A typical MSVS system is located within a protected lobby and is attached to a rising smoke shaft or fire-rated ductwork system with a fan set at the shaft’s head.
Systems often allow extended travel distances within the lobby and generally consist of a rooftop fan set and a series of smoke dampers and grille sets that provide a free area of 0.6m2 (the smoke shaft/ducting itself also having a footprint of 0.6m2). Zone control units are networked and include fire officer over-ride switches and smoke detectors (or an interface connection from the landlord’s fire alarm system).
In some cases, pressure sensing is also utilised to reduce fans speed during means of escape mode and to allow occupants to escape without the exit doors being difficult to open.
