Product information "Belimo FSLF230-S Fire & Smoke Damper Actuator (230V, 3.5Nm, On/Off)"

The Belimo FSLF230-S is a compact spring-return actuator for fire and smoke damper applications where a low-torque, reliable fail-safe actuator is required. It provides on/off (open/close) control on AC 230 V supply and returns the damper to the safety position automatically on power loss using an internal spring mechanism. The “-S” version includes an auxiliary switch for end-position feedback and interlock logic.

Applications

Fire & smoke damper actuation for small/light dampers
Fail-safe damper control (spring return to safety position on power loss)
End-position feedback/interlock to fire interface or BMS using auxiliary switch
HVAC ventilation safety damper control in risers, small AHUs, and smoke control branches
