MS4104F1210 | FAST-ACTING, 2-POSITION ACTUATOR, 35 LB-IN., 20S D | HONEYWELL

Honeywell MS4104F1210: Fire Protection Actuator The Honeywell MS4104F1210 is a 120V, 30 lb-in fire and smoke actuator designed for reliable operation in fire safety systems. This actuator features two internal switches that provide control functionality. Its compact design and rugged construction make it suitable for use in various industrial and commercial applications. With a torque rating of 30 lb-in, the MS4104F1210 actuator provides ample power for operating dampers, valves, and other control devices in fire protection systems. Its 120V operating voltage allows for direct connection to standard power supplies, simplifying installation and maintenance. The actuator's two internal switches enable independent control of connected devices, providing flexibility in system design. These switches can be used for signaling, interlocks, or other control functions. Our HVAC supply store offers this Honeywell fire and smoke actuator at competitive prices, ensuring you get the best value for your fire protection needs. Their fast shipping ensures timely delivery, minimizing downtime during installation or maintenance.

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.

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.
• Designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc. UL555S ratings up to 350°F.
• Non-UL marked models available.
• Models available with SPST position-indicating switches (7°, 85° stroke).
