Fast-Acting, Two-Position Actuators

APPLICATION

The MS4120F, MS4620F, MS8120F, S2024-F, and S20230-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.
