FLLV, Adjustable Fusible Link Louvers

Adjustable Fusible Link Louvers are recommended for use in rooms where ventilation is needed and at the same time
isolating the room whenever fire is present. When louver is exposed to heat at 165°F, the fusible link trips and the spring
loaded louver blades shut to form an air tight fire and smoke seal.
WHI Listing Mark with a 90 Minute Fire Rating is stamped on the frame of the louvers.
Installation is easy. No need to drill holes for fasteners. All screws are mounted
on the room side leaving the corridor side free of fasteners for security purposes.
Fuses are replaceable.
