Honeywell MS4120F1204 Fast-Acting, Spring-Return, Actuator, Two-Position 175 lb-in., 20 Nm

The Honeywell fast-acting, two-position actuators are line Volt (120V), 80 lb-in., 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.

• 80 lb-in. (5.9 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
