Compartment volume = 3500 cubic feet Flaming Resin Detector Alarm Time A 0:58 B 0:41 C 1:16 D 1:05 Alarm time is the average of 2 tests. Resin Block
Compartment volume = 3500 cubic feet Flaming Resin Detector Alarm Time A 1:13 B 1:08 C 1:22 D 1:13 Alarm time is the average of 2 tests. Resin Block
Compartment volume = 3500 cubic feet Smoldering Resin Detector Alarm Time A 1:01 B :52 C 1:45 D 1:43* Alarm time is the average of 2 tests. Resin Block * No alarm for one of the tests.
Future Activities Complete resin block testing in DC-10 below floor compartment. Run a variety of fires in DC-10 (alcohol soaked rags, suitcases, shredded newspaper). Develop possible alarm algorithms and compare detection times for the above fires and resin blocks for both the 707 tests and the DC-10 tests.
