Fast-acting, two-position actuator with 30 lb-in., 2 aux. switches, 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
