Explain cargo smoke detection (what powers it, how many detectors, how many have to agree for warning, what turns off when smoke detected, etc)
ESS powered
Each compartment has independent smoke detection systems
3 FWD smoke detectors
At least 2 have to be in agreement to generate FWD cargo smoke warnings
After smoke detected, circulation fan automatically turns off and vent outflow valve closes
2 AFT smoke detectors
Both must be in agreement
