October 2, 2002Invensys Building Has Recalled
Siebe Actuators in Building Fire/Smoke Dampers
Park, IL (SafetyAlerts)
- Invensys Building Systems has recalled
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.
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.
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 www.regcen.com/MA200.
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.
