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.
