​The Belimo FSLF120 Fire and smoke damper actuator operates HVAC systems to regulate building fire and smoke spread. This product operates at 120V AC voltage to generate 30 in-lb torque through its spring return fail-safe system. A power failure triggers the actuator to move dampers into their default position which ensures safety. The on/off control type makes it easy to integrate this device into fire and smoke control systems. The system provides improved building security alongside fire safety standard compliance along with dependable operation under critical circumstances.
The Belimo FSLF120 Fire/Smoke 120V;35#;S/R;On/Off is a critical component that ensures safety and compliance in HVAC systems, especially in fire and smoke control applications. This motor, which operates at 120 volts and can withstand pressures of up to 35 pounds, is designed to provide dependable performance in harsh environments. It has a spring return (S/R) mechanism and an on/off control mode, making it ideal for use in fire and smoke damper systems where rapid and fail-safe operation is required. The Belimo FSLF120 actuator quickly closes dampers to prevent the spread of smoke and fire throughout a building, thereby protecting occupants and limiting property damage. Its spring return mechanism ensures that the dampers close accordingly even in the absence of power, increasing safety.
Fire and Smoke Control: This actuator is specifically designed for fire and smoke damper applications, ensuring a prompt and reliable response in critical situations and preventing the spread of fire and smoke throughout a building.
120V Power Supply: Operating on a 120-volt power supply, the actuator is compatible with standard electrical systems, simplifying installation and integration into existing fire and smoke control setups.
High Pressure Rating: Capable of withstanding pressures of up to 35 pounds, the actuator provides robust performance, ensuring effective operation even in high-pressure environments commonly found in fire and smoke damper systems.
Spring Return Mechanism (S/R): Featuring a spring return mechanism, the actuator automatically returns to a predefined position when power is interrupted, ensuring fail-safe operation and compliance with safety regulations.
Signs of a Faulty Belimo FSLF120 Fire/Smoke 120V;35#;S/R;On/Off:
Failure to Activate: If the actuator does not respond when triggered by the fire alarm system or smoke detectors, it may indicate a malfunction in the actuator's internal components or electrical connections.
Inconsistent Operation: Erratic behavior, such as intermittent activation or failure to return to the default position after power loss, suggests potential issues with the actuator's mechanical or electrical components.
Unusual Noises: Grinding, clicking, or buzzing noises during operation could indicate mechanical issues with the actuator, such as worn gears or damaged components.
Limited Movement: Difficulty in moving the actuator or a reduced range of motion compared to normal operation may signal mechanical obstructions, binding, or internal damage.
