Summary derived from CPSC notice
The following details were not provided by CPSC: UPC codes.
Reason for Recall
As stated by CPSC
Actuators hold open fire and smoke dampers in a building's heating, ventilation and air conditioning (HVAC) system. A spring mechanism integrated with the damper, is designed to close the damper during a fire to limit the spread of smoke, fire and fumes. These MA-200 and MA-200-1 series actuators were used in fire and smoke dampers that were manufactured by various companies from December 1993 through October 1999, which were installed by private contractors in commercial and residential buildings. The actuators have manufacture date codes of 9348 through 9947.
Reported concern (CPSC)
A spring mechanism integrated with the damper, is designed to close the damper during a fire to limit the spread of smoke, fire and fumes. The recalled actuators can jam and prevent the dampers from closing. If dampers fail to close during a fire, serious injury or death can be suffered by building occupants because smoke, fire and fumes can spread through a building's ventilation system.
Recommended Action
Per CPSC guidance
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.
