CPSC, Invensys Building Systems Announce Recall of Siebe Actuators in Building Fire/Smoke Dampers

WASHINGTON, D.C. - In cooperation with the U.S. Consumer Product Safety Commission (CPSC), Invensys Building Systems, of Love Park, Ill., is recalling up to 560,000 Siebe actuators for testing and replacement, if necessary, which could be found in fire and smoke dampers. 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. 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

Building owners, damper manufacturers, and fire and safety investigators have reported dampers not closing during testing. The actuators have been identified as IBS or Siebe MA 200 and MA-200-1series with one of the following model numbers: models MA-220, MA-220-0-1, MA-220-0-2, MA-221, MA-221-0-1, MA-221-0-2, MA-223, MA-223-0-1, MA-223-0-2, MA-230, MA 230-0-1, MA-233, MA-233-0-1, MA-240, MA-240-0-1, MA-240-701, MA-240-701-1, MA-243, MA-243-0-1, MA-243-701, MAH-241-0-1, MAH-241-701, and MAH-241-701-1. The Actuators have manufacture date codes of 9348 through 9947. The Actuators were manufactured in the United States.

The MA 200 series Actuators were used in fire/smoke dampers manufactured by the following companies between December 1993 and October 1999:

Building owners and managers whose buildings have dampers containing Invensys/Siebe actuators should immediately contact Invensys' Program Coordination Office at (877) 481-2372 between 7 a.m. and 7 p.m. CT Monday through Friday. A web site where building owners can obtain a complete copy of the program information has been established at To be eligible for a free actuator replacement, the building owner must test the actuator per program procedures, and report the results to Invensys' Program Coordination Office on the required forms. Invensys will replace those actuators that fail to properly function during testing.

Building owners with dampers manufactured by Ruskin Manufacturing Co. may have already participated in a similar Replacement Actuator Program conducted by Ruskin. Those building owners also should review this announcement and participate in this recall, as it provides follow-up on Ruskin's program.
