Description'of the Problem An operability test' of a representative sample of Quality Assurance Category
'II and Category III, ' UL-listed scurtain-type fire dar-s revealed that some
~
dampers. fail ed ~ to satisfactorily close under a'r flow and pressure conditions. The test was performed by American Warming and Ventilating, Inc.,
- at our request.
J,'g Due to the failuie.of;some Quality Assurance Category IL and III curtain-type fire-dampers to'.seti5factorily close during testing in the presence of air
-flow, an evaluation of Quality Assurance Category I curta n-type f re dampers i
i
^
is being made, to ensure that they will close against the system air flow.
This evaluation,. is based on the test results of Quality Assurance Category II L
-and --III' dampers.
Category I curtain-type fire dampers have been supplied.to P
Nine Mile Point 2 by Pacific Air Products.
The; matter is still under investigation-and a final report will be submitted by August 29, 1985
