HONEYWELL MS4609F1010 9NM SR ON/OFF, 230VAC, 50/60HZ, ACTUATOR, SPRING RETURN (US MADE), Certified UL555(FIRED RATED) Related Models MS4104, MS4109, MS4604, MS4609, MS8104, MS8109 FAST-ACTING, TWO-POSITION ACTUATORS APPLICATION The MS4104, MS4109, MS4604, MS4609, MS8104, MS8109 Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) with an integral junction box for on/off damper 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 return and are designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc. UL555S ratings up to 350°F if applicable. FEATURES • 30 lb-in. (3.4 N•m) or 80 lb-in. (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. • Stainless steel internal spring. • 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 operated reliably in smoke control systems requiring Underwriter's Laboratories Inc. UL555S rating up to 350°F. • Non-UL marked version available. • Models available with SPST position-indicating switches (7°, 85° stroke).
