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.
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.
