CPSC, Invensys Building Systems Announce Recall of Siebe Actuators in Building Fire/Smoke Dampers (03502)

U.S. CPSCFireOct 2, 2002

Hazard

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.

Remedy

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.

Incidents & injuries

Building owners, damper manufacturers, and fire and safety investigators have reported dampers not closing during testing.
