Commercial Building Controls : Dampers and Damper Actuators : Fire and Smoke Damper Actuators : 120 Vac Fire/Smoke Actuators : 30 lb-in. 120V : MS4104F1010/U
Fast-acting, two-position actuator with 30 lb-in., spring return
Overview
Honeywell's Fast-Acting, Two-Position Actuators are line volt (120V), 30 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
- 30 lb-in. (3.4 Nm) or 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 to damper
- Designed to operate reliably in smoke control systems requiring Underwriters Laboratories Inc. UL555S ratings up to 350 F.
- Models available with SPST position-indicating switches (7 degree, 85 degree stroke).
