APPLICATION
The MS4104, MS4109, MS4604, MS4609, MS8104,
MS8109 Fast-Acting, Two-Position Actuators are spring
return direct coupled actuators (DCA) with an integral
junction box 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 return and are designed to operate reliably in
smoke control systems requiring Underwriter’s
Laboratories Inc. UL555S ratings up to 350°F if
applicable.
