The Honeywell Fast-Acting, Two-Position Actuators are 24 V, 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.
Honeywell 175 lb-in. (20Nm) torque, spring return, direct-coupled, 24 Vac actuator accepts two-position (SPST) control with an integral junction box. Reliably operates in smoke control systems requiring UL555S ratings up to 350F.
