MS4104, MS4109, MS4604, MS4609, MS8104,
MS8109 Fast-Acting, Two-Position Actuators
FOR FIRE/SMOKE CONTROL APPLICATIONS
APPLICATION
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
• 30 lb-in. (3.4 N•m) or 80 lb-in. (5.9 N•m) 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.
(See Operation section.)
• No audible noise during holding.
• Patent pending design eliminates need for limit
switches to reduce power consumption.
• Models available for 24, 120, and 230 Vac.
• 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.
• Designed to operate reliably in smoke control systems
requiring Underwriter's Laboratories Inc. UL555S
ratings up to 350°F.
• Models available with SPST position-indicating
switches (7°, 85° stroke).
