation of two ZUP supply units on the -2 level and 10 jet fans along with CO/LPG detection units and a complete system wiring. Furthermore, SMAY commissioned and calibrated the system, and then performed the hot marker smoke tests. Our devices of the iSWAY series offer comprehensive solutions for overpressure protection against smoke ingress into the escape routes of buildings in case of fire. Thanks to their compact design and a wide selection of versions, the solution can be installed practically anywhere within the facility, while the varied performance of fans ensures the required level of pressure gradation and maintains the air discharge rates from the protected areas in compliance with the standards.
