Description for Honeywell MS4309F1005

Spring return direct coupled actuators (DCA) for on/off damper control with an integral junction box. The actuator accepts an on/off signal from a single-pole, single-throw (SPST) controller. They are designed to operate reliably in smoke control systems requiring Underwriter's Laboratories Inc. UL555S ratings up to 350 F.

Features

  • 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.
  • Models available for 24, 120, and 230 Vac.
  • Ninety-five degree angle of rotation for tight damper closure.
  • Actuator holds rated torque at reduced power level.
  • Die-cast aluminum housing. Housing design allows flush mounting to damper.
  • Integral junction box with three conduit openings eliminates need for separate wiring box.
  • High-temperature indicator included.
