The Belimo FSLF24 is a spring return fire/smoke damper actuator designed for fail-safe operation in critical HVAC safety applications. This 24-volt actuator provides reliable two-position control with 35 pound-inches of torque, making it suitable for small to medium-sized fire and smoke dampers in commercial HVAC systems.

Key Features:

• 24VAC/DC voltage operation for versatile installation
• 35 lb-in (4 Nm) torque output for positive damper closure
• Spring return mechanism ensures fail-safe positioning during power loss
• Two-position on/off control for fire/smoke damper applications
• Designed for UL 555S listed fire/smoke dampers
• Compact housing for easy mounting in tight spaces
• Direct mounting capability for quick installation

This actuator is specifically engineered for life safety applications where reliable damper closure is critical during fire or smoke events. The spring return function automatically closes the damper when power is removed, meeting fire code requirements for smoke control systems. Ideal for commercial buildings, hospitals, schools, and other facilities requiring code-compliant fire/smoke damper control.
