The H-2000, H-2024, and H-2230 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, singlethrow
(spst) controller. Models are available with clockwise
(cw) or counterclockwise (ccw) spring return and are designed
to operate reliably in smoke control systems requiring
Underwriter Laboratories Inc. UL555S ratings up to 350°F.
