Fast-Acting, Two-Position Actuators ,spring return for Fire & Smoke dampers

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.

The MS4120F, MS4620F, and MS8120F DCA are designed to operate reliably in smoke control systems requiring Underwriters Laboratories Inc. UL555S ratings up to 176 º C or 350°F. Order mounting bracket separately model 205649.

Fire & Smoke Spring Return Actuators
*Model Number*	*Input Signal*	*Supply*	*Torque*	*Stroke Time Sec*
MS4620F1005	On/off switch 230 VAC	230 VAC	20 NM	15 sec spring return
MS8120F1002	On/off switch 24 VAC	24 VAC	20 NM	15 sec spring return

          SmartAct damper actuators
Honeywell, with feed back from the customer, has securely developed the SmartAct actuator combining, with future oriented technology, all of the technological advantages found in the DCA market place. Just to mention a few: self-centring hub adapter, detachable wiring box, rotation direction switch, adjustable mechanical end-stops, and many others.
