General

Honeywell 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 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. (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.
• Non-UL marked models available.
• Models available with SPST position-indicating switches (7°, 85° stroke).
