Fast-Acting, Two-Position Actuators
FOR FIRE/SMOKE CONTROL APPLICATIONS
The MS4209F, MS4309F, MS4709F, MS4809F, MS8209F,
MS8309F 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.
Models are available with clockwise (cw) or counterclockwise
(ccw) spring return and are designed to operate reliably in
smoke control systems requiring Underwriter's Laboratories
Inc. UL555S ratings up to 350°F.

FEATURES
• 80 lb-in. (9 N•m) minimum driving torque
at 350°F (176°C).
• Integral spring return ensures level of return torque.
• Stainless steel internal spring.
• 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.
• 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.
Humidity Rating:
! 5% to 95% RH noncondensing.
IMPORTANT
• The actuator is designed to meet UL555S standards
at 350°F (176°C). The actuator must be tested with
the damper to achieve this rating.
• Honeywell does not recommend using linkages with
these actuators because side-loading of the output
hub reduces actuator life.
Stroke:
! 95° ± 3°, mechanically limited.
Torque Rating (at Rated Voltage):
! Typical Holding (0°F to 350°F): 80 lb-in. (9 N•m).
! Typical Driving (0°F to 350°F): 80 lb-in. (9 N•m).
! Spring Return: 80 lb-in. (9 N•m).
! Stall Maximum: 240 lb-in. (27 N•m).
Noise Ratings (Maximum):
! Driving Open: 80 dBA at 1m.
! Holding: 20 dBA at 1m (no audible noise).
Timing (at Rated Torque and Voltage):
! Drive Open:
! Ambient Conditions: 25 sec maximum, 14 sec typical.
! At 350°F: 75 sec maximum.
! Spring Close: 20 sec maximum.
Design Life (at Rated Voltage):
! 60,000 full stroke cycles.
Minimum Damper Shaft Length:
! 1-1/2 in. (38 mm).
