Also, if you have some documentation on WHEEL WELL FIRE detection.
How many detectors by wheel bay ?
What's the conditions to trigger a warning ?
Can a high brake temp trigger a fire warning as well ?

Thanks
According to the 757 maintenance training manual, the figures go from 0 to 9 (not 10 as I mentioned earlier). This resembles a range from 0 to 690°C. There are three colors available on the lower EICAS display. When a brake reaches value "5" (or approx. 500°C) there is a color change, together with a "brake" light, next to the three greens and the "door" light. Every single brake has a temp probe and these 8 signals go to a brake monitoring computer. A photo with the blocks on the EICAS and the brake light: http://www.airliners.net/open.file/0529570/M/
If I have time I will look up the fire warning issue.
