Honeywell Universal Fire and Smoke Damper Actuator (80 lb-in)

The Honeywell MS4109 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. Features: 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. 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...
