Engine/Generator Bay Operating Temperatures

[gulfquest2]

After reading the fire stories recently posted here, I have become
much more aware of my fire extinguisher status onboard. After
servicing my factory ABC units, I thought about installing automatic
units in both the engine bay and the generator bay.

Does anyone have an idea of the temperature ranges in these bays under
worst case scenarios (short of fire, that is...)? The automatic units
I have are preset to go off at 212 degrees Fahrenheit and I am
concerned that the presets are too low especially when driving in the
Southwest in summertime. Doees anybody have any ideas?
