Description

MS8120F1200 Honeywell Damper Actuator , The MS4120F, MS4620F, MS8120F, S2024-F, andS20230-F Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) for on/off damper control.

The actuator accepts an on/off signal from a single-pole, single-throw (spst) controller.

Reversible mounting allows actuator to be used for either clockwise (cw) or counterclockwise (ccw) spring rotation.

Designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc. UL555S ratings up to 350°F, if applicable.
