MS8109 Fast-Acting, Two-Position Actuators
FOR FIRE/SMOKE CONTROL APPLICATIONS
PRODUCT DATA
FEATURES
• 30 lb-in. (3.4 N•m) or 80 lb-in. (9 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.
(See Operation section.)
• 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.
APPLICATION
The MS4104, MS4109, MS4604, MS4609, MS8104 and
MS8109 Fast-Acting, Two-Position Actuators are 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.
• 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°, 85° stroke).

IMPORTANT
Honeywell does not recommend using linkages with
these actuators because side-loading of the output
hub reduces actuator life.
Temperature Ratings:
Ambient: 0°F to 130°F (-18°C to 55°C).
Shipping and Storage: -40°F to 140°F (-40°C to 60°C).
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.
Humidity Ratings: 5% to 95% RH noncondensing.
Noise Rating (Maximum):
Driving Open: 75 dBA at 1m.
Holding: 20 dBA at 1m (no audible noise).
Controller Type:
MS4104, MS4109: Line voltage (120 Vac),
two-position, SPST (Series 40).
MS4604, MS4609: Line voltage (230 Vac),
two-position, SPST (Series 40).
MS8104, MS8109: Low voltage (24 Vac),
two-position, SPST (Series 80).
Minimum Damper Shaft Length: 2 in. (51 mm).
Device Weight: 5 lb (2.3 kg).
Stroke: 95° ± 3°, mechanically limited.
Electrical Ratings: See Table 2.

Honeywell recommends following all local, state and national
codes for periodic testing of the entire smoke control system. Refer to National Fire Protection Association (NFPA)
National Fire Codes®: NFPA90A, NFPA92A and NFPA92B
for your application.
NFPA recommends periodic examination of each fire/smoke
damper (semi-annually or annually) to ensure proper performance.
Design Life (at Rated Voltage): 30,000 full stroke cycles.
