Honeywell MS4104F1210 Actuator
The Honeywell MS4104F1210 is a high-performance Fast Acting Actuator engineered specifically for fire and smoke applications. This 120 Vac spring return actuator delivers 30 lb-in of torque, ensuring reliable fail-safe operation in critical life safety systems. Designed for precise two-position control, it handles UL555 and UL555S requirements for leakage and fire ratings. This model features a 95-degree stroke and is compatible with a 1/2-inch round shaft, housed in a durable NEMA 1 enclosure. It includes two internal auxiliary switches (SPST) for position feedback, streamlining field wiring for contractors. Whether you are searching for Honeywell MS4104F1210 focus specs or an MS4104F1210/U replacement, this unit provides the identical footprint and performance. Its robust design minimizes maintenance callbacks in demanding HVAC environments while ensuring rapid response during emergency smoke control sequences.
Key Benefits for Technicians
- Rapid Response: Under 15-second drive time at rated voltage ensures immediate fire and smoke damper closure.
- Simplified Integration: Direct-coupled mounting for 1/2" shafts eliminates the need for complex linkages.
- Durable Construction: Die-cast aluminum housing provides superior protection in mechanical rooms.
- Integral Feedback: Built-in SPST auxiliary switches allow for easy monitoring of open/closed status.
- Fail-Safe Certainty: Mechanical spring return provides 100% reliable closure during power loss.
Common Questions
Can the MS4104F1210 be used for modulating control?
No, this is a two-position actuator designed for on/off service in fire and smoke safety systems.
Is the MS4104F1210 interchangeable with the MS4104F1210/U?
Yes, the "/U" suffix simply denotes a universal packaging designation; the technical specifications and performance are identical.
What is the torque rating for this actuator?
This model delivers 30 lb-in torque, suitable for smaller dampers and specific UL-rated smoke leakage applications.
