Active Compensated Stairwell Pressurization System
Advanced Active Compensated Stairwell Pressurization System
The ACSP Active Compensated Stairwell Pressurization System from LFSystems changes how you control stairwell pressure. The L864 is designed to maintain a positive pressure in a high-rise building stairwell in the event of a fire. The L864 compares pressures in multiple zones and controls a listed stairwell pressurization fan as well as a relief damper to maintain the user determined range. The ACSP is designed to handle up to 12 floors on a single controller.
The Advanced ACSP adds the use of Injection Point Regulators and Dampers to provide the most balanced stairwell pressurization system in the industry. As doors open and close, the L850 and modulating Injection Point Dampers maintain the proper pressure in each “zone” of the stairwell. This ensures the entire stairwell is safe and clear for evacuation.
