Overview

Honeywell's Fast-Acting, Two-Position Actuators are line volt (230V), 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 N•m) 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
  • 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 Underwriter’s Laboratories Inc. UL555S ratings up to 350 F
  • Models available with SPST position-indicating switches (7 degree, 85 degree stroke)
