Invensys Recalls Siebe Actuators in Building Fire and Smoke Dampers

Invensys is recalling Siebe actuators used in building fire and smoke dampers because they can jam and prevent dampers from closing during a fire.

What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The source text explicitly states that if dampers fail to close during a fire, serious injury or death can be suffered by building occupants, which aligns with the rubric criteria for Severe severity involving significant injury or death reports.

Plain-English summary

Invensys Building Systems is recalling up to 560,000 Siebe actuators, specifically MA-200 and MA-200-1 series models, used in building fire and smoke dampers. These actuators were installed by private contractors in commercial and residential buildings between December 1993 and October 1999. The actuators have manufacture date codes ranging from 9348 through 9947.

The recall is due to a defect where the actuators can jam, preventing the dampers from closing during a fire. The dampers are designed to close to limit the spread of smoke, fire, and fumes through a building's ventilation system. If the dampers fail to close, building occupants may suffer serious injury or death. Building owners, damper manufacturers, and fire and safety investigators have reported instances of dampers not closing during testing.

Building owners and managers should immediately contact Invensys' Program Coordination Office at (877) 481-2372 between 7 a.m. and 7 p.m. CT, Monday through Friday. To be eligible for a free actuator replacement, the building owner must test the actuator and report the results to Invensys; only actuators that fail testing will be replaced.
