LFSystems recently launched the first-ever UL 864/UUKL-listed, factory-built stairwell pressurization control systems. LFSystems’ Active Compensated Stairwell Pressurization Systems (ACSP) can be used with any manufacturer's fan as long as the motor is inverter duty. The fan’s VFD would be supplied and factory-programmed by LFSystems for the specified motors. There are two systems, Standard and Advanced, to ensure your building’s design is covered.
The Standard and Advanced ACSP will meet or exceed your project’s bid documents.
ACSP Features & Benefits
Specifically designed and programmed for stairwell pressurization control
Built-in redundancy with multiple transducers
Circuit integrity monitoring between FSCS and controller; if there is a fault (ground/open/short) in the wiring the L864 will autostart
Packaged system; not piecemealed
Listed to UL 864/UUKL per NFPA 92; eliminates the need for on-site listing
High value, cost-effective, factory-built solution
