The MS4104, MS4109, MS4604, MS4609, MS8104 and MS8109 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 counterclockwise (ccw) spring rotation.
Features & Benefits:- 30 lb-in. (3.4 Nm) or 80 lb-in. (9 Nm) minimum driving torque at 350°F (176°C)
- Reversible mounting facilitates use in either clockwise (cw) or counterclockwise (ccw) spring rotation
- Integral spring return ensures level of return torque
- Fifteen-second spring return timing
- 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
- Die-cast aluminum housing
- Housing design allows flush mounting to damper
- Models available with SPST position-indicating switches (7°, 85° stroke).
- Designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc UL555S ratings up to 350°F
- Non-UL marked models available
