Learn about stairwell pressurization systems, design options and details as well as code references and compliance.
The all-new L864 is a completely packaged, pre-programmed pressure-based control system listed to UL864 designed to maintain a positive pressure in a high rise stairwell, elevator shaft or multi-zoned area in the event of a fire. With the introduction of the Active Compensated Stairwell Pressurization (ACSP) and the first of it's kind, Advanced ACSP Systems, LFSystems has changed how stairwell fans are controlled.
1:37 - - No pressurization in the stairwell. - - 2:12 - - smoke got into the stairwells, inside seismic joints, elevator hoist-ways, into air-conditioning systems on the roof, it was recycled back into shafts + corridors, up plumbing chases + bathroom vents.
