Resideo Braukmann ms4104f1010/u Fire and Smoke Damper Actuator On/off Spring Return 30 In-lb 120V Ac Hardwired Nema 1 IP40

Product Description

The Resideo Braukmann MS4104F1010/U is a fire and smoke damper actuator built for critical life-safety applications in commercial and institutional buildings. This actuator delivers reliable on/off control with spring return fail-safe action, meaning it automatically returns to its safe position if power is lost. That fail-safe behavior is essential during a fire event, when dampers must close quickly to block the spread of smoke and flame through ductwork and air handling systems. The MS4104F1010/U is rated for both fire and smoke damper applications, making it a dual-rated solution that meets demanding code requirements in a single unit. It operates on 120V AC power and draws 18 watts during normal operation. The actuator produces a rated torque of 30 inch-pounds, which is sufficient for direct-mount installation on round shafts measuring 1/2 inch in diameter. Shaft rotation covers a clockwise and counterclockwise stroke of 95 degrees. In an emergency, the spring return mechanism closes the damper in 15 seconds or less, helping limit fire and smoke travel through a building. The unit is hardwired and features a single-pole double-throw auxiliary contact for integration with fire alarm panels and building automation systems. With a NEMA 1 and IP40 enclosure rating, the actuator is suited for indoor dry locations typical of HVAC mechanical rooms and air handling unit installations. Operating temperature range spans from 0 degrees Fahrenheit to 130 degrees Fahrenheit. The overall dimensions are 9 inches in height, 5.125 inches in width, and 3.25 inches in depth. HVAC technicians and fire protection contractors rely on actuators like the MS4104F1010/U for retrofit and new construction damper control projects where code-compliant, rapid-response operation is required.

• Dual-rated for both fire and smoke damper control applications
• Spring return fail-safe action closes damper within 15 seconds on power loss
• SPDT auxiliary switch enables integration with fire alarm panels and building automation systems
