Honeywell MS4104F1010 is a Spring Return 2-Position Control Direct-Coupled Actuator designed for used with Fire and Smoke dampers (on/off control). This actuator has a line voltage of 120V and 30 lb-in. (3.4 N•m) minimum driving torque.

The Honeywell MS4104 Fast Acting Two-Position Actuators function is to accept an on/off signal from a single-pole, single-throw (SPST) controller. Reversible mounting of the actuator allows either clockwise (CW) or counterclockwise (CCW) spring rotation.

• 30 lb-in. (3.4 N•m)  minimum driving torque at 350 F (176 C)
• Silent operation during the holding
• 95-degree rotation angle
• Housing Die-Cast Material
• Holds rated torque at a reduced power level
• Reversible mounting facilitates use in either clockwise (CW) or counterclockwise (CCW) spring rotation
• Integral spring return ensures the level of return torque
• Fifteen-second spring return timing
• No special cycling required during long-term holding
