6. Operating Instructions

The Belimo FSLF24-S US actuator is designed for automatic operation in conjunction with a fire alarm or building management system. It typically operates in a fail-safe mode, meaning it will drive the damper to a safe position (e.g., closed) upon loss of power.

6.1 Initial Power-Up

1. After completing all electrical connections and mounting, restore power to the actuator.
2. Observe the actuator's initial movement. It should drive the damper to its default position (e.g., open or closed, depending on configuration).
3. Verify that the damper moves smoothly and without obstruction.

6.2 Functional Testing

Regular functional testing is crucial for fire and smoke dampers. Consult local fire safety regulations for required testing intervals.

• Initiate a test sequence from your building management system or fire alarm panel to activate the damper.
• Confirm that the actuator drives the damper to its intended fire/smoke safety position.
• Verify that the damper returns to its normal operating position once the test signal is removed.

7. Maintenance

The Belimo FSLF24-S US actuator is designed for long-term, reliable operation with minimal maintenance. However, periodic inspection is recommended.

• Annual Inspection: Visually inspect the actuator and its connections for any signs of wear, damage, or corrosion.
• Functional Check: Perform a functional test of the damper and actuator as per local regulations (e.g., NFPA 80, NFPA 105).
• Cleaning: Keep the actuator free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• No Lubrication Required: The actuator is factory-lubricated and does not require additional lubrication.
