Fire & Smoke Actuators Description
C
The growing sophistication of fire and smoke dampers has introduced an evolutionary shift in damper actuation needs. Belimo’s FSLF, FSNF and FSAF product lines offer a broad assortment of actuators to cover the established range of system applications. To address the expanding use of active smoke control systems, Belimo introduced the proportional FSAF24-SR for stairwell, under-floor and other pressurization applications. Belimo continues to lead market innovation with its newest FSAF24-BAL for consolidating duct balancing applications with fire and smoke actuated dampers.
