Description
MS4620F1005NM/U Honeywell Damper Actuator, The MS4604, MS4609, MS8104, MS8109 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, single-throw (spst) controller. Reversible mounting allows actuator to be used for either clockwise (cw) or counterclockwise
(ccw) spring return and are designed to operate reliably in smoke control systems.
FEATURES
• Reversible mounting facilitates use in either clockwise
(cw) or counterclockwise (ccw) spring rotation.
• No special cycling required during long-term holding.
• Integral spring return ensures level of return torque.
• Stainless steel internal spring.
• Fifteen-second spring return timing.
• No audible noise during holding.
• Patent pending design eliminates need for limit switches
to reduce power consumption.
• Models available for 24 and 230 Vac.
• Ninety-five degree angle of rotation.
• Actuator holds rated torque at reduced power level.
• Housing design allows flush mounting to damper.
• Self-centering shaft adapter (SCSA), patent pending.
• Designed to operate reliably in smoke control systems.
