Honeywell Fast-Acting, Two-Position Damper Actuator, MS4609F1210-B, 9 Nm, Silver

The MS4609 Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) for Fire and Smoke dampers (on/off 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 counter clockwise (ccw) spring rotation.

• Integral spring return ensures level of return torque
• No special cycling required during long-term holding
• No audible noise during holding
• Patent pending design eliminates need for limit switches to reduce power consumption
• Ninety-five degree angle of rotation
• Actuator holds rated torque at reduced power level
• Housing design allows flush mounting to damper
