Honeywell MS4103 manual Fire & Smoke Actuators, Lb-in 3.4 Nm, Lb-in 20 Nm

Fire & Smoke Actuators

Honeywell’s complete line of two-position, fast-acting spring- return actuators meet all of your needs for fire and smoke control applications. All models are designed to meet the UL-555 and UL-555S high temperature requirements for fire dampers and combined fire and smoke dampers.

Safety First

As a life safety system component Honeywell is dedicated to meeting the UL-555 and UL-555S requirements. The elevated temperature test can be performed at the temperature ratings of 250ºF or 350ºF. Honeywell only offers models at 350ºF to meet UL-555 and UL-555S for fire and combined fire and smoke applications to support the highest level of safety for building occupants.

Largest Torque Range in the Industry

Honeywell’s fire and smoke actuators are available in 30, 80 and 175 lb-in with the 175 lb-in being the highest torque commercial fire and smoke actuator available on the market today.

Note: Honeywell's spring return fire and smoke actuators are designed to pass UL-555 and UL-555S 350ºF requirements. They are not designed for HVAC applications. UL-555 and UL-555S requires that all new construction fire and smoke damper jobs have the actuator assembled and tested at the damper manufacturer. A like for like retrofit replacement or technically equal UL-555 and UL-555S approved device is recommended.
