Honeywell MS4120F1006 Damper Actuator

Honeywell MS4120F1006 Damper Actuator. 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 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 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 degree, 85 degree stroke)
