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.
