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.
