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

Hazard/Reason: 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.
