lustrates the relationship between the ignition source
configurations and the actuation times of the smoke detectors and
sprinklers. From Test 3, Test 5, Test 6 and Test 7, it is clear that when
the ignition source is near a corner, the plume corner effect greatly
increases, thus activating smoke detectors and sprinklers first in
that corner, and swiftly actuating fire suppression thereafter. Fig. 10
shows the flow temperatures at sprinklers S1-S4, via thermocouple
trees TC8, TC15, TC14 and TC 7, respectively. Flow temperature TC8
at the first actuated sprinkler (S1) in Test 5 rises faster, as shown in
