Source: CPSC Recall #03003
Recall Date
2002-10-02
Manufacturer
Invensys Building Systems, of Love Park, Ill.
Units Affected
Up to 560,000
Products Involved
Siebe actuators
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.
Reported Injuries
Building owners, damper manufacturers, and fire and safety investigators have reported dampers not closing during testing.
